ABSTRACT
Now a day, IEEE 802.11 based wireless local area networks (WLAN) have been widely deployed for business and personal applications. The main issue regarding wireless network technology is handoff or hand over management. Quality of service (QoS) demanding applications like Voice over IP (VoIP) and multimedia require seamless handover. But handoff delay (time required to perform hand off) provides a serious barrier for such services to be made available to mobile platforms. Throughout the last few years so many researches had been done to reduce the hand off delay. Here we propose a new scanning method in which we determine the distance of nearest access points from the mobile node to bypass the main processes involved in increasing Medium Access Control (MAC) layer handoff latency.
