摘要:在分析现有移动模型性能的基础上,针对远洋渔船机会网络中节点运动作业时的特点,提出了一种符合远洋渔船移动特征的平滑转弯半马尔科夫移动模型(Smooth Turn SemiMarkov Smooth Mobility Model,简称STSMS模型).从节点运动方程和平均稳态速率两方面进行了理论分析,并对节点运动轨迹和平均稳态速率进行了仿真验证.仿真结果表明,构建的STSMS模型能较好地反映节点的运动特点,并具有速率不随时间延长发生衰减的特性,适用于远洋渔船机会网络的模拟仿真.



Abstract:Based on the analysis of the performance of the classical mobility models and the characteristic in Ocean Fishing Vessel Opportunistic Networks (OFVON), this paper presents a Smooth Turn SemiMarkov Smooth Mobility Model (STSMS). An analysis is also made of the equation of node motion and stationary average speed, and then the trajectories and stationary average speed of nodes are proved by simulation. The results of simulation show that STSMS the established STSMS well coincides with the characteristic of node mobility and has not the attenuation characteristics as time increases. Thus,STSMS model can be applied to simulation of OFVON.
