With advancement in communication technologies, the design of efficient and lightweight reliability protocols seems like an achievable goal. However, strategies for attacking and compromising communication reliability have also seen comparable advancement. As a result, reliability still remains a key concern for both the wired and wireless communication(More)
Preserving source location privacy in wireless sensor networks can be critical for several practical applications. Existing solutions proposed specifically for sensor networks rely on a combination of dynamic routing and dummy traffic to hide real event messages. While some privacy protection guarantees can be given, these solutions also tend to be(More)
In this paper, we make a case for using watchdogs to protect against misbehavior in dense wireless networks. We introduce “Generalized Watchdogs” and identify when and how watchdogs can be necessary and sufficient against misbehavior. We study feasibility of watchdog approach and show that the order of capacity bounds is preserved(More)
This paper considers reliable communication in presence of Byzantine faulty nodes, using multiple node-disjoint routes. To tolerate f Byzantine faults, at least 2f + 1 node-disjoint paths are needed between a source and destination node pair. However, often the faulty nodes' misbehavior manifests itself as a "disagreement" between information provided by(More)
Network designs with multichannel and multi-interface capabilities are fast emerging as the new solution to the high interference and low throughput problems faced by wireless mesh networks today. Multichannel capability, ideally, isolates transmissions over different channels and hence interference is expected to be minimized. Multi-interface capabilities(More)
