Overview

Evaluates MI-MAC, a reservation access protocol, when H.264 video shares a noisy cellular channel with voice and web traffic under heavy handoff load.

Key contributions

• One of the first studies to integrate H.264 streams with other multimedia traffic over wireless.
• Channel throughput above 60% (up to 71%) while meeting each traffic type's QoS.
• About 25% more voice capacity on average than a well-known competing protocol.

Abstract

We have recently introduced in the literature MI-MAC (Multimedia Integration Multiple Access Control), a new access control protocol for next generation wireless cellular networks which showed superior performance in comparison to other (TDMA and WCDMA-based) protocols when integrating various types of multimedia traffic. In this work, which to the best of our knowledge is one of the first in the literature to study the integration of H.264 streams with other types of multimedia traffic, we continue our work on MI-MAC. We evaluate the protocol’s ability to efficiently integrate streams from latest technology video encoders with other types of packet traffic over noisy wireless networks, especially in the case of significant handoff loads. We also discuss the differences between accommodating video traffic from previous technology encoders and H.264.
