User activity dependent paging scheme in a multi-cell campus WLAN environment
Abstract
IEEE 802.11 Wireless Local Area Network (WLAN) is becoming the prevailing technology for the broad· band wireless Internet access. However, IEEE . 802.11 WLAN has been discovered to be naturally weak in supporting the mobility of mobile host (MH) when there is no traffic to be served for the MHs. Quite a number of commendable works have been done to introduce paging · in WLAN and,.thereby properly manage scarce network resources such as bandwidth and power. In this work, the authors consider.it pertinent to go a ·.step further and design a paging algorithm for campus WLAN, which will take advantage of the unique campus setting and activities We, therefore, · propose a User-Activity Dependent Paging Scheme (UADPS) in a Multi-Cell Campus WLAN Environment a paging algorithm that considers mobile devices in a multi cell WLAN. This is because we believe that such algorithm will not only be simple to implement, but will make a great positive impact on resource savings for on-campus WLAN users. Results obtained shows that the UADPS utilizes less. network resources in searching for an MH when compared to the IEEE 802 .. 11 power save mode algorithm.
