Improving Energy Efficiency in MANETs by Multi-Path Routing

Some multi-path routing algorithm in MANET, simultaneously send information to the destinationthrough several directions to reduce end-to-end delay. In all these algorithms, the sent traffic through apath affects the adjacent path and unintentionally increases the delay due to the use of adjacent paths.Because, there are repetitive competitions among neighboring nodes, in order to obtain the joint channelin adjacent paths. The represented algorithm in this study tries to discover the distinct paths betweensource and destination nodes with using Omni directional antennas, to send information through thesesimultaneously. For this purpose, the number of active neighbors is counted in each direction with usinga strategy. These criterions are effectively used to select routes. Proposed algorithm is based on AODVrouting algorithm, and in the end it is compared with AOMDV, AODVM, and IZM-DSR algorithms whichare multi-path routing algorithms based on AODV and DSR. Simulation results show that using theproposed algorithm creates a significant improvement in energy efficiency and reducing end-to-enddelay.
