With the rapid development of wireless communication technology and computer technology ， people wish to get reliable data communication service any time and any where . traditional network can not supply communication service if the whole network need to move because the network devices are fixed by wires and can not move . so , ad hoc network comes . it can provide mobile data communication service compared with traditional network . ad hoc is a network with plat structure and all the nodes is equal . all the nodes need provide relay . but not all the nodes will provide relay and the performance of plat structure is poor in large scale . so the wireless mobile self - organized network adopts a two - level structure by referencing the cell mobile communication system . wmsn uses wireless routers to construct network . it can provide wireless access , relay services to users 考虑到不是所有的站点都愿意提供中继服务及平面结构的局限性（在网络规模较大时性能会很差） ，本课题的无线移动自组织网络参考了蜂窝移动通信系统的特点，是一种具有两级结构的网络。使用专门的无线设备? ? “无线路由器”构成具有用户无线接入、无线组网和路由功能的无线互连网络，为移动用户提供无线接入、路由和中继服务。 ieee802 . 11b可以提供很高的通信速率，可以提供很好的接入性能，并且支持ieee802 . 11b协议的设备正成普及的态势，因此成为我们所选择的链路层协议。
Providing an extremely flexible method for establishing communications , the mobile self - organizing network has potential applications in both military and commercial communications . based on the gsm wireless communication system and the ad hoc network , there are two level hierarchies in the mobile self - organizing network : wireless routers and wireless hosts . wireless routers perform the function of constructing routes , forwarding data , and locating mobile hosts 结合蜂窝式无线移动通信系统和adhoc网络的特点，本文设计了具有两级网络结构的无线移动自组织网络系统，使用专门的无线设备? ? “无线路由器”构成具有用户无线接入、无线组网和路由功能的无线互连网络，为移动用户提供无线接入、路由和中继服务。
This paper introduces the routing scheme of the wireless router : include centralized mobile routing technology and dynamic network routing protocol . the simulation model of the network routing protocol is also described , and the model ' s validation is verified . this paper will give a good reference to the routing implementation of the wireless mobile self - organizing network system , and the building of the simulation model lays the foundation for the evaluating of the network performance 根据上述思想，本文介绍了无线移动自组织网络中“无线路由器”的路由设计方案，包括采用集中方式进行用户寻径的移动路由技术和用于维护网络拓扑的网络路由协议的设计，对网络路由算法进行了仿真模型的建立，并验证其有效性。
The wireless sensor network consists of a large quantity of sensor nodes whose power , calculation ability and bandwidth are so limited that traditional wireless routing protocol is not suitable for wireless sensor network , it is the key point to save power and prolong the lifetime of network in the research of wireless sensor network 由于无线传感器网络通常由大量密集的传感器节点构成,节点的能源、计算能力和带宽都非常有限,传统的无线路由协议不适合无线传感器网络。从而设计能够有效节约能源,延长网络生命周期的路由协议成为了无线传感器网络研究的一个重点。
The chinese national hi - tech program , wireless self - organizing network technologies and design has proposed a self - organizing algorithm - kernel tree routing protocol ( ktrp ) , which has resolved the problem of routing loop in ad hoc networks by a tree - shaped topology of wireless routers ( wr ) , furthermore , it has reduced the items of routing tables 863课题“无线移动自组织互联网技术及实验系统研制”中提出了一种分层的自组织算法? ?核心树路由协议ktrp ( kerneltreeroutingprotocol ) ,通过无线路由器( wirelessrouter , wr )的树形逻辑拓扑解决了adhoc网络中路由环路的问题,并减少了wr的路由表项。
Thus , it can be easily deployed without the use of any existing network infrastructure and make mobile users more convenient to access it . motion is wmsn ' s main characteristic which cause dynamic variety of network topology . the wireless datalink status information sense scheme design introduced in this paper is developed for this specific environment . it mainly informes dynamic routing module to update dynamic routing information in time and improve its response time to dynamic variety of network topology 无线互联网与传统的有线互联网相比，其最显著的特征就是其移动性，因此无线路由器（ wr ）需要及时感知网络拓扑结构的变化，并根据发生的变化对动态路由进行调整，这要求能通过无线链路驱动进行相邻wr加入与离开的感知，主动及时地向路由模块通告无线链路通断等相关信息。
