| 摘 要： | 无线网状网是一种新兴的宽带无线网络接入技术,支持不同应用场景的无线接入。IEEE802.11s标准定义了一种默认的路由选择算法,称为混合无线网状网协议(HWMP)。HWMP将把树状路由为基础的先应路由模式和按需路由模式相结合。对先应路由模式进行改进,以减小网络开销,增强网络性能。从仿真结果可以看出,改进后的算法在数据包到达率、平均端到端时延和吞吐量指标上达到了更佳的性能。

| Abstract: | Wireless Mesh Network (WMN) is an emerging broadband wireless access technology to support different application scenarios of wireless access. IEEE 802.11s standard defines a default routing algorithm, called Hybrid Wireless Mesh Protocol (HWMP). HWMP combine tree-based proactive routing mode with on-demand routing mode. In this paper, the proactive routing mode to reduce network overhead and enhance network performance is improved. It can be seen from the simulation results that the improved algorithm reac... |
