An efficient node infirmity tracking scheme with stable supportive route for reliable data transmission in WSN

The advance of technology in wireless sensor networks is increased nowadays. In this network, minimizing the battery consumption is most enormous challenge. For reliable data transmission, effective routing is required. In this work, an efficient node infirmity tracking scheme with stable supportive route for reliable data transmission is proposed. Problem Statement: Sensor nodes sense the data and forwards to CH. If there is any failure of edge node occurs then it needs to send the packet again. Retransmission of data causes overload in network. The proposed work concentrates on these issues. It consists of four phases: The first phase includes link establishment. In second phase, edge node failure is detected. In third phase, the disability of nodes is identified by using Infirmity Tracking Scheme (ITS). Finally in last phase, Stable Supportive Path Routing Algorithm (SSPRA) is used to find the supportive path in network if any failure of path occurs. It maintains the progression of data transmission and link stability. Outcome: It results minimized consumption of energy and balance load in network. Simulation is carried out and found it achieves better performance than existing algorithms in comparing metrics connectivity ratio, end to end delay, overhead, throughput and packet delivery ratio.
