摘要:群组移动模型是对群组终端在泛在网条件下进行移动性管理的基础。针对泛在网异构性特点,基于Lennard-Jones势能模型,提出了泛在网条件下群组力移动模型,通过引入分子间作用力的概念,对群组内各个终端的运动状态进行描述,较好地刻画了群组的移动特性;同时,通过对该模型进行Lyapunov稳定性分析,得出群组在运动过程中,各个终端运动状态趋于一致,系统趋于稳定。理论证明该模型可为群组终端在泛在网络中移动时,提供一种有效实施移动性管理的方法。
Aiming at the mobility model forces, the mo Lyapunov stab stable. It is th Group mobility model is the foundation of the mobility management in ubiquitous network. heterogeneous characteristics of ubiquitous network, this paper proposes a group force based on the Lennard-Jones potential function. By introducing the concept of intermolecular tion state and mobile features of terminals are both formulated. Meanwhile, by analyzing its ility, it is shown that the terminals will reach agreement and the system is asymptotically eoretically proved that this model can provide a feasible method for mobility management of the group moving in the ubiquitous network.
