Improved Topology Control Algorithm for MANETs

A mobile wireless ad hoc network is formed dynamically without a need for a pre-existing infrastructure. Frequent Topology changes leads to more processing and hence more power consumption. Reducing power consumption during node's life time is a challenging task. Adaptive Self-Configuring sEnsor Networks Topologies (ASCENT) is a topology control technique for reducing the power consumption during the node lifetime. In ASCENT, each node assesses its connectivity and adapts its participation in the multi-hop network topology based on the operating region. In this paper, I study some of the problems in ASCENT algorithm and propose a modified state diagram, which adaptively adjusts the states of individual nodes, to reduce redundancy. This helps to achieve the optimum number of Active nodes in the network. I implement the modified state diagram, and simulation results highlight that the improved ASCENT state diagram is able to achieve better performance than the original ASCENT algorithm.
