We propose a game-theoretic framework for quality-of-service (QoS) aware resource competition among coexisting wireless links in mobile wireless networks. The senders of wireless links use the constant transmit power and then the wireless resources of interest is characterized by time-slot length. Multiple wireless links will use the limited wireless resources through a time-slot competition game...
To save the precious wireless resources in wireless networks, we investigate cross-layer optimization schemes to reduce wireless resource consumption (WRC) for reliable mobile multicast. We characterize WRC by signal-to-noise ratio (SNR) per information bit and by power-delay product for scenarios without and with delay quality of service (QoS) constraints, respectively. Aiming at decreasing WRC,...
We propose an adaptive hybrid ARQ-FEC erasure-correcting scheme for QoS-driven mobile multicast services over wireless networks. The main features of our proposed scheme include: the low-complexity and dynamic adaptation to the variations of packet-loss levels and QoS-requirements. The low complexity is achieved by using the graph-code with linear time-complexity. To support diverse QoS-requirements...
