Fault Tolerant Multi Cluster head Data Aggregation Protocol in WSN (FMCDA)

WSN consisting of a large number of small sensors with low-power transceivers can be an effective tool for gathering data in a variety of environments. As sensor nodes are deployed in sensing field, they can help people to monitor and aggregate data. Researchers also try to find more efficient ways of utilizing limited energy of sensor node in order to give longer life time of WSNs. Network lifetime, scalability, and load balancing are important requirements for many data gathering sensor network applications. Therefore, many protocols are introduced for better performance. The efficient node-energy utilization is one of important performance factors in wireless sensor networks but besides this reliability is also an issue. In this paper, we proposed a cluster based routing algorithm to ensure high reliability such that the entire network becomes fault tolerant by the introduction of multi cluster heads.
