In this paper a crossed application and physical layer retransmission scheme is proposed for video streaming services in hybrid wireline and wireless networks. Each video packet carries the importance levels of succeeding packets at the application layer. In wireless transmission, by mapping the packet importance levels to different number of physical layer HARQ retransmissions, data packets are differentially...
Recent technological advances in code division multiple access (CDMA) with multiuser detection (MUD) allow to consider this technology for future wireless Ad Hoc networks. Due to the fundamentally different physical layer architecture, application of MUD in Ad Hoc networks requires novel approaches for medium access control (MAC) and scheduling mechanisms in order to take advantage of the new features...
