FMAC/CSR: a Fair MAC Protocol for Wireless Ad-hoc Networks
Recently, the issue of achieving MAC layer fairness in wireless ad-hoc networks has been extensively addressed. Most of the published schemes are sender-based, meaning that a sender (of a flow) contends for the shared medium based on its own understanding of the contention on the medium. However, as clearly shown in this paper, in a wireless ad-hoc network, a sender may not have precise informa...
متن کاملA Cross-layer Contention Based Synchronous MAC Protocol for Transmission Delay Reduction in Multi-Hop WSNs
Recently designed cross-layer contention based synchronous MAC protocols like the PRMAC protocol, for wireless sensor networks (WSNs) enable a node to schedule multi-hop transmission of multiple data packets in a cycle. However, these systems accommodate both the request-to-send data process and the confirmation-to-send data process in the same data transmission scheduling window (i.e. data win...
متن کاملUser Fairness Scheme with Proportional Fair Scheduling in Multi-user MIMO Limited Feedback System
In Multi-user MIMO (MU-MIMO) downlink system, suitable user selection schemes can improve spatial diversity gain. In most of previous studies, it is always assumed that the base station (BS) knows full channel state information (CSI) of each user, which does not consider the reality. However, there are only limited feedback bits in real system. Besides, user fairness is often ignored in most of...
متن کاملAchieving Proportional Fairness using Local Information in Multi-hop Aloha Networks
We address the problem of fair medium access control in multi-hop Aloha networks, with the objective of achieving proportionally fair rates. We consider a general multi-hop wireless network, and show how the attempt probabilities/attempt rates in Aloha protocols should be set so that the achieved rates are globally proportionally fair. For both slotted and unslotted Aloha, we argue that it is p...
متن کاملAchieving MAC Fairness in Wireless Ad-hoc Networks by Cooperation between Sender and Receiver
Achieving MAC layer fairness in wireless ad hoc networks is a very challenging issue. In this paper, we first show that IEEE 802.11 exhibits substantial unfairness due to the concealed information problem (explained in this paper later), imprecise collision detection mechanism, and high contention. To achieve MAC fairness, we introduce a Fair MAC protocol using Cooperation between Sender and Re...
