Shortest Path Energy Efficient Hierarchal Clustering Protocol for Wireless Sensor Networks
WSN lifetime depends on the energy consumptions of its sensor nodes. Hence, the major design issue which requires to be addressed, to prolong the lifespan of WSN, is energy efficiency. In contemporary hierarchical cluster-based routing protocols, communication within the network is less energy efficient which leads to the accelerated aging of these energy deficient networks. This work presents a hierarchical cluster based routing protocol named Shortest Path Energy Efficient Hierarchal Clustering (SPEEHC) protocol that considers the unique characteristics of WSN. SPEECH aims at preserving the limited energy of sensor networks via optimal cluster formation and shortest path communications within the network. It is observed from a simulation that SPEECH is better in utilizing the limited energy of the network efficiently.
