Improving video-on-demand performance by multi-channel/multicast approach in cellular networks

摘要

On-demand-video streaming has been applied in wired networks with success. However, it remains a challenging task in wireless networks due to bandwidth problems and the effect of wireless interference and client mobility. To address these problems, we unified cache server with multi-channel/multicast technique and improves speed up by limiting the number of video request from the remote server. The proposed solution is an efficient when more clients request the same video at the same or closer time. Also, video locality based on cache server, which located in the base station controller reduce core network traffics by elimination number of request to remote media services. The simulation results show that the suggested methods improve response time and speedup that lead to better quality of service.
