Media access control manner with QoS for control network

2008 27th Chinese Control Conference, 2008
Control network takes responsibility for data communication in the networked control system (NCS), so the media access control of network is the key to guaranteeing the efficiency of the system. The paper presents a novel variable priority token passing data communication manner for the media access control in control network. The theoretical analysis,

Co-operative channel Media Access Control Mechanism

2014 International Conference on Computer Communication and Informatics, 2014
Media Access Control Mechanism is use to control multiple channel access by multiple users. To remove the drawbacks of MAC, Dual-MAC protocol has been devised in which dual channels are used one for control packets and other for the transmission of data packets.

Plane cover multiple access: a media access control strategy for wireless environments

ICUPC '98. IEEE 1998 International Conference on Universal Personal Communications. Conference Proceedings (Cat. No.98TH8384), 2002
In order to support future demand for mobile, wireless data communications, a packet based transmission scheme needs to be adopted. Such a paradigm could support data as well as voice and multimedia transmissions and would use the scarce wireless spectrum in a more efficient way than the conventional circuit switched model.

Media Access Control Protocols Review for UWB Networks

2006 First International Symposium on Pervasive Computing and Applications, 2006
Pervasive computing environments require ubiquitous interfaces for customers. The emerging wireless technology-Ultra Wide Band (UWB) is expected to be a promising candidate in these environments thanks to the efficiency of impulse radio (IR). Former MAC protocols for narrow band became unfit for the novel UWB PHY and numbers of protocols emerge.

Layered Access Control Schemes on Watermarked Scalable Media

2005 IEEE International Symposium on Circuits and Systems, 2005
Intellectual property (IP) protection is a critical element in multimedia transmission and delivery systems. Conventional IP protection can be categorized into encryption and watermarking. In this paper, a structure to perform layered access control of scalable media by combining encryption and robust watermarking is proposed and implemented. By taking

Research on A New Media Access Control Protocol

2020 Chinese Control And Decision Conference (CCDC), 2020
A new MAC protocol has been proposed for cognitive radio networks in the paper. This protocol guarantees the QoS of network for such applications by giving priority to applications with higher time delay requirements in the stage of channel reservation. The problems of low spectrum utilization and hidden terminals in cognitive radio networks are solved.

Arterial Performance Measures with Media Access Control Readers

Transportation Research Record: Journal of the Transportation Research Board, 2010
This study reports on the use of media access control (MAC) readers through the Bluetooth protocol by means of off-the-shelf equipment to measure arterial travel performance (segment travel time, average running speed, and origin–destination). First, the MAC reader technology was deployed at the same time that travel time runs by the traditional ...
