SAAD: SECURE AGGRIGATION WITH ATTACK DETECTION IN WIRELESS SENSOR NETWORKS

Abstract Over the last decade relaying on WSN increased tremendously and WSN are used extensively in many applications like urban sensing, forest fire prevention, and military surveillance. These networks are formed to sense medium and to take the decisions based on the sensed information. Making these kind of networks reliable is essential and providing security is challenging task since it is difficult to Identify the compromised nodes in the network, and evaluating the false data injected by compromised nodes. Many researchers proposed different algorithms for identifying compromised nodes but they did not address the impact of false data generated by the compromised node and reliability of the network. In this paper we propose a secure aggregation with attack detection (SAAD) algorithm which discovers the compromised node, avoids the impact of data contributed by these nodes and renovate the network to provide the Security and reliability in WSN.
