A Cluster Header Election Scheme Based on Auction Mechanism for Intrusion Detection in MANET

In this paper, we study the cluster head nodes election mechanism for cluster based intrusion detection in the presence of selfish nodes in Mobile Ad Hoc Networks (MANETs). To prolong the lifetime of all nodes, each cluster should elect a node with the most remaining energy as its cluster head. But, the selfish nodes may behave selfishly by lying about their remaining energy and avoiding being elected. We represent the existence of selfish nodes really has a bad effect on the lifetime of the networks and propose a solution based on auction mechanism. More specifically, we design a mechanism with the following attributes: First, the mechanism can always elect the most energy remaining nodes as cluster heads. Second, the mechanism can encourage the selfish nodes behave honestly by providing incentives. Simulation results show that our mechanism can effectively prolong the overall lifetime of Intrusion Detection System (IDS) in MANET.
