Routing Enhancement of MANETs using Hybrid Protocol Combined with PBO

Mobile ad hoc Networks (MANETs) show an astonishing qualities in the concept of networks which are used without wires. MANETs experience numerous communication medium restrictions such as constrained storage of memory and development of effectual routing protocols. Furthermore, multihop routing mechanism employed in MANETs gives rise to the contention in the channel and jamming within the network. This limits the effectiveness of the network which reduces the energy efficiency of the network and also lessens the routing performance of MANETs. Hence, the major matter in MANETs is to minimize the congestion and contention in order to enhance the routing mechanism. Hence, in this paper, a novel protocol is put into practice having an enhanced route discovery mechanism which is implemented in order to avoid the congestion during the routing. The proposed protocol chooses the route for the transference of information on the basis of load within the traffic on the node and then resets the route with the change in topology. The protocol is then integrated with the proposed algorithm Pollination Based Optimization (PBO) algorithm. This is an efficient technique for transmission that requires a link for longer period of time. The simulator used for the simulation of the work is Network Simulator-2 (NS-2). Simulation results have been carried out showing that the route optimization and enhancement in the route discovery using Pollination Based Optimization (PBO) algorithm.
