A Distributed Topology Control Scheme for Wireless Sensor Networks using Geographic Aided Chain Based Routing

摘要

Wireless sensor nodes have energy constraints, so it is important that the nodes in wireless sensor network and MANET utilize very minimal energy as possible. In this work an efficient input topology and routing protocol to achieve energy efficiency and also to increase lifetime of the sensor nodes is proposed. The improved Geography informed Smart Boundary Yao Gabriel graph algorithm with Chain based routing algorithm is proposed. This algorithm has good energy efficiency characteristics, low interference and provides good connectivity than existing algorithm. The local decision is made by all the nodes in network and maintains the connectivity with efficient global topology. Simulation results are presented with energy efficiency and packet delivery ratio comparisons.
