Abstract:

For the stable communications of Ad Hoc network, we optimized the AODV-FABL(Ad-Hoc  On-demand Distance Vector Fast Adaptive Backup Local） protocol, which is an improved routing protocol(AODV-OFABL：AODV-Optimize Fast Adaptive Backup Local). The HELLO message of the AODV-FABL is modified. The delivery ratio of packet and nodes mortality were reduced. Based on the current army's structure and reality warfare, we establish the special warfare, field warfare and urban warfare model. Using NS3 simulation software, we obtained the best combation between the model with the route. The results show that AODV-OFABL protocol is more suitable for using field warfare. When stayed for 60 s, the delivery rate of packet reached 97%, with the average delay down to 320 ms.

Key words: Ad Hoc, routing protocol, Ad Hoc on-demand distance vector-fast adaptive backup local （AODV-FABL）, AODV-optimize fast adaptive backup local （AODV-OFABL）
