摘　　要：路由协议是无线移动自组网(Mobile Ad Hoc Networks,MANETs)的关键技术之一。针对优化链路状态路由(Optimized Link SState Routing,OLSR)协议中的多点中继(Multipoint Relay,MPR)覆盖度对网络开销的影响进行了分析。OLSR协议与一般的链路状态协议相比,其采纳了MPR机制,一定程度上抑制了网络中广播控制信息的洪泛,从而降低了网络中的控制开销,但是这种机制是否影响到路由的鲁棒性是值得探讨的问题。基于此,设计了相应的MPR选择算法并进行仿真实验。结果表明,适当提高MPR覆盖度能加快路由的收敛。Routing protocol is one of the key technologies of MANETs(Mobile Ad-hoc Networks).The influence of MPR(MultiPoint Relay)coverage in OLSR(Optimized Link State Routing)protocol on network overhead is analyzed.Compared with the common link-state routing protocols,OLSR protocol adopts MPR mechanism to suppress the flooding of broadcast control information in the network to a certain extent,thus reducing the control overhead in the network.However,whether this mechanism affects the robustness of routing is worth exploring.Based on this,the corresponding MPR selection algorithm is designed and simulation experiments are carried out.The results indicate that increasing MPR coverage can speed up route convergence.
