无线Mesh网基于簇的多信道分配策略

摘要

Nowadays, as a kind of multi-hop self-organizing network ,Wireless Mesh Networks(WMN) have been become the hot topic. As a kind of hierarchical structure , cluster structure is the most widely used in self-organizing . However,the formation and maintenance of a hierarchical structure depends on certain clustering algorithm.Based on the cluster ideal, with a multi-channel MAC technology can improve the goodput of the WMN . The comprehensive method in the Mesh network will present the multi-channel key technology and the cluster structure in the self-organizing network . So a multi-channel assignment strategy is proposed which is suited in the WMN. The results of Simulation show that this strategy has greater goodput than the classic method which is Hyacinth.%目前无线Mesh网作为一种多跳的自组网络在国内外十分活跃，而簇结构是自组网络中应用最为广泛的层次结构，这种层次的形成和维护依赖于某种算法。以簇作为切入点引入多信道MAC技术提出一种提高Mesh网吞吐量的方法，将目前在Mesh网中的多信道的关键技术与自组网中的簇结构相结合，提出一种适合Mesh网的基于簇的多信道分配方法。通过仿真，它与经典的Hyacinth相比较在吞吐量方面得到显著地提高。
