WiMap: Fast handover for 802.11 mobile devices

Abstract

Low latency handover is desired to support real time applications, such as VoIP. We introduce WiMap, a new handover scheme that uses past information of handovers. Through our analysis and simulation, we show that WiMap performs 50% faster than traditional handover solutions. WiMap does not require modifications to the access points or WLAN infrastructure and thus can be efficiently implemented.
