The vision behind the Internet of Things (IoT) is that any things that need communications, are universally connected, and becoming an integral part of the future Internet. However, the existing of Low Power Networks (LPN) consisting of battery-powered nodes poses great challenge for traditional addressing and routing protocols. The paper proposes a geographical topology-enabled IPv6 addressing framework...
Geographic routing for wireless ad-hoc networks has a well known "local minimum" problem, which is caused by a "hole" that blocks the greedy forwarding process. Existing geographic routing algorithms use perimeter routing strategies to find a long detour path when such a situation occurs. In this paper, we propose a heuristic hole detecting algorithm which can identify the hole...
Geographic routing is an effective approach for finding a path to forward packets from a source to a destination in wireless ad hoc networks when nodes have location information. The basic strategy is to let each node select one of its neighbors that is closest to the destination as the next hop to forward the packet greedily. However, when there are void areas (holes), greedy routing does not work...
