Abstract :
In this paper we used a DiffServ network model for the wired network where the ingress executed enhanced token bucket three color marker system (ETBMS). The framework also describes a video differentiator present in the access point which identifies the video packets and maps it to corresponding IEEE 802.11e prioritized video service queue. Using simulations the proposed concept is examined with QoS parameters like end-to-end delay, video quality and MSE. The results illustrate that the proposed scheme exhibits better video delivery and QoS in heterogeneous networks
