Parametric Protocol for Energy Efficient Cluster Head Selection (PPEECS) in WSNs

Energy Efficient Routing is a crucial issue in Wireless sensor networks (WSNs). This paper proposes a novel algorithm, Parametric Protocol for Energy Efficient Cluster Head Selection (PPEECS) in WSN, which consists of two phases; Region formation phase and Cluster Head (CH) selection phase. In prior phase we divide the network into several regions depending upon node density distribution. The later phase allocates a CH per region. The CH selection depends upon relevant parameters related to energy dissipation of nodes. This routing protocol increases the overall lifetime of the network by uniform and effective energy utilization. Simulations show that PPEECS increases network lifetime by all metrics i.e. FND (First Node Dies) by 22%, HNA (Half of the Nodes Alive) by 60% and LND (Last Node Dies) by 50% when compared with an existing protocol, LEACH. Also, PPEECS has a better network lifetime when compared with multihop-LEACH; FND -74%, HNA - 53% and LND - 43 %.
