移动自组网络是一种灵活的不依赖于固定基础设施的新型无线网络，生存性极强，且创建与移动极为方便的特点，使之弥补了蜂窝系统与有线网络的不足，在许多特殊情况下有着不可替代的作用。文中通过对Ad Hoc网络中OLSR链路状态路由协议的分析，在OLSR协议的基础上，通过修改OLSR协议单一的跳数度量方式，将节点的剩余能量作为度量的一个因素，并计算最终路由信息。通过仿真，证明该算法提高了分组投递的可靠性，减少了端到端时延，提高了网络的吞吐量。

网络移动性基本协议（NEMO BS）可用于整个移动网络的移动性管理。此协议为移动设备提供无缝的因特网接入能力，适用于车辆间通信、灾难救援等场景。然而，NEMO BS并没有解决其引入的多三角问题，这一点将大大影响协议的通信效率。本文提出了一个新的解决NEMO网络中多三角路由的优化方案。在同一个接入点下的移动路由器将组成一个无线自组织网络域，在此自组网域中，所有的内部消息将按照最优链路状态路由（OLSR）协议传输。移动路由器将根据其当前的因特网接入能力而被分为根路由器与非跟路由器两类，根路由器将作为其他非跟路由器的网关，非跟路由器则需要保存根路由器信息列表，并根据相应的参数选择最佳的根路由器。当NEMO与因特网通信时，被选作根路由器的移动路由器将建立双向隧道，直接将数据包发送到目的家乡代理，从而省去中间节点的多重封装。此方案可以有效避免多三角路由，从而优化路由协议。最后，经OPNET的仿真结果证明，此方案可以有效减少传输消息的封装级数，降低传输时延，并提高整体网络的通信效率。

Network Mobility Basic Support Protocol (NEMO BS) is a protocol proposed for the mobility management of mobile networks. It provides a group of mobile devices with seamless Internet connectivity, and it can be used in the vehicle communication and disaster rescue. However, NEMO BS cannot deal with the problem of pinball routing in the nested mobile network which would heavily increase the communication cost. This article puts forward a novel route optimization solution to solve pinball routing. The mobile routers under the same access router compose an ad hoc network. In the ad hoc network all messages are routed by Optimized Link State Routing (OLSR) protocol. The Mobile Routers will be divided into Grounded Mobile Routers (G-MR) and Non Grounded Mobile Routers according to their connectivity to the Internet at a moment. Ground Mobile Routers should do the works as a gateway for all of the Non Grounded Mobile Routers in the ad hoc network, and the Non Grounded Mobile Routers will keep
