A Secure AODV Routing Protocol with Trust Algorithm in Mobile Ad-hoc Network

In wireless sensor network or mobile ad-hoc network, numbers of sensor or mobile nodes are present that communicate with each other. The data is exchanged between these nodes, for this many routing algorithms are used that determine the path, distance etc. of the network. The process of finding the path between the nodes for information transfer is termed as routing. As per literature studied it was concluded that the most of the routing protocols such as AODV, DSDV, DSR etc. do not focus on the security of network. As per comparison, AODV routing protocol is better than the other protocols on the basis of performance metrics like throughput, PDR, packet loss etc. The security is one of the key factors that should be considered while transferring the information. Traditional protocols work on the basis of the distances between the nodes, trust value, bandwidth, and throughput etc. Security of the data was not considered anywhere. So in this work, a new algorithm is proposed that will take security of the data in account along with it the trust mechanism approach is updated. On the basis of both direct and indirect trust values, node to node distance is calculated. After finding the route, the security of the data is maintained by introducing key concept. This encryption of data before sending it to the destination prevents it from unauthorized access. From the results obtained it is concluded that this proposed algorithm is efficient than the traditional routing algorithms as the security of the network is increased. So we can say that this paper improved the security of AODV routing protocol with trust calculation and key concept.
