Optimal strategies in MAC protocols
2004 IEEE International Conference on Communications (IEEE Cat. No.04CH37577), 2004We have analyzed the distributed MAC protocols by using game theoretic concepts. Specifically, we have modelled the "access" game as a non-cooperative game with incomplete information. We have proven the existence of optimal strategies for individual users. We have derived approximate formulae for optimal transmission probabilities in two cases: single

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.

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 ...

A MAC protocol for multihomed WLANs
2008 IEEE International Symposium on Wireless Communication Systems, 2008In many cases, a mobile user has the option of connecting to one of several 802.11 access point (APs). We consider the case when users multihome, i.e., split their traffic among all available APs, based on the long-term channel characteristics such as burstiness and packet error rate.

VC-MAC: A Cooperative MAC Protocol in Vehicular Networks
IEEE Transactions on Vehicular Technology, 2009Vehicular networks are experiencing rapid growth and evolution under the increasing demand of vehicular traffic management and ubiquitous network connectivity. In particular, the amount of information to be downloaded from the roadside-deployed gateways is dramatically increasing.

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 ...

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,

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

AS-MAC: An asynchronous scheduled MAC protocol for wireless sensor networks
2008 5th IEEE International Conference on Mobile Ad Hoc and Sensor Systems, 2008Energy efficiency of the MAC protocol is a key design factor for wireless sensor networks (WSNs). Due to the importance of the problem, a number of energy efficient MAC protocols have been developed for WSNs. Preamble-sampling based MAC protocols (e.g., B-MAC and X-MAC) have overheads due to their preambles, and are inefficient at large wakeup ...
