CRMA MAC protocol: A simulative analysis
Computer Communications, 1993This paper reports on an extended simulation analysis of the Cyclic Reservation Multiple Access (CRMA) Media Access Control (MAC) protocol. The analysis is divided into two parts. In the first part we study CRMA in underload conditions, i.e. when the offered load is lower than the medium capacity. In the second part we study CRMA in overload conditions,

Performance Evaluation of MAC Protocols
1996When a new system is designed, different alternatives offering the same functionality have to be compared with respect to performance, reliability, modularity, robustness, hardware and software complexity, development costs etc. In particular when no implementations are available, modelling is often the only way of evaluating and comparing the ...

MAC Protocol Engine for Sensor Networks
GLOBECOM 2009 - 2009 IEEE Global Telecommunications Conference, 2009We present a novel approach for Medium Access Control (MAC) protocol design based on protocol engine. Current way of designing MAC protocols for a specific application is based on two steps: First the application specifications (such as network topology and packet generation rate), the requirements for energy consumption, delay and reliability, and the

MAC-ASA: A New MAC Protocol for WMNs
2007 16th International Conference on Computer Communications and Networks, 2007This paper presents a novel medium access control (MAC) protocol intended to provide multi-hop wireless mesh networks with a higher throughput. The proposed MAC-ASA (medium access control with anticipated scheduling and agreement) protocol uses a modified version of the 802.11 CSMA/CA contention handling procedure integrated with a dynamic (time ...

Computer Networks and ISDN Systems, 1994
Abstract In this paper we describe the S++ protocol, a new protocol designed for Gbit/s LANs. The S++ protocol has evolved from our experience with an earlier protocol, called S, which was implemented as part of a Gbit/s LAN project. Our experience with S enabled us to identify ways by which the performance could be significantly improved while ...

H-Mac: A Hybrid MAC Protocol for VANET
2013This paper proposes a Hybrid Mac protocol(H-MAC) that combines reservation and competition mechanisms to solve the sudden burst data flow at link layer of the VANET(Vehicle Ad hoc Network). Based on the entire network time synchronization, H-MAC protocol divides a frame cycle into two parts.

RS-MAC: A fusion ranging of WSN MAC protocol
2013 IEEE 4th International Conference on Software Engineering and Service Science, 2013Focusing on ranging overhead for WSN, this paper researches the method of time-based ranging process into MAC protocol packet interaction, and analyzes ranging error and the method of error elimination, and proposes a fusion ranging of WSN RS-MAC protocol. The protocol can realize time-based ranging in the process of packet transmission.

Distributed Reservation-Based MAC Protocol for UWB WiMedia MAC
2012 IEEE 26th International Conference on Advanced Information Networking and Applications, 2012UWB WiMedia MAC has been widely used in wireless multimedia networks, but it suffers from inefficient channel utilization. In this paper, we propose a reservation based MAC protocol for multimedia data to increase the channel utilization efficiency. The proposed scheme has two components.
