In this paper, we address the problem of collaborative video caching in mobile ad-hoc networks. We consider network portraying static video server with wired interface to gateway node that is equipped with wireless interfaces, other nodes are requiring access to the video streams that is stored at video server. In order to reduce the average access latency as well as enhance the video accessibility,...
The third generation network which is vigorous nowadays will be followed by an all-IP infrastructure referred to as Next Generation Networks (NGN) in the near future. More specifically, the IP Multimedia Subsystem (IMS) is the only standardized way to offer IP based services that are enabled by one common core and all types of access networks and devices. The heterogeneity and mobility of the IMS...
