Multi-layered video broadcasting over 1xEV-DO using multiple objective optimization

Abstract

In cellular environments video broadcasting is a challenging problem in which the number of users receiving the service and the average QoS has to be intelligently optimized. For video broadcasting in a 1xEV-DO system, the orthogonal Walsh codes may be distributed among the multiple layers of the scalable coded video stream. In this paper, we propose a novel, multiple objective optimized, multi-layered video broadcasting scheme for the 1xEV-DO system. With this scheme, the average observed service quality is maximized while minimizing the total number of time slots in which individual mobile subscribers experience outages. Simulations done for the ITU Pedestrian A and Vehicular B channels show that our proposed scenario provide significant increase to the average service quality while maintaining the total number of slots receiving no service as small as in original scenario.
