The extension of the ATM (Asyncronous Transfer Mode) protocol stack to the wireless segment requires the introduction of a MAC (Medium Access Control) layer able to provide reliable connection services to the network layer. Two basic functions of the MAC layer are resource allocation and error control. In this paper we analyze these issues and consider a MAC scheme for TDMA systems based on ARQ...

This paper introduces Human Energy Harvesting Medium Access Control (MAC) protocol (HEHBMAC), a hybrid polling MAC suitable for Wireless Body Area Networks (WBANs) powered by human energy harvesting. The proposed protocol combines two different medium access methods, namely polling (IDpolling) and probabilistic contention (PC) access, to adapt its operation to the different energy and state (ac...

Multiple input multiple output (MIMO) and orthogonal frequency division multiplexing (OFDM) are very promising techniques to exploit diversity in the physical layer of broadband wireless communications. However, the application of these techniques to broadband multihop ad hoc networks is subject to inefficiencies since existing medium access control (MAC) schemes are designed to allow only one ...

In this paper we present an analysis of a MAC (Medium Access Control) protocol for wireless sensor networks. The purpose of this protocol is to manage wireless media access by constructing a Time Division Media Access (TDMA) schedule. APMC (Approximate Probabilistic Model Checker) is a tool that uses approximation-based verification techniques in order to analyse the behavior of complex probabi...

Fair allocation of bandwidth and maximization of channel utilization are two important issues when designing a contention-based wireless medium access control (MAC) protocol. However, achieving both design goals at the same time is very difficult, and has not yet been addressed elsewhere. In this paper, we study this challenging problem, particularly for data communications in IEEE 802.11 wirel...

Recently there has been a considerable research interest in the next generation mobile networks. The new networks promises to be able to handle multi-service (voice, data, video) traffic. For fixed networks ATM is considered as the enabling technology for this traffic, so to ease the transition, as well as aid simple interworking, it is natural to use ATM for the mobile network as well. To supp...

In this study we investigate the performance of TCP and MAC layer in a wireless multi-hop network. Using simulation, we provide new insights into the interactions between TCP and various MAC layer protocols, including CSMA, FAMA and 802.11. These MAC protocols were chosen because they provide an evolution of wireless medium access schemes, starting with carrier sensing (CSMA), then evolving to ...

Medium access control (MAC) protocols coordinate channel access between wireless stations, and they significantly affect the network throughput of wireless ad-hoc networks. MAC protocols that are based on a multichannel model can increase the throughput by enabling more simultaneous transmission pairs in the network. In this paper, we comprehensively compare different design methods for multich...

In this chapter, the practical and experimental aspects of medium access control protocol design for wireless sensor networks are discussed. We outline the basic design principles of medium access control procedures and the general development trends from the perspective of real world implementations. We take into account especially energy consumption and latency requirements. We share our expe...

Traditional wireless Medium Access Control (MAC) protocols suffer from a number of drawbacks when used in vehicle to roadside networks. This paper proposes an efficient MAC protocol that addresses a number of critical aspects required for MAC protocols for vehicle to roadside networks including elimination of hidden terminals, prioritized and fast handoff, fairness among nodes and optimal choic...
