CSMA versus prioritized CSMA for air-traffic-control improvement [PDF]
Proceedings, IEEE Aerospace Conference, 2003 OPNET version 7.0 simulations are presented involving an important application of the aeronautical telecommunications network (ATN), controller pilot data link communications (CPDLC) over the VHF data link mode 2 (VDL-2). Communication is modeled for essentially all incoming and outgoing nonstop air-traffic for just three United States cities ...

Towards a System Theoretic Approach to Wireless Network Capacity in Finite Time and Space [PDF]
, 2013 In asymptotic regimes, both in time and space (network size), the derivation of network capacity results is grossly simplified by brushing aside queueing behavior in non-Jackson networks.

Multiband CSMA/CA with RTS-CTS strategy [PDF]
, 2014 We present in this paper a new medium access control (MAC) scheme devoted to orthogonal frequency division multiple access (OFDMA) systems which aims at reducing collision probabilities during the channel request period.

Exploiting Regional Differences: A Spatially Adaptive Random Access [PDF]
, 2015 In this paper, we discuss the potential for improvement of the simple random access scheme by utilizing local information such as the received signal-to-interference-plus-noise-ratio (SINR).

Performance of CSMA in Multi-Channel Wireless Networks
, 2011 We analyze the performance of CSMA in multi-channel wireless networks, accounting for the random nature of traffic. Specifically, we assess the ability of CSMA to fully utilize the radio resources and in turn to stabilize the network in a dynamic setting

Implementing utility-optimal CSMA [PDF]
2009 47th Annual Allerton Conference on Communication, Control, and Computing (Allerton), 2009 Hundreds of papers over the last two decades have studied the theory of distributed scheduling in wireless networks, including a number of them on stability or utility maximizing random access. Several publications in 2008 studied an adaptive CSMA that in theory can approach utility optimality without any message passing under a number of assumptions ...
