ICT distribution-based contact model for delay tolerant networks

  • 摘要: 在容迟网络中,掌握节点之间的接触间隔时间(ICT)的特性,能够为网络性能分析、路由协议设计以及算法优化等研究提供理论指导和帮助,但目前的ICT模型往往缺乏普适性.通过对节点运动做出一般性假设,基于可靠性数学方法,给出了一个基于ICT分布的接触模型——IDCM.该模型证明了两个移动节点之间的ICT服从指数分布,且指数分布的参数仅与两个节点的历史接触次数和累积ICT有关.在随机方向(RD)移动模型、随机路点(RWP)移动模型、北京市出租车网络、口袋交换网4个数据集上进行了仿真验证,并与基于统计拟合参数的指数分布模型进行对比.仿真实验结果表明,IDCM能够准确反映节点对之间的接触间隔时间分布,且模型准确性优于基于统计拟合参数的指数分布模型.
