Wireless Communication

Abstract

Wireless Sensor Network consist of several autonomous sensor nodes that are capable of some sort of sensing power. Since the sensor nodes are placed in harsh environments, WSN is vulnerable to various types of attacks. Hence security is very important for various WSN applications. Most of the energy efficient routing protocols for WSN are hierarchical or cluster-based routing protocol. The important concern of routing protocols of WSNs is to balance the energy consumption as well as maintaining the security level. Many secure cluster-based routing protocols have been proposed to achieve the above concern. In this paper, an intrusion detection system in a clustered network model is proposed, that addresses the problem of performance and security of existing protocols in WSN. It makes use of the concept of clustering architecture of WSN, key management techniques, and trust computation methods.
