Abstract—Node mobility is generally regarded as a hazard for geographic routing, causing a degradation of performance or even persistent routing failures. In this paper we pursue an opposite view where it is possible to take advantage of mobility to enhance greedy forwarding in geographic routing. A concept named motion potential, combining node mobility patterns with node position information, is introduced to help make forwarding decisions. Simulation results show that our approach behaves well and competes favorably with conventional geographic routing, especially under the scenario of low network density and high node mobility.

Improving Quality of Service Routing in Mobile Ad Hoc Networks Using OLSR
Mobile ad hoc networks (MANET) are constructed by mobile nodes without access point. Since MANET has certain constraints, including power shortages, an unstable wireless environment and node mobility, more power-efficient and reliable routing protocols are needed. The OLSR protocol is an optimization of the classical link state algorithm. OLSR introduces an interesting concept, the multipoint r...

Mobile Ad hoc networks (MANETs) are composed of mobile stations communicating through wireless links, without any fixed backbone support. In these networks, limited power energy supply, and frequent topology changes caused by node mobility, makes their routing a challenging problem. TORA is one of the routing protocols that successfully copes with the nodes’ mobility side effects, but it do...

متن کاملA self-healing On-demand Geographic Path Routing Protocol for mobile ad-hoc networks
We present a self-healing On-demand Geographic Path Routing Protocol (OGPR) for mobile ad-hoc networks. OGPR is an efficient, stateless, and scalable routing protocol that inherits the best of the three well-known techniques for routing in ad-hoc networks, viz., greedy forwarding, reactive route discovery, and source routing. In OGPR protocol, source nodes utilize the geographic-topology inform...
متن کاملContention-based forwarding for mobile ad hoc networks
Existing position-based unicast routing algorithms which forward packets in the geographic direction of the destination require that the forwarding node knows the positions of all neighbors in its transmission range. This information on direct neighbors is gained by observing beacon messages each node sends out periodically. Due to mobility, the information that a node receives about its neighb...
