A Hybrid Secure and Energy Efficient Cluster Based Intrusion Detection system for Wireless Sensing Environment

Rapidly expanding application areas of wireless sensor networks (WSNs) that includes critical civilian and military applications intensifies the security concerns especially in hostile unattended environments. WSNs are comprised of huge number of energy constrained nodes whose battery replacement or recharging is a challenging task after their deployment. Therefore, in order to keep the network alive, communication between the nodes must employ load balancing techniques. This constrained nature of nodes makes it crucial to consider both energy efficiency and security in data collection approaches for WSNs. In this present work, we develop a Integrated IDS scheme (IIS) that integrates the concept of clustering along with and Digital signature. For heterogeneous systems, cluster-based protocols perform best as they work on divide and conquer strategy. In order to safeguard the transmitted data, a secured, lightweight digital signature scheme that employs symmetric cryptography is used. The proposed IDS scheme is compatible with the WSNs characteristics and is capable of efficiently protecting the network from wide range of security threats. The simulation as well as the theoretical results shows that the proposed scheme has noticeable improvement in energy consumption and overall security.
