Abstract: A Mobile Ad hoc NETwork（MANET） is a collection of wireless mobile nodes forming dynamical and temporary network without the use of existing network infrastructure or centralized administration.The big challenge exists in designing and implements its routing protocol.Based on its feature and application request,this paper provide a zoned MANET routing protocol,zoned by the distance to MinID node,with information of the basic network topology and node’s neighbors,protocol’s request delay and control overhead is descend to O（2R）.Simulation result shows that the protocol’s routing request delay and control
overhead is very low.

摘要： MANET是一种无基础设施支持的动态、自组织、多跳无线移动网络,为之设计适当的路由协议是一大挑战。该文在分析MANET特性及应用需求的基础上,提出了一种的分区MANET路由协议,该协议基于到最小ID节点的距离形成分区并维护简化的全局网络拓扑,通过巧妙地利用节点的邻接点信息使得路由请求的时间和通讯复杂度均降为O（2R）。仿真结果表明,该协议具有路由请求时延低,控制开销少的特点。
