Context-Aware Cross Layered Multimedia Streaming Based on Variable Packet Size Transmission (original) (raw)

Abstract

Multimedia streaming is usually disturbed by the surroundings. Especially in the ubiquitous computing environment, seamless multimedia service is difficult to provide due to harsh environment of wireless network and limited power of small mobile devices. In this paper we propose a scheme which can enhance the QoS of MPEG-4 streaming. By exhaustive experimental test, we find that the QoS of multimedia streaming significantly depends on the SNR (Signal-to-Noise Ratio). The proposed scheme employs five different packet sizes and selects a one according to the SNR value and the data on the packet delay and loss. Experiment on MPEG-4 video transmission reveals that the proposed streaming with variable packet size allows fast adaptation before the error propagates, minimizes the power consumption, and saves the buffer space compared to the streaming with fixed packet size.

This research was supported by the Ubiquitous Autonomic Computing and Network Project, 21st Century Frontier R&D Program in Korea and the Brain Korea 21 Project in 2005.
