无线Mesh网络可扩展性相关技术

Scalability Techniques for Wireless Mesh Networks

无线移动通信中传输的数据密度持续增长对无线Mesh网络的系统性能提出了挑战。在无线自组织网络中,由于存在随着节点数目的增加而平均节点容量逐步降低的规律,因此无线Mesh网络的大规模组网难以实施。无线Mesh网络可扩展性对于增强无线Mesh网络的自适应组网能力至关重要,因此,文章对在Mesh基站和Mesh移动台上采用的与可扩展性相关的关键技术,如信道分配技术、智能路由技术、多天线技术、节点分类和QoS分级技术、协作传输技术等,进行了探讨。

With the rapid development of wireless mobile communications, the incremental data density challenges the system performance of wireless Mesh networks. For Ad hoc network, the average capacity decreases as the number of the nodes increases. Therefore, there exists a bottleneck in deploying large scale wireless Mesh networks. The scalability techniques are crucial for the adaptive networking of wireless Mesh networks. Key scalability techniques for wireless Mesh networks are studied, and the main techniques for the Mesh base station and Mesh mobile client, such as channel allocation, intelligent routing, multi-aerial, node classifying, QoS level and cooperative transmission are introduced.
