Abstract
Clustering based routing protocols have a pivotal role in wireless sensor networks (WSN) due to efficient energy consumption of limited power sensor node that is the prime challenge in WSN. Intra-cluster transmission and cluster size have great impact on balancing energy consumption within cluster and network. However, they play minor role in traditional routing protocols. In this paper, authors will offer mathematical analysis to provide judging metric that define energy efficient intra-cluster transmission. This metric is called threshold distance which is exploited in determining optimum cluster size. Based on the optimum cluster size, centralized energy aware grid clustering protocol (CEAG) will be proposed. Mat lab simulator will be utilized for appreciating the proposed protocol. The simulation results manifested that CEAG attains maximum network life tie and throughput in comparison with the existing protocols such as LEACH, K-LEACH, Energy-LEACH, DCHS and MOD-LEACH.
