Intelligent Secured Fault Tolerant Routing in Wireless Sensor Networks Using Clustering Approach

In wireless sensor networks, the nodes are deployed randomly over a large geographical region for monitor and collect the data. These nodes are powered by battery and are impossible to get recharged after deployment. Thus, minimizing the energy consumption of the sensor nodes is a challenging issue in wireless sensor networks for guaranteeing the network s lifetime. Clustering is one of way to maintain an effective topology in wireless sensor networks in order to reduce the overall network s energy consumption. In wireless sensor network providing an energy efficient in sensor networks is more difficult due to lack of infrastructure in the predicting the location of each node in the network. In this study, researchers propose a new clustering scheme that optimizes energy using a clustering algorithm to enhance the performance of the network. In addition, fault tolerant routing is proposed in this research by considering cluster sub heads. Therefore, we have modified the AODV with a clustering and security features to reduce the number of nodes involved in routing and to avoid denial of service attacks. We compare the performance of this proposed protocol with AODV with respect to distance and energy metrics. This modified AODV with clustering improves the QoS in terms of packet loss, packet delivery ratio and end-to-end delay.
