An Energy-Efficient MAC Protocol for Wireless Sensor Networks

by Wei Ye, John Heidemann, Deborah Estrin , 2002
"... This paper proposes S-MAC, a medium-access control (MAC) protocol designed for wireless sensor networks. Wireless sensor networks use battery-operated computing and sensing devices. A network of these devices will collaborate for a common application such as environmental monitoring. We expect senso ..."

A Rate-Adaptive MAC Protocol for Multi-Hop Wireless Networks

by Gavin Holland, Nitin H. Vaidya, Paramvir Bahl , 2001
"... Wireless local area networks (W-LANs) have become increasingly popular due to the recent availability of affordable devices that are capable of communicating at high data rates. These high rates are possible, in part, through new modulation schemes that are optimized for the channel conditions bring ..."

relatively few proposals for W-LANs. In this paper we present a rate adaptive MAC protocol called the Receiver-Based AutoRate (RBAR) protocol. The novelty of RBAR is that its rate adaptation mechanism is in the receiver instead of in the sender. This is in contrast to existing schemes in devices like

An Adaptive Energy-Efficient MAC Protocol for Wireless Sensor Networks

by Tijs van Dam, Koen Langendoen - SENSYS'03 , 2003
"... In this paper we describe T-MAC, a contention-based Medium Access Control protocol for wireless sensor networks. Applications for these networks have some characteristics (low message rate, insensitivity to latency) that can be exploited to reduce energy consumption by introducing an active/sleep du ..."

Energy – Efficient MAC Protocol (EE-MAC Protocol)

by Garima Bhardwaj, Vasudha Vashishtha
"... Abstract- Because of the difficulty in recharging or replacing the batteries of each node in a Wireless Sensor Network, the energy efficiency of the system is a major issue in the area of network design. Other critical parameters such as delay, adaptability to traffic conditions, scalability, system ..."

, system fairness, and throughput and bandwidth utilization are mostly dealt as secondary objectives. Some sensor network applications adopt IEEE 802.11-like MAC protocol, which is however, not a good solution for sensor network applications because it suffers from energy inefficiency problem. The adaptive

An Enhanced VeMAC Protocol

by Vandung Nguyen, Oanh Thi, Kim Tran, Duc Ngoc, Minh Dang, Choong Seon Hong
"... VeMAC protocol is a medium access control protocol based on the direction of moving vehicle. VeMAC reduces the transmission collision and supports higher throughput on the control channel (CCH). However, the number of time slots in a frame is limited and affects the time slot reservation on the CCH. ..."

Sensor Networks: MAC Protocols

by Jukka Valkonen
"... Abstract. Sensor networks are autonomous networks that consist of up to thousands of nodes performing some specific task such as sensing environmental events. The devices are highly constrained: The devices have for example poor computing capabilities and battery resources. The nodes need to communi ..."

to communicate with other nodes to convey the sensed information to a device collecting the data. When designing MAC protocols for sensor networks, the constraints of sensor networks need to be taken into account. In this paper, short description of sensor networks is presented followed by descriptions of some

X-mac: A short preamble mac protocol for duty-cycled wireless sensor networks

by Michael Buettner, Gary V. Yee, Eric Anderson, Richard Han - in SenSys , 2006
"... In this paper we present X-MAC, a low power MAC protocol for wireless sensor networks (WSNs). Standard MAC protocols developed for duty-cycled WSNs such as B-MAC, which is the default MAC protocol for TinyOS, employ an extended preamble and preamble sampling. While this “low power listening ” approa ..."

Blind Cognitive MAC Protocols

by Omar Mehanna, Ahmed Sultan, Hesham El Gamal , 810
"... Abstract—We consider the design of cognitive Medium Access Control (MAC) protocols enabling an unlicensed (secondary) transmitter-receiver pair to communicate over the idle periods of a set of licensed channels, i.e., the primary network. The objective is to maximize data throughput while maintainin ..."
