While decentralized medium access control (MAC) protocols are more popular in wireless networks, cluster based sensor networks are particularly amenable to centralized, polling based protocols. This paper presents an analytic model to evaluate the performance of a polling based MAC protocol in terms of the packet delay, buffer overflow rates and energy consumption. We show that the polling base...

Medium Access Control(MAC) protocol is quite important to the performance of underwater sensor networks(UWSNs). Recently, much research work has been done on the design of new MAC protocols for UWSNs to improve throughput and energy efficiency [1]–[3]. All these work is for the singlechannel network scenario. However, the fast development of underwater acoustic communication technologies enable...

This paper describes and analyzes a novel MAC protocol named distributed-control polling (DCP), which has been designed to bring together the most interesting features of distributed-control MAC protocols (e.g., DQDB) and centralized token-passing MAC protocols (e.g. , FASNET, FDDI, EXPRESS-NET). From the fully distributed MAC protocols, DCP acquires the capability to guarantee both a complete ...

This paper gives a short overview of the state of the art of time-division multiple access (TDMA) based medium access control (MAC) protocols for wireless sensor networks (WSN). These sensor networks have special requirements on MAC protocols, which make it impossible to function efficiently with the help of ordinary wireless MAC protocols. Research challenges and state of the art are described...

Media access control (MAC) protocols for mobile ad-hoc networks are of interest in applications ranging from wireless local area networks (WLANs) to global skywave highfrequency radio networks. Much of the recent work in wireless MAC protocols has emphasized networks with short turnaround times (e.g., IEEE 802.11 WLANs). However, some wireless networks suffer lengthy turnaround times in the phy...

This paper first discusses the machine to machine (M2M) domain architecture which becomes the basic model for hybrid Medium Access Control (MAC) protocols for large M2M networks and also it sets the background for hybrid MAC scheme. A review of the contention based and reservation based MAC protocols used in M2M networks is then made. Refer ences Liu,Y. , Yuen, C. , Chen, J. and Cao, X. 2013. A...

This paper reviews medium access control (MAC), an enabling technology in wireless sensor networks. MAC protocols control how sensors access a shared radio channel to communicate with neighbors. Battery-powered wireless sensor networks with many nearby nodes challenge traditional MAC design. This paper discusses design trade-offs with an emphasis on energy efficiency. It classifies existing MAC...

This article presents a survey on medium access control protocols for wireless multimedia networks. A basic overview of MAC protocol concepts is presented, and a framework is developed for comparisons.

Media Access Control (MAC) layer protocols have a critical role in making a typical Wireless Sensor Network (WSN) more reliable and efficient. Choice of MAC layer protocol and other factors including number of nodes, mobility, traffic rate and playground size dictates the performance of a particular WSN. In this paper, the performance of an experimental WSN is evaluated using different MAC laye...

Wireless sensor networks have recently gained a lot of attention from the researches. Wireless sensor networks are often partitioned into clusters, each managed by a cluster head (gateway). This paper reviews medium access control (MAC), an enabling technology in wireless sensor networks. MAC protocols control how sensors access a shared radio channel to communicate with neighbors in small area...
