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...
Efficient geometric routing algorithms have been studied extensively in two-dimensional ad hoc networks, or simply 2D networks. These algorithms are efficient and they have been proven to be the worst-case optimal, localized routing algorithms. However, few prior works have focused on efficient geometric routing in 3D networks due to the lack of an efficient method to limit the search once the greedy...
In wireless ad-hoc sensor networks, an important issue often faced in geographic greedy forwarding routing is the "local minimum phenomenon" which is caused by deployment holes and blocks the forwarding process. In this paper, we provide a new information model for the geographic greedy forwarding routing that only forwards the packet within the so-called request zone. Under this new information...
