Secure Congestion Adaptive Routing Using Group Signature Scheme
In this paper security concerns in load balanced congestion adaptive routing (LBCAR) algorithm in mobile ad hoc network has been taken care of by using new concept of group signature for secure communication in the network. The performance of network using secure packets in the network has not degraded and has provided security. The proposed algorithm determines congestion status and weakest node of the route with low traffic load density and maximum life time is selected for packet transmission. The results show that it is promising to apply group formation strategy in MANET. The performance of LBCAR algorithm has been analyzed and compared with AODV and DSR and has resulted in reduced packet loss with increased throughput and packet delivery ratio.
