摘要:

在固定无线城域网基础上支持其移动性的IEEE802.16e[1]是一种有效的移动宽带无线接入解决方案,将HMIPv6[2]与IEEE802.16e有机结合,可以使切换的时延和丢包率都明显减小。IEEE802.16同时支持Mesh模式,可以获得更大的网络覆盖范围以及降低设备成本。本文从理论上分析了在无线 Mesh 网络中采用传统位置管理策略的网络开销,并与典型的采用HMIPv6的WiMAX网络进行了对比。分析结果表明,WiMAX Mesh网络需要结合拓扑特性考虑更加有效的位置管理策略,以更好地支持移动性及多种业务的应用。

Abstract:

Supporting the mobility of the IEEE802.16e[1] standard on fixed WirelessMANs is supposed to be a promising solution for mobile broadband wireless access (BWA). By integrating HMIPv6[2] with the IEEE802.16e system,the performance of the system can be enhanced greatly. The mesh topology in the IEEE802.16 standard can achieve wide market coverage as well as low investments of the facility. In this paper, the cost and delay of the traditional location management schemes in Wireless Mesh Networks are analyzed theoretically and compared with that of the typical cellular networks. The results show that a more effective location management scheme which is suitable for the WiMAX Mesh topology should be proposed so that it can better support the mobility and application of different services.

Key words: WiMAX;HMIPv6;Mesh;location management
