Energy And Location Aware Cluster Routing Protocol For Wireless Sensor Networks (ELACRP)

摘要

This paper proposes an ensemble protocol called Energy and Location Aware Cluster Routing Protocol (ELACRP) for wireless sensor networks. The location information model and energy consumption model are adapted. The neighbor node election operation is initiated once when the network is deployed. The cluster head selection mechanism is performed based on the residual energy of sensor nodes. The cluster head mechanism chooses the sensor node having maximum residual energy. Clustering is performed based on the nodes location information conceived from the GPS location information. The metrics number of packets delivered to the sink, energy utilization rate, the energy standard deviation and average hops are taken to compare the performance of the ELACRP with AELAR protocol [13]. Simulations are performed using NS2 and the outcome results depicts that the proposed ELACRP performs better than that of AELAR protocol [13] in terms of the chosen performance metrics.
