The tremendous capacity gains promised by space division multiple access (SDMA) depend critically on the accuracy of the transmit channel state information. In the broadcast chann...
This work describes a detailed simulation-based study of the performance of an IEEE 802.11e Medium Access Control (MAC) layer over an IEEE 802.11g Physical (PHY) layer. The study ...
In this study, we analyze the sleep-mode operation for power management of a mobile station in the IEEE802.16e Wireless Metropolitan Access Network. For the analysis we use the M/...
— We explore the advantages of intelligently dropping a small fraction of packets that arrive for transmission over a time varying wireless downlink. Without packet dropping, the...
This paper concerns the cross-layer design between physical layer and MAC (Multiple Access Control) layer in asynchronous wireless random access network. The proposed cross-layer d...
