Secure Routing Protocol to Mitigate Attack by Optimized Public Key Selective Encryption on AOMDV Algorithm in MANET

Abstract A Mobile ad-hoc network (MANET) is highly efficient to provide network services. Due to the dynamic behavior of the network, routing protocols have some design issues that affect network performance. The proposed work is based on optimal route finding and detects a link failure to maintain the route between a source and destination node for media file transmission. Ant Colony Optimization (ACO) with Ad-hoc On-demand Multipath Distance Vector protocol (AOMDV) detects a link failure and gives improvised quality of service (QoS) with local convergence while multimedia file transmitted in MANET. To provide global convergence in network swarm intelligence based GWO algorithm is used. During video files transmission Op-PKSEA algorithm shows increased through put up to 30%, packet delivery ratio up to 15% and minimize the channel load to 18% and end to end delay is minimize up to 20ms. Op-PKSEA algorithm concerning the parameters as mobility, number of nodes and packet size. The Op-PKSEA algorithm protocol maintain loop-free routing, mini mum control overhead, QoS provisioning for minimum latency, end-to-end delay, maximize packet delivery ratio and throughput.
