Group mobility model creates global movements, but with certain groups of nodes staying close to each other.
      
Group mobility model describes group movement as well as individual node movement inside groups.

  group mobility models
Under a random behavior, the model provides a unified approach to describe many different mobility models including entity mobility models and group mobility models.
      
As expected, the random mobility model has a higher link change rate than the group mobility models.
      
Hence, the need arises for developing efficient and realistic group mobility models.
      
However, in this case different group mobility models can have different effects on the change rate.
      
In some scenarios, it may be better to use group mobility models, where the nodes move in groups rather than independent of each other.

Nowadays, there is tremendous research work about Ad Hoc networks, in which many efforts focus on the performance analysis and protocol behavior design. The selection of the most realistic and the most easy-to-implement mobility model is very crucial for the validity and feasibility of research. This paper presents several mobility models commonly used in Ad Hoc networks, representing mobile nodes whose movements are independent of each other and several mobility models that represent mobile nodes whose movements are dependent on each other. Through analyzing their associations and differences, we describe the application environments of each model and the qualification conditions of selecting models. The above work is expected to contribute to selecting mobility models or the design of new mobility models in order for the protocol design and planning of the network.

现今对AdHoc网络的研究如火如荼,基于AdHoc的系统性能分析和协议行为设计逐渐成为研究的主流。如何选择最贴近实际、最易实现的移动模型是研究的基础,也是成功的关键。本文总结了几种常用于AdHoc网络中的移动模型。其中有节点之间独立移动的实体移动模型,也有由一些节点组成一个整体,按照一定的约束一起移动的组移动模型。本文通过分析各种移动模型的关联和差异,给出了它们各自的适用范围以及选择的依据条件,为今后在协议设计和网络规划等要求下的移动模型的使用和新的移动模型的设计实现打好了基础。

战术互联网是AdHoc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:ConfinedGroupMobility),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:ReferencePointGroupMobility)进行了比较。仿真表明,不同的组移动模型对AdHoc网络的性能仿真将产生较大的影响。
