Handoff Latency Minimization by using Access Point by GPS using Selective scanning. International Journal of Computer Applications. 45, 19 ( May 2012), 13-19. DOI=10.5120/7024-9660
Due to rapid growth in IEEE 802. 11 based Wireless Local Area Networks (WLAN), handoff has become a burning issue. A mobile node (MN) requires handoff when it travels out of the coverage area of its current access point (AP) and tries to associate with another AP. But handoff delays provide a serious barrier for such services to be made available to mobile platforms. Different works have been done to reduce the handoff delay. In this paper, we have also a proposed a method to reduce handoff latency for IEEE 802. 11 wireless networks with map based on GPS. IEEE 802. 11 uses 11 possible channels of 14 of which only the channels 1, 6 and 11 do not mutually overlap. Using these channels and 8 others by selective scanning here we have reduced the handoff off delay and later the authentication as well as re-association delay.
