| Summary: | 碩士 === 國立清華大學 === 資訊工程學系 === 99 === In most localization system under 802.11, users need to install additional software in their wireless devices or use specific devices. But under the localization system architecture in this thesis, users connect the web site of localization system as long as use their wireless devices to locating.
There are several snoopers in the environment to scan all wireless channels and collect the wireless localization packets. The location server compares the signal of collected packets with the RSSI at specific areas and find the nearest site.
We propose a centralized adaptive polling algorithm for IEEE 802.11 localization systems to scan multiple wireless channels to improve polling algorithm and make all users fair.
