Topology and Power Management Routing for Reliability in Ad-hoc Networks

Ad-hoc networks have a scarcity of resources, and exist in a dynamic topology. The lack of an established infrastructure places additional responsibilities on each node within these networks. Because of these constraints associated with ad-hoc networks each node must use a global perspective when making routing path decisions. Resources such as battery power in an ad-hoc network are finite which makes power conservation a major concern. Power conservation techniques in ad-hoc networks have been successful however transmission energy continues to influence research in the area. In this paper, energy and topology information were applied to routing for the purpose of advancing network communication for improvement in reliability of a network under power constraints. The results showed that a relationship exists between ad-hoc topology, a node's residual energy, and the extension of network lifetime. This work extended the lifetime of various topologies while maintaining the same or better data transmission qualities.
