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.
