Transmission Power Controlled Topology Control in Wireless Sensor Network

The topology control is a vital process to maximize the lifetime of wireless sensor networks. Since sensor nodes are energy constraint, so our aim also is to maximize the network lifetime by utilizing the energy of nodes very efficiently. In this paper, we propose (TPCTC) a topology control algorithm with transmission power adjustment based on optimal no. of neighbours to raise the network energy- efficiency and the network throughput and to cope with the trade-off between the energy balance and energy efficiency, a non-linear optimization problem is formulated to find the optimal route nodes and their various transmission ranges. Our simulation results(using Matlab) show that in comparison to LEACH and Direct communication, TPCTC(transmission power controlled topology control) achieve significant increment in network lifetime.
