A Secure solution for routing in MANET

This paper presents wireless ad hoc network which communicate with each other by forming a multi-hop radio network and maintaining connectivity in a decentralized manner. The principle behind ad hoc networking is multi-hop relaying, which means that the messages are transmitted by the other nodes if the target node is not directly reachable. For communications with the nodes which are not within the radio range of nodes to the route must be taken from the intermediate nodes to reach the destination. These intermediate nodes acts as router which receives the data coming from the source and forwards the data to destination This situation is of potential security concern as there can be attack possible by the intermediate node like Man in Middle Attack. Hence an authentication procedure is be used for authenticating the mobile nodes to each other and proper encryption decryption mechanisms is also employed. Also intermediate nodes can act as malicious nodes which must be removed or alternate route should be found which does not include nodes already used in previous route. Thus we have developed architecture will provide secure routing mechanism which will use two kinds of encryption techniques. Then the possible attacks are being analyzed and removed from the architecture.
