In this work, we propose using video caching in the wireless relay networks (WRNs) for video on demand (VoD) service. We assume the relay station (RS) of the WRNs is capable of caching a small portion of the ongoing video stream. The cached video data can be used to accommodate new user requests. Previous works on video caching for VoD are in the context of overlay network, where the physical topology...
In this work, we discuss how to support video-on-demand service in multi-hop WiMax mesh networks. We are interested in the scenario that end users connect to the video servers through the base station of the multi-hop WiMax networks. We propose a model that can jointly solve the admission control and channel scheduling problems. Our proposed approach guarantees the required data rate is achieved for...
