--- _id: '8534' abstract: - lang: eng text: "We propose two protocols for distributed priority queues (denoted by 'heap' for simplicity in this paper) called SKEAP and SEAP. SKEAP realizes a distributed heap for a constant amount of priorities and SEAP one for an arbitrary amount. Both protocols build on an overlay, which induces an aggregation tree on which heap operations are aggregated in batches, ensuring that our protocols scale even for a high rate of incoming requests. As part of SEAP we provide a novel distributed protocol for the k-selection problem that runs in time O(log n) w.h.p. SKEAP guarantees sequential consistency for its heap operations, while SEAP guarantees serializability. SKEAP and SEAP provide logarithmic runtimes w.h.p. on all their operations. \r\nSKEAP and SEAP provide logarithmic runtimes w.h.p. on all their operations with SEAP having to use only O(log n) bit messages." author: - first_name: Michael full_name: Feldmann, Michael id: '23538' last_name: Feldmann - first_name: Christian full_name: Scheideler, Christian id: '20792' last_name: Scheideler citation: ama: 'Feldmann M, Scheideler C.

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the adversary has an almost up-to-date information of\r\nthe network topology as it can observe an only slightly outdated topology that\r\nis at least $2$ rounds old.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.

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.
