摘　　要：AdHoc网络是一种移动无线网络,具有网络结构组织灵活等特点。优化链路状态路由(OLSR)协议是专为适应无线自组织网络需求并对纯链路状态算法进行优化而形成的一种标准化先验式路由协议。针对组网终端在系统运行中网络拓扑临机改变导致网络中存在多跳寻址的需求,设计采用一种基于OLSR协议的分布式多跳自组网技术。该技术通过分布式网络感知综合考虑网内成员连通性及转发意愿,并根据多点中继节点(MPR)集选择算法分布式自适应选取网络内中继节点,为用户提供多跳寻址能力。通过OMNET++仿真平台验证了其可行性。As a mobile wireless network,Ad Hoc network has the characteristic of flexible network structure.Optimized Link State Routing(OLSR)protocalis a standard apriori routing protocol designed to meet the requirements of wireless Ad Hoc network and optimize pure link-state algorithms.A distributed multi-hop Ad Hoc networking technology based on OLSR protocol is designed to solve the need of multi-hop addressing due to the change of network topology.The technology takes into account the connectivity and forwarding intention of the network members through distributed network perception,as well as selects the relay nodes in the network according to the distributed adaptive Multi-Point Relay(MPR)set selection algorithm,which provides the multi-hop addressing capability for users.The feasibility of the technology is verified by the OMNET++simulation platform.
