Abstract
Mobile ad hoc network termed as MANET is an adhoc network with self configuring mobile devices connected by wireless links. Currently, MANET had a greater impact on secured communication as it is a part of the ubiquitous network. Each node in the MANET is acting as a router itself. Routing in wireless ad hoc networks are vulnerable to traffic analysis, link spoofing, wormhole attacks and denial of service attacks as it is of infrastructure less and having highly dynamic topology. Anonymity mechanisms is used to protect the nodes against these attacks by concealing identification information of the nodes, links, traffic flows and network topology information etc. For a secured communication, secured routing and anonymity to the nodes is essential in adhoc networks. MANET security issues includes provisions and policies adopted to prevent and monitor unauthorized access to the network and to the data. Several efficient protocols are proposed specifically for MANET, from these, optimised link state routing protocol is suited for large and huge dense network. The current OLSR scheme assumes the nodes are to be trusted nodes and the anonymity is not achieved yet through OLSR. The proposed solution is for achieving anonymity and security in MANET by implementing four way handshaking between two nodes using Host Identity Protocol and integrate it with OLSR for secured routing. The technique expected to have a less message overhead by compared to classical flooding mechanisms and increase the security level with a preferrable bit rate. Overall, the technique provides anonymity and security in the MANET environment.
