Robust Aggregation Mechanism in WSN for Mitigating Attacks

Abstract

Wireless Sensor Network (WSN) is a collection of sensor nodes connected to base station which is characterized by many to one communication. Many sensor nodes will send data to base station making it many to on communication. The sensor nodes can act as sender and receiver of data as the data is sent to base station through intermediary nodes. The nodes are resource constrained as they are deployed in hostile environment or environment where resources are limited. The nodes are expected to participate in sensing or surveillance. WSNs are widely used in civilian and military applications for sending data and surveillance. As WSN is becoming increasingly popular, security needs to be provided in the network as the nodes are vulnerable to various attacks. Since the nodes are energy constrained, it is very useful to use some aggregation technique in order to reduce communication overhead and also energy consumption. Recently Roy et al. focused on aggregation in WSN for filtering out the impact of attackers on the network. Their focus was to use aggregation in WSN in order to reduce communication overhead and reduce the impact of attacks on WSN. In this paper we implement a variant of protocol that takes care of secure communications over WSN besides reducing energy consumption and mitigating attack impact. The simulation results are encouraging
