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"}],"citation":{"ieee":"D.

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."}],"user_id":"11108","ddc":["040"],"citation":{"bibtex":"@inproceedings{Scheideler_Setzer_2018, title={Relays: A New Approach for the Finite Departure Problem in Overlay Networks}, DOI={10.1007/978-3-030-03232-6_16}, booktitle={Proceedings of the 20th International Symposium on Stabilization, Safety, and Security of Distributed Systems (SSS 2018)}, author={Scheideler, Christian and Setzer, Alexander}, year={2018} }","mla":"Scheideler, Christian, and Alexander Setzer. “Relays: A New Approach for the Finite Departure Problem in Overlay Networks.” Proceedings of the 20th International Symposium on Stabilization, Safety, and Security of Distributed Systems (SSS 2018), 2018, doi:10.1007/978-3-030-03232-6_16.","chicago":"Scheideler, Christian, and Alexander Setzer. “Relays: A New Approach for the Finite Departure Problem in Overlay Networks.” In Proceedings of the 20th International Symposium on Stabilization, Safety, and Security of Distributed Systems (SSS 2018), 2018. https://doi.org/10.1007/978-3-030-03232-6_16.","ama":"Scheideler C, Setzer A.

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.

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.","lang":"eng"}],"ddc":["040"],"user_id":"20792"},{"doi":"10.1007/978-3-319-69084-1_17","date_updated":"2022-01-06T06:51:19Z","language":[{"iso":"eng"}],"series_title":"Lecture Notes in Computer Science","title":"A Self-Stabilizing General De Bruijn Graph","external_id":{"arxiv":["1708.06542"]},"publication_status":"published","publication_identifier":{"isbn":["978-3-319-69083-4"]},"project":[{"_id":"1","name":"SFB 901"},{"name":"SFB 901 - Subprojekt A1","_id":"5"},{"_id":"2","name":"SFB 901 - Project Area A"}],"department":[{"_id":"79"}],"intvolume":" 10616","_id":"125","citation":{"mla":"Feldmann, Michael, and Christian Scheideler. “A Self-Stabilizing General De Bruijn Graph.” Proceedings of the 19th International Symposium on Stabilization, Safety, and Security of Distributed Systems (SSS), vol. 10616, Springer, Cham, 2017, pp. 250–64, doi:10.1007/978-3-319-69084-1_17.","bibtex":"@inproceedings{Feldmann_Scheideler_2017, series={Lecture Notes in Computer Science}, title={A Self-Stabilizing General De Bruijn Graph}, volume={10616}, DOI={10.1007/978-3-319-69084-1_17}, booktitle={Proceedings of the 19th International Symposium on Stabilization, Safety, and Security of Distributed Systems (SSS)}, publisher={Springer, Cham}, author={Feldmann, Michael and Scheideler, Christian}, year={2017}, pages={250–264}, collection={Lecture Notes in Computer Science} }","chicago":"Feldmann, Michael, and Christian Scheideler. “A Self-Stabilizing General De Bruijn Graph.” In Proceedings of the 19th International Symposium on Stabilization, Safety, and Security of Distributed Systems (SSS), 10616:250–64.

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.","lang":"eng"}],"date_created":"2017-10-17T12:41:33Z","has_accepted_license":"1","status":"public","publication":"Proceedings of the 28th ACM Symposium on Parallelism in Algorithms and Architectures (SPAA)","file_date_updated":"2018-03-21T10:41:40Z","author":[{"last_name":"Drees","full_name":"Drees, Maximilian","first_name":"Maximilian"},{"last_name":"Gmyr","full_name":"Gmyr, Robert","first_name":"Robert"},{"first_name":"Christian","full_name":"Scheideler, Christian","last_name":"Scheideler","id":"20792"}],"file":[{"file_size":352996,"file_id":"1518","creator":"florida","date_updated":"2018-03-21T10:41:40Z","content_type":"application/pdf","success":1,"relation":"main_file","date_created":"2018-03-21T10:41:40Z","file_name":"215-SPAA16-Drees_Gmyr_Scheideler.pdf","access_level":"closed"}],"_id":"215","page":"417--427","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.","lang":"eng"}],"ddc":["040"],"user_id":"477","file_date_updated":"2018-03-21T12:59:29Z","publication":"Proceedings of the 30th International Symposium on Distributed Computing (DISC)","author":[{"first_name":"Christian","full_name":"Scheideler, Christian","last_name":"Scheideler","id":"20792"},{"first_name":"Alexander","full_name":"Setzer, Alexander","last_name":"Setzer","id":"11108"},{"id":"11319","last_name":"Strothmann","full_name":"Strothmann, Thim Frederik","first_name":"Thim Frederik"}],"file":[{"access_level":"closed","date_created":"2018-03-21T12:59:29Z","file_name":"142-SchSetStrDISC16.pdf","date_updated":"2018-03-21T12:59:29Z","content_type":"application/pdf","relation":"main_file","success":1,"file_size":209638,"file_id":"1558","creator":"florida"}],"date_created":"2017-10-17T12:41:19Z","status":"public","has_accepted_license":"1"},{"doi":"10.1145/2809806","date_updated":"2022-01-06T06:58:03Z","project":[{"_id":"1","name":"SFB 901"},{"name":"SFB 901 - Subprojekt C1","_id":"13"},{"_id":"4","name":"SFB 901 - Project Area C"}],"department":[{"_id":"79"}],"title":"IRIS: A Robust Information System Against Insider DoS Attacks","page":"18:1--18:33","type":"journal_article","citation":{"chicago":"Eikel, Martina, and Christian Scheideler. “IRIS: A Robust Information System Against Insider DoS Attacks.” Transactions on Parallel Computing, no. 3 (2015): 18:1--18:33. https://doi.org/10.1145/2809806.","ama":"Eikel M, Scheideler C.

We allow a current insider to have complete knowledge about the information system and to have the power to block any ϵ-fraction of its servers by a DoS attack, where ϵ can be chosen up to a constant. The task of the system is to serve any collection of lookup requests with at most one per nonblocked server in an efficient way despite this attack. Previously, scalable solutions were only known for DoS attacks of past insiders, where a past insider only has complete knowledge about some past time point t0 of the information system. Scheideler et al. [Awerbuch and Scheideler 2007; Baumgart et al. 2009] showed that in this case, it is possible to design an information system so that any information that was inserted or last updated after t0 is safe against a DoS attack. But their constructions would not work at all for a current insider. The key idea behind our IRIS system is to make extensive use of coding. More precisely, we present two alternative distributed coding strategies with an at most logarithmic storage overhead that can handle up to a constant fraction of blocked servers."}]}]
