Detection of selfish & malicious behavior using DTN-chord monitoring in mobile networks
S. A. Mariyam Benazir, V. UmaRani · 2016
In mobile network, data nodes are distributed among the clusters. Mobile ad-hoc networks (MANETs) are an encouraging solution to establish communication for emergency response action, which impose some challenges especially on routing. In MANET, the mobile nodes are non-compulsorily cooperating in order to work properly. This cooperation of mobile nodes is a cost-intensive activity and some nodes cannot cooperate in proper way that leads to selfish node and malicious node behaviors. Thus, novel and efficient method has been proposed to identify the selfish and malicious node in the network. The main aim of this paper is to identify and correct the selfish and malicious behavior of nodes and enhance the cooperation among nodes. It uses Delay Tolerant Network (DTN) to finds the selfish and malicious node by recording its negative response of transmission by destination node. Proposed model improves the security and efficiency of the overall network performance.
