QoE-Based Reduction of Handover Delay for Multimedia Application in IEEE 802.11 Networks

PROJECT TITLE :

QoE-Based Reduction of Handover Delay for Multimedia Application in IEEE 802.11 Networks

ABSTRACT:

Wireless local space network (WLAN) is turning into increasingly necessary because of the explosive growth of mobile knowledge traffic. The user in some hot spot areas is usually coated with multiple access points (APs). But, the next challenge is that the users' devices want to handover between these APs as the user moves, and it introduces large latency during the handoff process. For multimedia application, quality of expertise (QoE) is an essential measurement for network evaluation. However the large handover latency which provides rise to an interruption will greatly degrade the users' QoE to an intolerable extent. Therefore a neighbor list based proactive handoff scheme which has sufficient low handover latency will cut back service disruptions. The proposed theme exploits the active scan primarily based on information of neighboring APs, received signal strength indicator (RSSI), and variable bitrate video coding (VBR) to reduce handover delay and service interruption. Based on the analysis and simulation, it will be seen that the proposed theme will decrease the handover time efficiently and increase QoE.
