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.
