Energy-Delay Analysis of MAC Protocols in Wireless Networks
In this paper the tradeoff between energy and delay for wireless networks is studied. A network using a request-to-send (RTS) and clear-to-send (CTS) type medium access control (M...

Quasi-Optimal Channel Assignment for Real-Time Video in OFDM Wireless Systems
In this paper, real-time video transmission with quality of service (QoS) assurance over orthogonal frequency division multiplexing (OFDM) wireless systems is studied. Three quasi-...
