Evaluation of Trust and Revocation of Malicious Nodes in MANETs

Abstract

Mobile adhoc network (MANET) is formed by a set of mobile hosts which communicate via radio waves within the transmission range. Manets are wireless communication where nodes can freely move within the network. Manets operate in the absence of base station and central access point. Applications of Manets are different in various areas. Manets are famous because of its self configuring, wireless and dispersed. The main factor in Manet is its security. The features of Manets are actually nontrivial problems to the security design in Manets. Manets are vulnerable to attacks due to the absence of the centralized control, dynamic topologies. Hence it’s very important to protect Manets from various types of attacks and revocate the certificate of the malicious nodes.
