Multimedia streaming applications have stringent Quality-of-Service (QoS) requirements. Typically, each packet is associated with a packet delivery deadline. This work models and considers streaming broadcast of stored video over the downlink of a single cell. We first generalize the existing class of immediately-decodable network coding (IDNC) schemes to take into account the deadline constraints...
In this paper we study the feasibility of utilizing wireless local area network (WLAN) technology to deliver the triple-play services (video, voice and data) over a specific system model. Existing protocols are shown to not efficiently manage the wireless channel therefore we propose a new triple-play time division multiple access (TP-TDMA) media access control (MAC) protocol to provide Quality of...
The explosive demands of multimedia services have been grown up to support delay-sensitive applications, e.g., VoIP and streaming using codec. When a mobile node (MN) moves across different types of networks, the codec should be effectively adapted according to the significant change of network condition, i.e., throughput and delay. Therefore, in this paper, we propose a codec adaptation for vertical...
How good is a best effort network for different services in multi-service LTE networks? In this paper, we try to answer the question in the context of capacity of an LTE network with users concurrently running multiple services. We present a system simulation study for two-service scenarios with VoIP and a second service represented by real-time video, mobile TV, or web surfing. We present results...
