Random Access MAC for Efficient Broadcast Support in Ad Hoc Networks
"... Abstract- Wireless communications are becoming an important part of our everyday lifestyle. One major area that will have an enormous impact on the performance of wireless ad hoc networks is the medium access control (MAC) layer. Current random access MAC protocols for ad hoc networks support reliab ..."

1Analysis of random-access MAC schemes
, 2004
"... (title change; dropped “stable ” in (27) and added sentences in red) 1. Slotted Aloha [4] First-order analysis: if we assume there are infinite number of nodes, the number of new arriv-als in a slot is a Poisson r.v. with parameter. If retransmissions arrive in a highly random fash-ion, then the tot ..."

CHAIN: Introducing minimum controlled coordination into random access MAC
- In Proceedings of INFOCOM 2011
, 2011
"... Abstract-IEEE 802.11 DCF is the dominant protocol used in existing WLANs. However, the efficiency of DCF progressively degrades with the increase of contending clients in the network as well as the wireless link rate. To address this issue, in this paper, we present a distributed random media acces ..."

Enhancing the Performance of Random Access MAC Protocols for Low-cost SDRs
"... ABSTRACT Software Defined Radio (SDR) is a technology which facilitates experimentation and the practical realization of novel wireless communication systems. Especially low-cost SDRs, however, experience high communication delays due to the connection between the radio hardware and the host comput ..."

In Carrier Sense Multiple Access (CSMA) based protocols, especially the Clear Channel Assessment (CCA) as well as the subsequent channel access phase are subject to strict temporal constraints. In this paper, we
Adaptive Network Resource Management in IEEE 802.11 Wireless Random Access MAC
"... Abstract — Effective and efficient management of wireless network resources is attracting more and more research attention, due to the rapid growing deployment of wireless mesh and ad hoc networks and to the increasing demand for Quality of Service (QoS) support in these networks. This paper propose ..."

proposes an adaptive network resource management scheme in the popular IEEE 802.11 random access MAC by adaptively adjusting the minimum contention window sizes of traffic flows. First, a novel Generalized Processor Sharing (GPS) model is presented for the IEEE 802.11 random access MAC revealing
Joint Congestion Control and Random Access MAC in Multi-hop Wireless Networks via a Simplified Model
"... Abstract — In multi-hop wireless networks, maximizing network utility by joint congestion control and scheduling has drawn much research interest, and significant progress has been made that has yielded much insight. However, in attempting to maximize network utilization, most scheduling mechanisms ..."

We subsequently analyze its theoretical performance, and prove that the algorithm guarantees stability, and asymptotically converges to the near-optimal operational point. Future work is needed to investigate the mechanism by which such a scheme can be implemented. I.
