In greedy routing, each relay node forwards the message to a neighbor (also called successor) that is closer to the destination. However, the successor candidate set (SCS) is different every time when the relative location of relay node to the destination changes. The configuration in the entire network when all the succeeding paths from a relay node are blocked by local minima is irregular and its...
Ad hoc networks are promising but are vulnerable to selfish and malicious attacks. One kind of malicious attack, hidden wormhole attacks, can be mounted easily and be immune to cryptographic techniques. Wormholes distort network topology, and degrade the performance of applications such as localization and data collection. A wormhole attack is one of the most severe threats to an ad hoc network. Unfortunately,...
Due to resource scarcity, a paramount concern in ad hoc networks is utilizing limited resources efficiently. The self-organized nature of ad hoc networks makes the network utility-based approach an efficient way to allocate limited resources. However, the effect of link instability has not yet been adequately addressed in literature. To efficiently address the routing problem in ad hoc networks, we...
