Minimum Energy Node Disjoint Multipath Routing for Ad-Hoc Networks

In order to reduce routing load and route coupling,a new scheme the reliable minimum energy node disjoint multipath routing with directional antenna(RMENDMRDA),is presented.The scheme selects the minimum sector cover to save energy consumption using optimal beamwidth selection(OBS).After this,RMENDMRDA utilizes link reliability selection(LRS) to select minimum aggregated energy node disjoint multipath.Theoretical analysis showed that RMENDMRDA has higher reliability and lower routing overhead.Simulation results showed that compared with STPS(source transmit power selection) and NDMR(node disjoint multipath routing),the packet delivery ratio of RMENDMRDA increases by about 18%,routing load reduces by 24% and energy consumption saves by about 8%.
