Cognitive forwarding for real-time routing in WSN

Abstract

In Wireless Sensor Network (WSN), sensors gather information about the physical world and the base station makes decision and then performs appropriate actions upon the environment. This technology enables a user to effectively sense and monitor from a distance in real-time. WSN demands real- time forwarding which means messages in the network are delivered according to their end-to-end deadlines (packet lifetime). This paper proposes cognitive forwarding for real-time routing protocol with load distribution (RTLD) that provides efficient power consumption, high packet delivery ratio and minimum control packet overhead in WSN. It combines packet reception rate (PRR), packet velocity and the remaining power to achieve real-time routing in WSN. The proposed mechanism has been successfully studied through simulation work.
