The routing protocol design with security and energy efficiency is a challenging task in mobile ad hoc network (MANET). To overcome this challenge, we propose an energy-efficient secured routing protocol. The objective of our work is to provide a secured routing protocol, which is energy efficient. To provide security the proposed technique allows each communicating node to monitor reputation factor, suspicion factor and contingency of threat to compute the degree of its vulnerability. The

... y efficiency in optimized link state routing (OLSR) routing protocol is increased by generating new parameters and considering the energy of nodes. Based on the energy efficiency and security parameters the optimal route (multipoint relay) was selected. This approach uses less energy and secured compared to other energy models. The simulation result exhibits that the proposed multi objective Ant Lion Optimizer (MOALO) outperforms other state of art with respect to the performance metrics like energy consumption, Delay, throughput and network lifetime.
