ABSTRACT
In a dynamic Wireless Sensor Network fault occurring in sensor nodes are common due low-cost sensors used in WSNs, deployed in large quantities and prone to failure. A wireless sensor network can get separated into multiple network connected components due to the failure of some of its component nodes that is called a “cut”. Cuts are group of failure nodes. An algorithm is proposed for detection and prevention that allows (i) every node to detect when the connectivity to a source node has been lost, and (ii) one or more nodes (that are connected to the neighbour node after the failure nodes) to detect the occurrence of the cut using nearest neighbours. (iii) Path selection using neighbour nodes. In this paper we have implemented NNS algorithm for detecting failure nodes by neighbours and avoiding failure paths for transmission in dynamic wireless sensor network. The RCDPWSN system can very easily prevent from data lost using rerouting.
