A Non Uniform Fault Tolerable Routing Protocol for Unequal Chain Length in Wireless Sensor Network

Electronics & Communication

Wireless sensor networks provide a significant con- tribution to the emerging field such as ubiquitous computing and ambient intelligence. Due to the inherent property of WSN, it is most vulnerable for reliability. In literature, most of the authors concern about network longevity and ignore fault tolerance. In this dissertation, we present A Non Uniform Fault Tolerable Routing Protocol (NFTRP) Mechanism for Unequal Chain Length in Wireless Sensor Network. The major novelty of this work is that sensor nodes can send their data to alternate path during a fault. The energy efficient can be achieves using clustering protocol for routing. The subordinate for each cluster help to tolerate faults occurred in the proximity. The cluster head nodes in proximity propagate aggregated data to base station. The simulation results show that the present approach yields better performance than the existing methods. It has observed that the proposed protocol NFTRP has better energy utilization than existing EE-LEACH and FTREEP protocols. The NFTRP protocol also has better packet delivery ratio than FTEERP.
