摘　　要：拓扑控制技术可以有效地提高无线Mesh网络的网络容量并增强网络可靠性,采用拓扑控制所构成的规则网络拓扑结构还具有良好网络路由和链路分集能力。通过对随机拓扑和规则拓扑的网络容量与拓扑特征的分析,表明规则拓扑在无线Mesh网络中具有优良网络品质。为了使规则拓扑适应密集组网的应用环境,设计一种虚拟层次化的规则拓扑结构;进一步通过拓扑分割构成微虚拟小区解决网络的可扩展性问题。仿真证明规则拓扑及其拓扑分割技术提高了无线Mesh网络容量等网络性能。Topology control technique constructs the wireless Mesh networks＇topology with high capacity and reliability.Regular topology has the advantages in routing and link diversity.By contrasting network capacity and topologic characteristic with the random topology,proved regular topology to have better performance in wireless Mesh networks.Presented a virtual hierarchical wireless Mesh network structure for density deployment of network nodes.Partitioned this network structure into micro-cells to enhance the network capacity.Simulation proves the increased network capacity by using regular topology,and micro-cells have further improved the network performance.
