FDRRP - A Reliable Routing Protocol for Wireless Sensor Networks

An important challenge in Wireless Sensor Networks used in industrial applications is its reliability with respect to guaranteed delivery while maintaining minimum overhead. Although the traditional ad hoc routing protocols are designed for obtaining the maximum throughput, they cannot guarantee reliability. For process control applications, every information conveyed by every sensor is important. This paper proposes a reliable hybrid routing protocol called Fisheye State Routing (FSR) and Dynamic Source Routing (DSR) combined Reliable Routing Protocol (FDRRP) which combines the advantages of DSR and FSR to achieve better reliability in WSN. The performance of FDRRP is verified through simulation experiments and analysis. It is observed that the trade-off between end-to-end delay and routing overhead is well balanced in FDRRP when compared to DSR and FSR protocols without compromising much on the computational complexity.
