Wireless Sensor Networks (WSNs) have become one of the most prominent areas of research in the field of modern communication systems. But unlike IP based routing, WSNs focus on data centric communication. Thus routing is one of the important issues to be considered for a wireless network. As sensor networks are generally deployed in hostile environments, batteries cannot be recharged often. Thus energy conservation is one of the important design parameters for WSNs. Many energy aware routing protocols were proposed in the literature. Cluster based algorithms were proved to be better compared to multi hop routing. In this paper an attempt has been made in proposing a novel cluster based energy efficient routing algorithm for WSNs, Energy Aware Threshold based Efficient Clustering (EATEC) algorithm, which incorporates a centralized process of Base Station (BS) selecting Cluster Heads (CH) based on its residual energy. The proposed algorithm proves to be better compared to LEACH.
