提出了一种 DTN 网络中基method based on birth and death model)。在节点数据传输过程中,根据数据传输量计算得到各个连通链路采样时刻于生灭模型的节点运动模式检测方法(MMD-BDM
mobility model detection的信道容量,在本节点构建以信道容量构成的三维时变连通矩阵,并在此基础上推导出基于边连通的节点连通性由转发策略。最后,将该运动模式检测方法应用在喷射路由(SWR
spray and wait routing)和随机网络编码路由生灭模型,然后分析节点连通边的生灭特征并以此判断节点的运动模式,以优化 DTN 网络消息投递过程中的路(RNCR

A mobility model detection method based on birth and death model (MMD-BDM) in DTN environment was proposed.It first computed the connected channel capacity of sampling times according to the data traffic during the data transfer process
and then constructed the time varying intercommunication metrics at local
which composed of channel capacity between local node and others.Based on these
the connection birth and death mode of nodes based on connected edges was deduced
and then the birth and death features of the connected nodes was analyzed to detect the mobility model
which used to improve the routing strategy during the packages deliver process.Ultimately
the mobility model detection method was put into use in spray and wait routing (SWR) method and random network coding routing (RNCR) method to experiment
the simulation results show that
it can improve the opportunity routing performance of the data deliver rate and transfer latency in DTN environment.
