层状Ad Hoc网络的信息传播路由算法研究

讨论了层状移动AdHoc网络的一个信息传播路由算法和基于半马尔可夫过程的节点移动跟踪模型,通过该路由算法可以有效地解决层状子网络间的通信和信息交换。通过路由算法得到的中继节点的移动跟踪模型和计算机仿真,分析了层状移动AdHoc网络的传播性能和路由开销,并得出:当 0≤ρ≤ 1时,层状AdHoc网络的传播性能显著地受到移动呼叫率ρ的影响,当ρ>1时,层状AdHoc网络的传播性能主要取决于移动网络的节点总数、节点移动速度和加速度的结论。

Information transmission routing algorithm for hierarchical mobile ad hoc networks

An information transmission routing algorithm and a node mobile tracking model based on semi-Markov process for hierarchical mobile ad hoc networks were investigated. This algorithm can be applied to the communications and information exchange between the hierarchical sub-networks efficiently. By the mobile tracking model of relay nodes deduced from the routing algorithm and computer simulation, we analyzed the transmission capacity and routing cost of hierarchical mobile ad hoc networks and arrived at the conclusion that, the transmission capacity is influenced by the mobile calling ratio ρ when 0≤ρ≤1 and, in the other hand, influenced by node’s totality, mobile velocity, and acceleration when ρ>1.
