混合Mesh网络容量分析

The Analysis on Network Capacity of Hybrid Mesh Network

网络容量作为衡量网络性能的重要指标,是Mesh网络研究的重点之一。在分析混合Mesh网络结构的基础上,将混合Mesh网络的流量模式分为小区内流量和跨小区流量,并根据不同的流量模式分别研究了相应的网络容量。混合Mesh网络的网络容量应为2种流量模式下网络容量之和。仿真分析结果表明,将用户节点分为多个小区可显著提高小区内流量的网络容量,配置多个路由器节点可显著提高跨小区流量的网络容量,但是小区内流量的网络容量增长速度明显高于跨小区流量的网络容量增长速度。

As the key measurement indices for network performance ,network capacity is a focus of Mesh research .Based on the analysis of architecture of hybrid mesh network ,the traffic pattern has been divided into intra-cell traffic pattern and inter-cell traffic pattern .The network capacity of in-tra-cell traffic pattern and the network capacity of inter-cell traffic pattern are both studied .The net-work capacity of hybrid mesh network is the sum of intra-cell traffic pattern and inter-cell traffic pat-tern .The simulation results show that dividing user nodes into more cells can increase the network capacity of intra-cell traffic pattern ,and deploying more base stations can increase the network capaci-ty of inter-cell traffic pattern .The network capacity of intra-cell traffic pattern grows faster than the network capacity of inter-cell traffic pattern .
