Abstract
Conference Title: ICC 2014 - 2014 IEEE International Conference on Communications Conference Start Date: 2014, June 10 Conference End Date: 2014, June 14 Conference Location: Sydney, Australia In this paper, we propose an Application-aware Threshold-based Centralized Energy Efficient Clustering (ATCEEC) protocol for routing in Wireless Sensor Networks (WSNs). The proposed protocol assumes that each wireless sensor (node) is capable of sensing two types of environmental dynamics; temperature and humidity. Operation of ATCEEC is based on an advanced central control algorithm, where, Base Station (BS) is responsible for the selection of Cluster Heads (CHs). This selection is carried out on the bases of nodes' residual energy, average energy of the network, and relative distance between nodes and BS. ATCEEC achieves significant stability, extended network lifetime and better control over the network operation. Our hybrid protocol is suitable for both proactive and reactive networks. Simulation results show that ATCEEC yields maximum network lifetime and stability period as compared to the selected protocols. [PUBLICATION ABSTRACT]
