Improving Ieee 802.11 Wlan Handoff Latency by Access Point-Based Modification

IEEE 802.11 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 mobility service for users come with cost of handoff process required when mobile stations get connected from 1 Access point (AP) to another for continuous service. In existing 802.11 IEEE handoff procedure, the scanning phase can exceed duration of 200ms and packet loss can exceed 10%. Thus, proposed methodology focuses on achieving reduced overall handoff latency by implementing handoff delay duration less than 150ms which is the need for seamless service in IEEE 802.11 WLAN

Hybrid Hand-off Scheme for Performance Improvisation of Wireless Networks

Wireless systems administration is turning into an inexorably significant and well known method of giving worldwide data access to clients progressing. Handoff, the procedure where portable hubs select best passageway accessible to move information and its postpones make a major issue. A great deal of research has been done in most recent years to diminish the handoff delays happen in the various degrees of  WLAN correspondence. Because of the versatility of handoff, significant viewpoint in WLAN and cell correspondences are substantially more significant. Because of constrained scope of APs, WLAN likewise gives adequate data transmission to continuous spilling administrations. In this research article, various handoff plans are proposed to diminish the hand-off idleness and bolster quick hand-off in IEEE 802.11arcchitecture of wireless networks. In this article, we survey these quick handoff plots subjectively. In this work it is to make accessible preparation for prospect research on lessening the handoff inertness and give accentuation on necessity of quick handover for consistent network
