mu mimo mac protocols for wireless Local Area Networks a survey
IEEE Communications Surveys and Tutorials, 2016Co-Authors: Ruizhi Liao, Boris Bellalta, Miquel Oliver, Zhisheng NiuAbstract:As wireless devices boom and bandwidth-hungry applications (e.g., video and cloud uploading) get popular, today's wireless Local Area Networks (WLANs) become not only crowded but also stressed at throughput. Multiuser multiple-input–multiple-output (MU-MIMO), an advanced form of MIMO, has gained attention due to its huge potential in improving the performance of WLANs. This paper surveys random access-based medium access control (MAC) protocols for MU-MIMO-enabled WLANs. It first provides background information about the evolution and the fundamental MAC schemes of IEEE 802.11 Standards and Amendments, and then identifies the key requirements of designing MU-MIMO MAC protocols for WLANs. After this, the most representative MU-MIMO MAC proposals in the literature are overviewed by benchmarking their MAC procedures and examining the key components, such as the channel state information acquisition, decoding/precoding, and scheduling schemes. Classifications and discussions on important findings of the surveyed MAC protocols are provided, based on which, the research challenges for designing effective MU-MIMO MAC protocols, as well as the envisaged MAC's role in the future heterogeneous Networks, are highlighted.

COMSNETS (Extended Selected Papers) - A Directional Medium Access Control Protocol for 5G Millimeter-Wave Local Area Networks
Lecture Notes in Computer Science, 2018Co-Authors: Bharadwaj Satchidanandan, Simon Yau, Siva Santosh Ganji, Amal Ekbal, Ahsan Aziz, P R Kumar, Nikhil KundargiAbstract:The vast amount of spectrum available at millimeter-wave bands has made millimeter-wave communications one of the key enabling technologies of the fifth-generation cellular network. The high directionality of the transmitter and the receivers operating at millimeter-wave frequencies introduces certain novel challenges for medium access control. Specifically, in a scenario where there is relative motion between the transmitter and the receivers, the transmitter must keep track of the direction in which each received signal is, and the receivers must keep track of where the transmitter is, so that they can orient their antenna boresight towards each other, or in a non-line-of-sight environment, in directions that optimize the link gain, in order to establish a physical link. In this paper, we propose TrackMAC, a directional medium access control protocol for millimeter-wave Local Area Networks, that allows an access point to efficiently track every station associated with it at small overheads. The proposed protocol can be implemented squarely within the specifications of the IEEE 802.11ad standard for millimeter-wave Local Area networking.

trackmac an ieee 802 11ad compatible beam tracking based mac protocol for 5g millimeter wave Local Area Networks
Communication Systems and Networks, 2018Co-Authors: Bharadwaj Satchidanandan, Simon Yau, Amal Ekbal, Ahsan Aziz, P R Kumar, Nikhil KundargiAbstract:This paper presents a novel framework for MAC design for millimeter-wave (mm-wave) mobile wireless Networks. Specifically, we consider an infrastructure wireless network in which both the Access Point (AP) and the mobile stations (STAs) communicate in the 60GHz band. In order to overcome the high path loss that is characteristic of mm-wave frequencies, both the transmitter as well as the receivers employ beamforming and use highly directional beams for transmission and reception. In such a scenario, traditional Medium Access Control (MAC) protocols such as CSMA/CA, which rely on the omni-directional nature of transmissions, may no longer be viable for efficient medium access control. It is necessary for the AP to know the directions that the associated STAs are in so that it can steer its transmissions to an intended receiver in that receiver's direction. In light of this, we propose TrackMAC, a directional MAC protocol that (i) has the property that it continuously tracks the direction of every associated station which, in general, is mobile, and (ii) can be implemented squarely within the specifications of the IEEE 802.11ad standard for mm-wave Wireless Local Area Networks (WLAN). The efficacy of the proposed architecture is demonstrated using computer simulations.

next generation ieee 802 11 wireless Local Area Networks current status future directions and open challenges
Computer Communications, 2016Co-Authors: Boris Bellalta, Luciano Bononi, Raffaele Bruno, Andreas KasslerAbstract:A new generation of Wireless Local Area Networks (WLANs) will make its appearance in the market in the forthcoming years based on the amendments to the IEEE 802.11 standards that have recently been approved or are under development. Examples of the most expected ones are IEEE 802.11aa (Robust Audio Video Transport Streaming), IEEE 802.11ac (Very-high throughput at < 6 GHz), IEEE 802.11af (TV White Spaces) and IEEE 802.11ah (Machine-to-Machine communications) specifications. The aim of this survey is to provide a comprehensive overview of these novel technical features and the related open technical challenges that will drive the future WLAN evolution. In contrast to other IEEE 802.11 surveys, this is a use case oriented study. Specifically, we first describe the three key scenarios in which next-generation WLANs will have to operate. We then review the most relevant amendments for each of these use cases focusing on the additional functionalities and the new technologies they include, such as multi-user MIMO techniques, groupcast communications, dynamic channel bonding, spectrum databases and channel sensing, enhanced power saving mechanisms and efficient small data transmissions. We also discuss the related work to highlight the key issues that must still be addressed. Finally, we review emerging trends that can influence the design of future WLANs, with special focus on software-defined MACs and the internet-working with cellular systems.
