摘要:

为了得到混合移动自组织网络的网络容量,对网络结构、节点移动规律、数据流进行了建模与分析,得到了适用于任意基站覆盖区域、任意(平稳遍历)移动过程、任意调度和路由算法的平均网络容量的解析表达式. 稳态分布为均匀分布的情况下,得到了该上界的极限,并对结果进行了数值分析,给出了极限网络容量、节点密度、基站覆盖率之间的关系.

关键词: 延迟容忍的混合移动自组织网络, 网络容量, 最优节点密度

Abstract:

Network capacity region is an important character of mobile Ad hoc networks. Using cell-partitioned model, an expression of upper bound of delay-tolerant hybrid mobile Ad hoc network is deduced regardless of coverage of base stations, types of mobile process, scheduling and routing algorithms. The limitation of the upper bound is derived, Analysis of the limitation of upper bound is carried out when the steady-state follows even-distribution law. The relationship among limitation of capacity, the node density and coverage of base station is analyzed.

Key words: delay-tolerant hybrid mobile Ad hoc networks, network capacity, optimum node density
