摘　　要：针对ad hoc网络的拓扑可变性,设计了一种基于表驱动的网络路由协议。该路由协议中的每个节点维护一个拓扑集和一张到其他节点的路由表,当网络的拓扑结构变化时,各节点实时更新网络的拓扑项和路由表。同时在FPGA上实现了一种基于有限状态机(FSM)的路由表管理。经验证,该路由协议可以快速响应拓扑的变化,路由时延低,硬件资源占用少且功耗小。Aiming at the topology variability of ad hoc network,a network routing protocol based on table driven was designed.Each node in the routing protocol maintained a topological set and a routing table to other nodes.When the network topology structure changed,each node updated the topology item and routing table in real time.At the same time,the routing table management based on finite state machine(FSM)was implemented on FPGA.It is proved that the routing protocol can respond to the change of topology quickly,with low routing delay,less hardware resources occupation and less power consumption.
