AN EFFICIENT UNEQUAL CLUSTERING AND DATA DELIVERY ROUTING PROTOCOL FOR IMPROVING LIFETIME OF WIRELESS SENSOR NETWORKS

Energy consumption of sensor nodes in wireless sensor networks (WSNs) is an extremely basic issue. Sensor nodes are typically control compelled, have constrained calculation and memory assets. Clustering is one mechanism to design energy efficient sensor network routing protocols. The clustering approach groups the network into sets of sensor nodes and a cluster head (CH) is decided for each centering cluster. The members from the cluster can't send data straightforwardly to base station (BS), these members send data to the CH and CH advances it to BS. In this strategy, CHs closer to the base station are loaded with substantial transfer movement and have a tendency to wind up latent before time. This leaves the system territories revealed and causes the hotspot problem. With a specific aim to keep the system from hotspot problem, unequal clustering and routing protocol is proposed for load adjusting between the CHs based on mutation chemical reaction optimization algorithm which is named as MCROUCRP. This protocol results in productive cluster head determination, unequal cluster arrangement and energy efficient data delivery to BS over multihop routing. The MCRO-UCRP is simulated in NS2.35 simulator over different WSN scenarios by changing number of sensors and CHs. The results of proposed protocol is better, contrasted with existing protocols as far as different network performance measurements.
