Extension of handoff with the help of wider channels

Abstract

In this paper, we have discussed the issue of the IEEE 802.11 Wireless Local Area Networks (WLAN) based wireless blocking probability with its algorithm and upgrading of the channels. WLAN provides multimedia services like live telecast, video streaming, video conferencing, Voice over IP (VoIP) to its users. For deployment of these fast real time services, it needs stringent Quality of service (QoS) requirement such as delay time less than 150ms for VoIP, and packet loss rate of 1% . The user mobility service provides the handoff cost required when mobile stations are linked for continuous service from one access point ( AP). In existing 802.11 IEEE handoff procedure, the scanning phase can exceed duration of 200ms and packet loss can exceed 10%.  Through the implementation of handoff time of less than 150ms the proposed approach focuses on achieving reduced general handoff latency, which in IEEE 802.11 is sufficient for seamless operation.
