Research And Desigh For Routing Protocol In Mobile Ad Hoc Network

Mobile Ad hoc network is a kind of dynamic, self-organization and multi-hop wireless network which has no basic facilities to support; And because of these characteristics, Mobile Ad hoc network has broad application prospects in the field of communication, earthquake relief, traffic management and environmental monitoring.In this article, considering the characteristics that mobile nodes in Mobile Ad hoc network are with limited energy, an energy-based balancing AODV routing protocol is proposed basing on AODV (Ad hoc On - demand Distance Vector Routing) routing protocol; In improved routing protocol, the received routing requests are forwarded or discarded in accordance with the current node's residual energy level, so the low-energy node are delayed in accessing the route, to achieve a balanced network with each node energy consumption balancing. The simulation results show that improved protocol compared with the original agreement, save node energy resources, improve the network transmission performance and prolong the survival time of the network.Considering the current load of mobile nodes, that is, the current cache queue length of the nodes, a load-based balancing AODV routing protocol is proposed; In the improved protocol, the received routing requests are forwarded or discarded according to the current node's current load level, so the high-load node are delayed in accessing the route; Comparing to the original AODV routing protocol, the improved protocol improves the network transmission performance and extended the survival time of the network; Finally, the rationality and correctness of the improved method is verified by simulation and analysis.
