Fault Tolerant Event Detection in Distributed WSN via Pivotal Messaging

To mitigate the problem of loosing data, which can be very crucial to prevent environmental disasters, we proposed a fault?tolerant event detection algorithm in a distributed environment. We considered the data loss because of node failure in?sensor network due to some technical fault or energy issues. This algorithm works by backing up the data of cluster heads?at some secondary nodes. If the secondary node that is backup cluster head notices the failure of primary or vital clusterhead,?it will inform this to all non cluster-head nodes through pivotal messages. Subsequently, backup cluster-head will?start working as vital cluster-head with new backup cluster-head. We have taken all parameters with the promising optimal?use of energy. We have compared our results with the existing Dynamic Static Clustering Protocol (DSC) and fault toleran?Dynamic Clustering Protocol (FT-DSC). We have compared results on the basis of various parameters like energy?consumption over time, number of data packet transmission and network life time based on network remaining energy.
