Abstract

In Wireless Sensor Network during routing of packets, energy loss may occur which leads to dropping of packets. This loss of packets is caused due to collision and interference in the channel. To overcome this issue a routing protocol is developed to improve the routing performance of the hob by hop wireless mesh network greedy forwarding in sensor network in terms of latency through minimum hop count, energy and quality link. The protocol used is DORP protocol. Through cognitive sensing an efficient routing is carried out. We evaluate DORP for collision in the physical layer with symbol level simulation, and evaluate its network level representation, by comparing it with broadcast CSMA/CA protocol. The advantage is that the delay obtained through the schemes of cognitive network by sensing and routing is comparative to the network range.
