Ad hoc network is a kind of job without fixed structure environment of self-organization wireless mobile network. Network of each node works as hosts and a router, its node to move on without network infrastructure, Ad hoc network circumstance can rapidly networking. Therefore suitable for military or some special applications, it has a broad prospect of application.Based on elaborating Ad hoc network based on the structure of the network, it emphatically the key technology -- routing technology is studied. One purpose distance vector routing protocol (sequence DSDV) is a kind of table driven active routing protocols, each node periodic and adjacent node exchange destination node, hop count and purpose, achieve serial number etc routing information routing table updates of purpose. Dynamic source routing protocol DSR use resource routing algorithm, which consists of two parts:the mute discovery and routing maintenance. While sending data if the destination node routing already in the routing table is directly send data, or start routing discovery process, when new routing is discovered, the buffer within the entries subsequently updates. According to the needs AODV distance vector routing protocol is DSDV DSR and comprehensive, borrowed DSR road by discovery androuting maintenance based program as well as in DSDV jump routing and serial number and periodically update information usage establish routing. Based on the analysis of the advantages and disadvantages of three kinds of routing protocols, considering the battlefield environment, using OPNET simulation software, to AODV, DSDV DSR, three routing protocols are simulated, and selected delay, package delivery rate, routing overhead as parameters, of the simulation results for a detailed analysis, in order to find a suitable for battlefield circumstance network routing, for further research on digital battlefield Ad hoc network provides reference and.
