Abstract

The need for QoS for multimedia traffic arouse from the fact that the current network is a best effort network where all packets are treated equally irrespective of their importance. Moreover when a video packet changes its mode of transport from wired to wireless there arises a need to identify these packets and provide them with prioritized service to achieve end-to-end QoS. In this paper we used a DiffServ network model for the wired network where the INGRESS executed Enhanced Token Bucket Three 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. We demonstrated via simulation the proposed concept and examined the QoS parameters like end-to-end delay and Video Quality. The results illustrate that the proposed scheme exhibits better video delivery and QoS in heterogeneous networks.
