Based On The Geographic Location Of The Power Of Ad Hoc Routing Protocol Research

An Ad Hoc network is a new network interconnection technology, it is different from Internet.The nodes in Ad Hoc network can communicate with each other without infrastructure which was set in the past time.On the other hand.Its mobility make it different from the traditional Wireless Sensor Network,this make it can be applied to a wider area,such as Military Communication,Aid after disasters and more.There are many types of routing protocols. Many routing protocols are conbined by topological structure routing protocols and geographic location routing protocols.they are derived from the protocols which are based on topological structure and geographic location.They take the advantages of two kinds of protocols,keep away from their disadvantages,At last,they become the stable and high efficient routing protocals. In this text, we propose a routing protocal(G_AODV) which conbined by topological structure and geographic location,and it is based on AODV protocal and GPSR protocol.Then,we propose power-aware Ad Hoc on-demand distance vector routing based on geographic location(PG_AODV)routing Protocal,which is based on G_AODV routing protocal.In Ad Hoc routing protocals,power-aware protocals are the important research topic all the time.In PG_AODV routing protocal,it takes the received signal power as and relative motion between the nodes to determine whether the link path into the dangerous state.Than using it to help to build and maintain routes. In the maintenance phase, when link gets into the dangerous state, PG_AODV finds a alternative route,before the old routing complete falling,realizing the seamless switching between the old and new routing.The paper gives the simulation experiment on the four kinds of routings,the results indicate that G_AODV protocol is more than AODV at routing failure times, packet delivery ratio, average end-to-end delay. Compared with GPSR protocol,int the nodes lower speed case,it is good at routing delay. PG_AODV is based on G_AODV,It is better than G_AODV in all aspects. Compared with GPSR protocol,It is better than in end-to-end delay.In other aspects,it is near to GPSR.
