| 摘 要： | 针对已有移动自组网容量、延迟闭解分析在移动模型方面的局限性，提出了新的概率理论框架，将无记忆的独立同分布移动模型推广至更为真实的满足特定记忆条件的随机路径点移动模型，解决了局部移动方式带来的一系列复杂概率描述问题.对多副本两跳中继算法进行了研究，得出该中继模式下基于随机路径点移动模型的移动自组网的容量、延迟上限的精确闭解表达式.仿真实验结果证明了该概率理论框架的有效性及闭解表达式的准确性.

| Abstract: | To overcome the limitation of mobility models for the closed-form analysis of capacity and delay in mobile ad hoc networks, the paper introduces a new probability theoretical framework in order to extend a memory-less independent and identically distributed mobility model to a more realistic random waypoint mobility model with certain memory, which solves a series of complex probabilistic problems caused by the way of local move in the random waypoint mobility model. The two-hop relay algorithm with packet redundancy is also investigated and then the accurate closed-form expressions of capacity and delay are obtained. Simulation results demonstrate the efficiency of the proposed probability theoretical framework and prove the accuracy of the closed-form theoretical expressions. |
