A leader based intrusion detection system for preventing intruder in heterogeneous wireless sensor network

Nowadays communication and data transmission among various heterogeneous networks is growing speedily and drastically. More number of heterogeneous networks are created and deployed by government as well as by private firms. Due to the distance, mobility, behavior of nodes in the networks and dynamic in nature, it is essential to provide security for all the networks separately or distributed. Various existing approaches discuss about the security issues and challenges for heterogeneous networks. In this paper a Leader Based Intrusion Detection System [LBIDS] is proposed to detect and prevent DOS as well as other attacks such as Sybil and Sinkhole in the networks by deploying the Leader Based Intrusion Detection System into access points in the networks. The proposed approach utilizes three core security challenges such as Authentication, positive incentive provision and preventing DOS. In addition to that it will do packet verification and IP verification for improving the efficiency in terms of detection and prevention against attacks in heterogeneous networks. The simulation of our proposed approach is carried out in NS2 software and the results were given.
