摘要/Abstract

摘要： IEEE 802.16标准的Mesh拓扑结构能够获得更大的网络覆盖范围、降低运营商建网初期的投资。然而，现有标准没有规定如何在Mesh网络中实现位置管理。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开销和延时，并与典型蜂窝网络中的情况进行了对比。分析结果表明，传统的位置管理策略在WiMAX Mesh网络中的性能十分低效，需要结合Mesh网络的拓扑特性重新考虑位置管理策略。

Abstract: The meshed topology in IEEE 802.16 standard provides high reliability，effective market coverage，and scalability，as well as low upfront investments.However，the standard does not specify the location management mechanism.In this paper，the author analyzes theoretically the cost and delay of traditional location management schemes in wireless mesh networks and compares it with that of typical cellular networks.The result shows it is necessary to propose a new location management scheme which takes the character of wireless multi-hop in WiMAX Mesh networks into account.
