摘要：

提出了一种基于选播的无线Mesh 网络网关选取模型和相应的网关选取路由算法。该模型将所有网关节点抽象成一个选播组，将所有的网关节点组成一个网关树，实现对网关组成员的管理与维护。网关选取路由算法以时延为度量，通过有效的选播机制自适应地查找“最优”网关节点为客户节点服务，以提供响应最快的高质量的因特网接入服务。实验结果表明，该算法能在合理的时间内有效地解决多网关选取问题。

Abstract:

A gateway selection model based on anycast communication is presented, and an anycast-based gateway routing algorithm in wireless mesh network are designed. In this model, all the gateway nodes areabstracted as an anycast group and the member management and maintenance of gateway group are implemented by a gateway tree which is consisted of all gateway nodes. To provide the client node for the fastest response to Internet access, the gateway selection routing algorithm takes delay as a standard and adaptively select the best gateway node for its services through effective anycast mechanism. The experimental results show that this algorithm can effectively solve the gateway selection problem.

Key words: wireless mesh network, gateway selection, anycast, routing, delay
