Energy Efficinet Intrusion Detection System in mobile ad-hoc networks

Information Techology

The main characteristics of ad hoc networks are the lack of predefined infrastructure and the dynamic topology. Usually, security in ad hoc networks is handled through intrusion detection system. Each node has its own IDS (intrusion detection system). If all node start its IDS for detection then overall energy consumption will increase as well as lifetime of ad-hoc network will decrease. To balance the resource consumption among all nodes and prolong the lifetime of MANET, nodes with the most remaining resources should be selected as the cluster head. However, there are two main obstacles in achieving this goal. First, without incentives for serving others, a node might behave selfishly by lying about its remaining resources and avoiding being selected. And second, any node joins or leaves the cluster how detection service will carried out. To address the issue of selfish nodes, presenting a solution based on reputation and impact factor value in time shared fashion. For detection watchdog intrusion detection and prevention technique is used.
