Abstract

In a wireless sensor network the delivery of the data packet from source to destination may be failed for various reasons and major due to failure-prone environment of networks. This may happen due to the topology changes, node failure due to battery, exhaust or breakdown of the communication module in the wireless node and results in the link failure. This paper addressed the major problem of link failure due to the failure of the nodes in the WSN and with the aim of providing robust solutions to satisfy the QoS-based stern end-to-end requirements of communication networks. In this paper, we propose the new solution by modifying the existing extended fully distributed cluster-based routing algorithm (EFDCB). In this proposed algorithm the faulty nodes or nodes that are more prone to failure in the every cluster of the network get identified by exchanging data and mutually testing among neighbour nodes. When we established the path between source and destination these faulty nodes get excluded in the path selection process and more stable, less prone to failure path will be formed. The performance of this new modified fault-tolerant fully distributed cluster-based routing algorithm is evaluated by simulating it in NS2 environment. Simulation results show that it performs better than the existing algorithm and provide novel solution for fault detection and fault management along the QoS paths and achieves a high degree of fault tolerance.
