Topology Control for Energy Saving in Wireless Ad Hoc Networks

Abstract

In a wireless ad hoc network, end to end connectivity among nodes is established using in- termediate forwarding nodes. A node chose one of its neoghbors for forwarding its packets to a particular destination. Having more nodes in neighborhood (dense network) increases probability of end to end connectivity but consumes more energy (due to unnecessary re- ception of packets by all nodes in communication range and higher transmit power); on the other hand having a few nodes in neighborhood may reduce energy consumption but reduce the probability of end to end connectivity. We study K-neighbourhood topology con- trol protocol and analyze e ect of value of K on energy consumption and packet delivery ratio for di fferent network scenarios using simulations.
