The mobile cellular systems are expected to support multiple services with guaranteed Quality of Service(QoS). But, the ability of wireless systems to accommodate expected growth of traffic load and broadband services is limited by available radio frequency spectrum. Call Admission Control (CAC) is one of the resource management functions, which regulates network access to ensure QoS provisioning...
Spatial and temporal variations in network bandwidth constraints constitute serious challenges to the multicast distribution of real-time video content. We present a video multicast algorithm that combines multi-layered video encoding with feedback-based source adaptation in order to address varying bandwidth constraints in a multicast tree. The proposed algorithm uses a novel multicast flow control...
