A New Method to Reduce Energy Consumption in Manet Network Routing based on OLSR Protocol and Genetic Algorithm

Mobile Ad Hoc Networks (MANET) can be considered as a class of unstructured networks created by a number of autonomous wireless and sensor nodes. The inherent characteristics of such networks have made specific applications, such as multimedia transfer and challenging. Basically, the functionality of a node and very few resources directly affect the delivery of packets which depends on the quality of the selected route. Since the nodes in MANET get their energy and power from batteries or other end-to-end resources, the most important criterion to design an optimal system is energy conservation. The purpose of this paper was to increase the efficiency of the OLSR routing protocol by generating new parameters and considering the amount of nodes energy. In this method, the optimal route was selected based on the remained energy in the middle nodes, the distance between the nodes and the number of steps. Therefore, the present paper used a genetic algorithm-based approach for optimal routing in the OLSR protocol based   on the remained energy of each node. It used the weight factor which has been determined based 111on energy consumption combined with shortest routes. It considered the energy factor of each node in routing and selected the optimal route.
