Abstract

Healthcare application of wireless sensor network has seen tremendous boost in recent times because of wearable devices. In such scenarios, the routing has to be done effectively and securely.In such networks the packet delivery and E2E delay are of prime importance. The proposed scheme modifies the selection of the optimized path using AODV routing protocol by considering the fitness value of the nodes in the possible paths. The optimized path is the one that has nodes with highest remaining energy and highest packet delivery ratio. The proposed and the existing schemes were implemented in network simulator 2.35 and the performance parameters were throughput, packet delivery ratio and end to end delay. These parameters showed an improved over the existing scheme.
