Fast neighbor positioning and medium access in wireless networks with directional antennas
(2013)We study the problem of fast neighbor positioning and medium access in wireless networks with directional antennas. In this problem, the cross-layer dimension inherently comes into stage through the impact of PHY-layer ... -
Medium access games: The impact of energy constraints
(2011)We consider random medium access schemes for devices that support sleep modes, i.e. turning off electronic compartments for energy saving. Due to hardware limitations, sleep mode transitions cannot occur at the medium ... -
Queue and channel state awareness for maximum throughput access control in CSMA/CA-based wireless LANs
(2009)This paper introduces two important enhancements to the IEEE 802.11 medium access control (MAC) protocols which are not considered in the current IEEE 802.11 MAC protocol: the channel state between the transmitter and the ...
