一种Ad Hoc网络组移动模型

战术互联网是Ad Hoc网络的主要应用，在该网络环境下，节点由于作战使命及建制的约束，移动节点常呈现出“组移动”的特征且组内节点通常分布在相对狭长的地带。针对战术互联网中移动节点的移动特征，提出了一种符合战术互联网环境的组移动模型：狭长的组移动模型（CGM：Confined Group Mobility），并从网络拓扑结构和对路由协议性能的影响两个方面与目前广泛采用的参考点组移动模型（RPGM：Refefence Point Group Mobility）进行了比较。仿真表明，不同的组移动模型对Ad Hoc网络的性能仿真将产生较大的影响。

Group Mobility Model for Ad Hoc Network

Tactical Internet is an important application scene of Ad Hoc network. Because of the task of battle and the restriction of organization, group mobility occurs frequently in Tactical Internet and nodes in group usually locate in a confined region. A group mobility model: Confined Group Mobility (CGM) model was proposed, which could answer for Tactical Internet environment. Moreover, CGM model with Reference Point Group Mobility (RPGM) model in network topology and the impact of two models on performance of routing protocol were compared. The results indicate that the various group mobility models will affect the performance of Ad Hoc network in different ways.
