Energy based adhoc on-demand single and multipath routing for energy and overhead optimisation

In a typical adhoc network, mobile nodes come together for a period of time to exchange information. While exchanging information, the nodes may continue to move, and so the network must be prepared to adapt continuously. Sensor nodes are battery-powered devices, which have limited battery power and energy efficiency becomes an important parameter. After the deployment of sensor nodes in the network, it is not possible to replace each and every battery. So the most common method to achieve energy efficiency is, node transmits the data packets to its nearest neighbour which is at minimum power level, but this scheme minimizes only the transmission power within the node´s neighborhood and energy efficiency at the link level is only possible. With this method it is not possible to minimize the overall consumed energy and overhead of the network. So an analysis has been made and that results has been proved that instead of using low transmission power, only selected nodes are to be allowed to receive and process this routing request based on battery power of the node and that selected nodes are previously assigned by the sender node itself, by doing this the overall consumed energy and overhead of the network can be minimized. In this paper, both single and multipath is performed, and their performance is analysed based on energy consumption and overhead.
