COOPERATIVE PROTOCOL FOR QOS ROUTING IN WIRELESS SENSOR NETWORKS

Abstract

In cooperative networks, optimum path should be selected based on QoS parameters and then the node will recruit the
neighboring nodes to form a cluster and assist in communication. QoS based routing for wireless sensor networks helps to select
optimum path for routing and it improves the overall performance of the network. In this paper, we have modeled a QoS based
cooperative protocol for wireless sensor networks. We have analyzed the energy consumption of nodes and throughput. We
have compared the energy consumption and throughput of our proposed QoS based cooperative protocol with existing
cooperative transmission protocol. Network Simulator 2 (NS 2) is used to model the method and the comparison results show
that the QoS based cooperative protocol outperforms the existing cooperative protocol in terms of energy of nodes and
throughput.
