Reducing Energy Consumption in Mobile ad hoc Networks Using Energy-aware Routing Algorithm Based on Multiple Routes

Today, reducing energy consumption is one of the most important design criteria of routing algorithms in mobile ad hoc networks. Mobile ad hoc networks are self-organized networks and include mobile sets which have been connected to each other via wireless connections. Energy of the nodes in ad hoc networks is supplied from battery. Since, the battery capacity is limited and there is no possibility of replacing or re-charging; energy loss of a node will affect not only on that node but also on its ability to lead the packets and consequently on network lifetime. In ad hoc networks, the rate of nodes displacement and movement is very high and excessive use of a node and its movement result in network division. In this article, an energy-aware routing algorithm is presented which increases network lifetime by minimizing energy consumption in the route from source to destination. In the proposed method, traffic is distributed among the routes using multiple routes and due to the weight of each route, so the traffic of nodes with the above mentioned usages is reduced.
