选取合适的移动模型对于移动自组网仿真非常重要。不同的移动模型对自组网的性能仿真将产生较大的影响。现实世界中可移动设备大多由人携带或控制,通过对现有自组网移动模型的研究比较,针对节点移动受到人自身意识和周围环境吸引的社会化特性,提出并建立了动态兴趣引导移动模型。仿真结果表明,动态兴趣引导移动模型表现出移动轨迹随着时空变化的聚散现象,适合人控移动设备构建的自组网仿真。
Realistic models for node movement are essential in simulating mobile ad hoc networks. The various mobility models will affect the performance of Ad Hoc network in different ways. Based on the observation that human-like motion occurs frequently in ad hoc networks, a novel constrained entity mobility model Dynamical Interesting lnduced Mobility Model (DIIMM) was proposed. The simulation shows that the trajectory of nodes presents the convergence-disperse phenomenon based on human decisions and socialization behavior. The results indicate that DIIMM can be used in simulations to produce human-like network scenarios.
