Second, we develop a network based on the hypercube that maintains connectivity under adversarial DoS-attacks. For the DoS-attacks we use the notion of a Omega(log log n)-late adversary which only has access to topological information that is at least Omega(log log n) rounds old. Finally, we develop a network that combines both churn- and DoS-resistance. The networks gain their robustness through constant network reconfiguration, i.e., the topology of the networks changes constantly. Our reconguration algorithms are based on node sampling primitives for expanders and hypercubes that allow each node to sample a logarithmic number of nodes uniformly at random in O(log log n) communication rounds. These primitives are specific to overlay networks and their optimal runtime represents an exponential improvement over known techniques. Our results have a wide range of applications, for example in the area of scalable and robust peer-to-peer systems.' author: - first_name: Maximilian full_name: Drees, Maximilian last_name: Drees - first_name: Robert full_name: Gmyr, Robert last_name: Gmyr - first_name: Christian full_name: Scheideler, Christian id: '20792' last_name: Scheideler citation: ama: 'Drees M, Gmyr R, Scheideler C.

In recent years, various self-stabilizing overlay networks have been proposed that have the advantage of being able to recover from any illegal state. However, the vast majority of these networks cannot give any guarantees on its functionality while the recovery process is going on. We are especially interested in searchability, i.e., the functionality that search messages for a specific identifier are answered successfully if a node with that identifier exists in the network. We investigate overlay networks that are not only self-stabilizing but that also ensure that monotonic searchability is maintained while the recovery process is going on, as long as there are no corrupted messages in the system. More precisely, once a search message from node u to another node v is successfully delivered, all future search messages from u to v succeed as well. Monotonic searchability was recently introduced in OPODIS 2015, in which the authors provide a solution for a simple line topology.We present the first universal approach to maintain monotonic searchability that is applicable to a wide range of topologies. As the base for our approach, we introduce a set of primitives for manipulating overlay networks that allows us to maintain searchability and show how existing protocols can be transformed to use theses primitives.We complement this result with a generic search protocol that together with the use of our primitives guarantees monotonic searchability.As an additional feature, searching existing nodes with the generic search protocol is as fast as searching a node with any other fixed routing protocol once the topology has stabilized. author: - first_name: Christian full_name: Scheideler, Christian id: '20792' last_name: Scheideler - first_name: Alexander full_name: Setzer, Alexander id: '11108' last_name: Setzer - first_name: Thim Frederik full_name: Strothmann, Thim Frederik id: '11319' last_name: Strothmann citation: ama: 'Scheideler C, Setzer A, Strothmann TF.

So far, this problem is understood only in simplistic single-hop or unit disk graph models. We in this paper initiate the study of MAC protocols for the SINR interference model (a.k.a. physical model). This paper makes two contributions. First, we introduce a new adversarial SINR model which captures a wide range of interference phenomena. Concretely, we consider a powerful, adaptive adversary which can jam nodes at arbitrary times and which is only limited by some energy budget. Our second contribution is a distributed MAC protocol called Sade which provably achieves a constant competitive throughput in this environment: we show that, with high probability, the protocol ensures that a constant fraction of the non-blocked time periods is used for successful transmissions.' author: - first_name: Adrian full_name: Ogierman, Adrian last_name: Ogierman - first_name: Andrea full_name: Richa, Andrea last_name: Richa - first_name: Christian full_name: Scheideler, Christian id: '20792' last_name: Scheideler - first_name: Stefan full_name: Schmid, Stefan last_name: Schmid - first_name: Jin full_name: Zhang, Jin last_name: Zhang citation: ama: 'Ogierman A, Richa A, Scheideler C, Schmid S, Zhang J.

While the external network lies outside of the control of the nodes (or in our case, the monitoring protocol running in them) and might be exposed to continuous changes, the internal network is fully under the control of the nodes. As an example, consider a group of users with mobile devices having access to the cell phone infrastructure. While the network formed by the WiFi connections of the devices is an external network (as its structure is not necessarily under the control of the monitoring protocol), the connections between the devices via the cell phone infrastructure represent an internal network (as it can be controlled by the monitoring protocol). Our goal is to continuously monitor properties of the external network with the help of the internal network. We present scalable distributed algorithms that efficiently monitor the number of edges, the average node degree, the clustering coefficient, the bipartiteness, and the weight of a minimum spanning tree. Their performance bounds demonstrate that monitoring the external network state with the help of an internal network can be done much more efficiently than just using the external network, as is usually done in the literature. author: - first_name: Robert full_name: Gmyr, Robert last_name: Gmyr - first_name: Kristian full_name: Hinnenthal, Kristian id: '32229' last_name: Hinnenthal - first_name: Christian full_name: Scheideler, Christian id: '20792' last_name: Scheideler - first_name: Christian full_name: Sohler, Christian last_name: Sohler citation: ama: 'Gmyr R, Hinnenthal K, Scheideler C, Sohler C.

Motivated by a result of Ben-Or and Bar-Joseph (1998), showing that any consensus algorithm that is resilient against a linear number of crash faults requires $\\tilde \\Omega(\\sqrt n)$ rounds in an n-node network against an adaptive adversary, we consider a late adaptive adversary, who has full knowledge of the network state at the beginning of the previous round and unlimited computational power, but is oblivious to the current state of the nodes. \r\n\r\nOur main contributions are randomized distributed algorithms that achieve consensus with high probability among all except a small constant fraction of the nodes (i.e., \"almost-everywhere'') against a late adaptive adversary who can block up to ε n$ nodes in each round, for a small constant ε >0$. Our first protocol achieves binary almost-everywhere consensus and also guarantees a decision on the majority input value, thus ensuring plurality consensus. We also present an algorithm that achieves the same time complexity for multi-value consensus. Both of our algorithms succeed in $O(log n)$ rounds with high probability, thus showing an exponential gap to the $\\tilde\\Omega(\\sqrt n)$ lower bound of Ben-Or and Bar-Joseph for strongly adaptive crash-failure adversaries, which can be strengthened to $\\Omega(n)$ when allowing the adversary to block nodes instead of permanently crashing them. Our algorithms are scalable to large systems as each node contacts only an (amortized) constant number of peers in each communication round. We show that our algorithms are optimal up to constant (resp.\\ sub-logarithmic) factors by proving that every almost-everywhere consensus protocol takes $\\Omega(log_d n)$ rounds in the worst case, where d is an upper bound on the number of communication requests initiated per node in each round. We complement our theoretical results with an experimental evaluation of the binary almost-everywhere consensus protocol revealing a short convergence time even against an adversary blocking a large fraction of nodes." author: - first_name: Peter full_name: Robinson, Peter last_name: Robinson - first_name: Christian full_name: Scheideler, Christian id: '20792' last_name: Scheideler - first_name: Alexander full_name: Setzer, Alexander id: '11108' last_name: Setzer citation: ama: 'Robinson P, Scheideler C, Setzer A.

In fact, it is known that any online routing protocol has a poor performance in the worst case, in a sense that there is a distribution of nodes resulting in bad routing paths for that protocol, even if the nodes know their geographic positions and the geographic position of the destination of a message is known. The reason for that is that radio holes in the ad hoc network may require messages to take long detours in order to get to a destination, which are hard to find in an online fashion.\r\n\r\nIn this paper, we assume that the wireless ad hoc network can make limited use of long-range links provided by a global communication infrastructure like a cellular infrastructure or a satellite in order to compute an abstraction of the wireless ad hoc network that allows the messages to be sent along near-shortest paths in the ad hoc network. We present distributed algorithms that compute an abstraction of the ad hoc network in $\\mathcal{O}\\left(\\log ^2 n\\right)$ time using long-range links, which results in $c$-competitive routing paths between any two nodes of the ad hoc network for some constant $c$ if the convex hulls of the radio holes do not intersect. We also show that the storage needed for the abstraction just depends on the number and size of the radio holes in the wireless ad hoc network and is independent on the total number of nodes, and this information just has to be known to a few nodes for the routing to work.\r\n" author: - first_name: Daniel full_name: Jung, Daniel id: '37827' last_name: Jung - first_name: Christina full_name: Kolb, Christina id: '43647' last_name: Kolb - first_name: Christian full_name: Scheideler, Christian id: '20792' last_name: Scheideler - first_name: Jannik full_name: Sundermeier, Jannik id: '38705' last_name: Sundermeier citation: ama: 'Jung D, Kolb C, Scheideler C, Sundermeier J.

To rigorously study self-stabilizing solutions to this problem, the Finite Departure Problem (FDP) has been proposed [9]. In the FDP we are given a network of processes in an arbitrary state, and the goal is to eventually arrive at (and stay in) a state in which all leaving processes irrevocably decided to leave the system while for all weakly-connected components in the initial overlay network, all staying processes in that component will still form a weakly connected component. In the standard interconnection model, the FDP is known to be unsolvable by local control protocols, so oracles have been investigated that allow the problem to be solved [9]. To avoid the use of oracles, we introduce a new interconnection model based on relays. Despite the relay model appearing to be rather restrictive, we show that it is universal, i.e., it is possible to transform any weakly-connected topology into any other weakly-connected topology, which is important for being a useful interconnection model for overlay networks. Apart from this, our model allows processes to grant and revoke access rights, which is why we believe it to be of interest beyond the scope of this paper. We show how to implement the relay layer in a self-stabilizing way and identify properties protocols need to satisfy so that the relay layer can recover while serving protocol requests. author: - first_name: Christian full_name: Scheideler, Christian id: '20792' last_name: Scheideler - first_name: Alexander full_name: Setzer, Alexander id: '11108' last_name: Setzer citation: ama: 'Scheideler C, Setzer A.

We assume an adversary that may churn a\r\nconstant fraction $\\alpha n$ of nodes over the course of $\\mathcal{O}(\\log n)$\r\nrounds. In particular, the adversary has an almost up-to-date information of\r\nthe network topology as it can observe an only slightly outdated topology that\r\nis at least $2$ rounds old. Other than that, we only have the provably minimal\r\nrestriction that new nodes can only join the network via nodes that have taken\r\npart in the network for at least one round.\r\n Our contributions are as follows: First, we show that it is impossible to\r\nmaintain a connected topology if adversary has up-to-date information about the\r\nnodes' connections. Further, we show that our restriction concerning the join\r\nis also necessary. As our main result present an algorithm that constructs a\r\nnew overlay- completely independent of all previous overlays - every $2$\r\nrounds. Furthermore, each node sends and receives only $\\mathcal{O}(\\log^3 n)$\r\nmessages each round. As part of our solution we propose the Linearized DeBruijn\r\nSwarm (LDS), a highly churn resistant overlay, which will be maintained by the\r\nalgorithm. However, our approaches can be transferred to a variety of classical\r\nP2P Topologies where nodes are mapped into the $[0,1)$-interval." author: - first_name: Thorsten full_name: Götte, Thorsten id: '34727' last_name: Götte - first_name: Vipin Ravindran full_name: Vijayalakshmi, Vipin Ravindran last_name: Vijayalakshmi - first_name: Christian full_name: Scheideler, Christian id: '20792' last_name: Scheideler citation: ama: 'Götte T, Vijayalakshmi VR, Scheideler C.

These primitives are local in the sense that each node can apply them based on local knowledge and by affecting only its 1-neighborhood. Although the specific set of primitives we consider makes it possible to transform any (weakly) connected graph into any other (weakly) connected graph consisting of the same nodes, they cannot disconnect the graph or introduce new nodes into the graph, making them ideal in the context of supervised overlay network transformations. We prove that computing a minimum sequence of primitive applications (even centralized) for arbitrary G_s and G_t is NP-hard, which we conjecture to hold for any set of local graph transformation primitives satisfying the aforementioned properties. On the other hand, we show that this problem admits a polynomial time algorithm with a constant approximation ratio. author: - first_name: Christian full_name: Scheideler, Christian id: '20792' last_name: Scheideler - first_name: Alexander full_name: Setzer, Alexander id: '11108' last_name: Setzer citation: ama: 'Scheideler C, Setzer A.

For example, mobile phones may use ad-hoc connections via Bluetooth or Wi-Fi in addition to the cellular network to solve tasks more efficiently. Like in this case, the different communication modes may differ considerably in range, bandwidth, and flexibility. We build upon the model of Augustine et al. [SODA '20], which captures these differences by a \\emph{local} and a \\emph{global} mode. Specifically, the local edges model a fixed communication network in which $O(1)$ messages of size $O(\\log n)$ can be sent over every edge in each synchronous round. The global edges form a clique, but nodes are only allowed to send and receive a total of at most $O(\\log n)$ messages over global edges, which restricts the nodes to use these edges only very sparsely.\r\n\r\nWe demonstrate the power of hybrid networks by presenting algorithms to compute Single-Source Shortest Paths and the diameter very efficiently in \\emph{sparse graphs}. Specifically, we present exact $O(\\log n)$ time algorithms for cactus graphs (i.e., graphs in which each edge is contained in at most one cycle), and $3$-approximations for graphs that have at most $n + O(n^{1/3})$ edges and arboricity $O(\\log n)$. For these graph classes, our algorithms provide exponentially faster solutions than the best known algorithms for general graphs in this model.\r\nBeyond shortest paths, we also provide a variety of useful tools and techniques for hybrid networks, which may be of independent interest.\r\n" author: - first_name: Michael full_name: Feldmann, Michael id: '23538' last_name: Feldmann - first_name: Kristian full_name: Hinnenthal, Kristian id: '32229' last_name: Hinnenthal - first_name: Christian full_name: Scheideler, Christian id: '20792' last_name: Scheideler citation: ama: 'Feldmann M, Hinnenthal K, Scheideler C.
