Abstract

QoS of WSN routing protocols are measured in terms of energy-efficiency, end-to-end delay and packet delivery ratio. Multi-path routing provides an easy mechanism to distribute traffic, balance networks load and fault tolerance. However disadvantage of employing multipath routing is delay in path switching and every node has to maintain information of every other node and has to update the whole information periodically which consumes lot of energy. So to overcome this drawback we employ clustering mechanism which divides the entire network in to clusters and multipaths are restricted to these clusters by which traffic will be distributed only to the cluster without propagating entire network and does not cause delay, energy wastage and increases delivery ratio between nodes. Performance is compared between proposed protocol and EQSR protocol by simulating in NS2.
