Abstract: In mobile ad hoc network (MANET), most of the existing routing technique lags trusted way of communication among the mobile nodes. The control messages are also prone to the external threats. Also, the act of performing authentication of the nodes during each routing process causes increased overhead. Hence, in this paper, we propose a trust-based light weight authentication routing protocol in MANET. Initially, a multipath route discovery technique is utilised that selects the path with maximum packet success ratio as optimal path for data transmission. For each node in the chosen path, global trust value is estimated based on direct and indirect trust values of the node. If the trust value of any node is below threshold value, then it is authenticated using the secret sharing technique. This authentication technique enhances the reliability, redundancy and network lifetime. By simulation results, we show that proposed protocol improves the reliability and security of routing.
