Wireless Sensor Network (WSN) has been widely used in many important areas. MAC protocols have a significant effect on the function of WSN. This paper introduced various important MAC protocols, analyzed the fundamental mechanism of each MAC protocol in details, and compared the characteristics and performances of each MAC protocol. Finally, the future research strategies and trends of MAC protocols...
Plant automation and control are mission-critical applications and require timely and reliable data delivery, which is difficult to provide using a wireless technology. This is especially more difficult in industrial environments with harsh radio conditions. In this paper we present a dynamic and distributed topology control algorithm for Wireless Sensor Networks for use in performance critical environments...
MAC protocol is of vital importance to the reliable communication of WSN for it schedules the limited wireless resources among sensor nodes. In this paper, focused on the intelligent transportation sensor network application requiring real-time transmission of a large amount of data, a MAC scheduling algorithm based on hybrid TDMA/FDMA scheme is proposed. The scheduling algorithm takes advantage of...
TDMA has been proposed as a MAC protocol for wireless sensor networks (WSNs) due to its efficiency in high WSN load. However, TDMA is plagued with shortcomings; we present modifications to TDMA that will allow for the same efficiency of TDMA, while allowing the network to conserve energy during times of low load (when there is no activity being detected). Recognizing that aggregation plays an essential...
In a wireless sensor network (WSN), interesting events are reported to the sink by the sensors in a distributed manner. Applications running at the sink require certain reliability in terms of events per unit time to be able to run satisfactorily. Individual report from sensor nodes is not important, but collective reports from sensor nodes of a region of interest of an application are crucial. Thus,...
TDMA is probably the best choice for an energy efficient multiple access protocol for wireless sensor networks. As such there exist many approaches of increased complexity, using different algorithms and combining information from other layers or multiple access techniques. There are many surveys detailing the protocols and their advantages and disadvantages, but we feel that they don't give a general...
In this paper, we propose a medium access control (MAC) protocol for supporting telematics service in the road environment, which requires the guarantee of a delay bound on end-to-end transmission and high transmission reliability in a multi-hop network. In order to guarantee a delay bound on end-to-end transmission and high transmission reliability in a multi-hop network, the proposed MAC adopts...
