Transmission Range Adjustment for Enhancing Network Lifetime in WSNs

Wireless Sensor Nodes (WSNs) are densely deployed in a hostile environment to monitor, detect, and analyze the physical phenomenon and consume considerable amount of energy while transmitting the information. So, some limitation will occur on the network lifetime of the battery power and energy conservation is a challenging issue. This paper proposes a new novel namely Transmission Distance and Transmission Range based Unequal Clustering Protocol (TDTRUCP) which follows the following parameters, 1) Location of each node, 2) Distance of each node from base station, 3) Transmission distance is unequal and Transmission Range is unequal and 4) Cluster sizes are unequal. In this research, the clustering protocol is implemented with unequal sizes based on the transmission distance and cluster member nodes. It reduces the energy consumption of cluster reconstruction. The simulation results show that the proposed method outperforms existing system in terms of network parameters such as delay, energy consumption, throughput, PDR, accuracy, computation overhead and scalability using Network Simulator-2. Finally, the performance analysis indicates that the proposed method is effective in reducing the energy consumption than the existing techniques.
