SD-MAC protocol for wireless sensor network energy consumption
2026
Energy efficiency remains a critical challenge in Wireless Sensor Networks (WSNs), especially under dynamic traffic conditions. Traditional MAC protocols such as S-MAC and T-MAC suffer from fixed sleep cycles and early sleep problems, limiting their adaptability and efficiency. This paper introduces a novel protocol, Sleep Duty-cycle MAC (SD-MAC), which dynamically adjusts active listening periods based on real-time network traffic, thereby reducing idle listening and improving energy utilization. Unlike conventional approaches, SD-MAC incorporates a traffic-aware scheduling mechanism with dynamically tunable duty cycles, allowing sensor nodes to enter low-power sleep states without compromising data transmission reliability. The protocol is evaluated through extensive simulations using NS-2 under diverse traffic scenarios, with statistically validated performance metrics. Results demonstrate that SD-MAC achieves up to 10% more energy savings and higher throughput than T-MAC and outperforms several recent MAC protocols in terms of energy consumption, medium access delay, and packet delivery rate. These findings confirm the effectiveness of SD-MAC in enabling scalable and energy-efficient WSNs, particularly in low and medium-traffic environments.

Traffic density around the globe is increasing on a day-to-day basis, resulting in more accidents, congestion, and pollution. The dynamic vehicular environment induces challenges in designing an efficient and reliable protocol for communication. Timely delivery of safety and non-safety messages is necessary for traffic congestion control and for avoiding road mishaps. For efficient resource sharing and optimized channel utilization, the media access control (MAC) protocol plays a vital role. An efficient MAC protocol design can provide fair channel access and can delay constraint safety message dissemination, improving road safety. This paper reviews the applications, characteristics, and challenges faced in the design of MAC protocols. A classification of the MAC protocol is presented based on contention mechanisms and channel access. The classification based on contention is oriented as contention-based, contention-free, and hybrid, whereas the classification based on channel access is categorized as distributed, centralized, cluster-based, cooperative, token-based, and random access. These are further sub-classified as single-channel and multi-channel, based on the type of channel resources they utilize. This paper gives an analysis of the objectives, mechanisms, advantages/disadvantages, and simulators used in specified protocols. Finally, the paper concludes with a discussion on the future scope and open challenges for improving the MAC protocol design.

DCO-MAC: A Hybrid MAC Protocol for Data Collection in Underwater Acoustic Sensor Networks
2018
In underwater acoustic sensor networks (UASNs), medium access control (MAC) is an important issue because of its potentially significant effect on the network performance. However, designing a suitable MAC protocol for the UASN is challenging because of the specific characteristics of the underwater acoustic channel and network, such as limited available bandwidth, long propagation delay, high bit-error-rate, and sparse network topology. In addition, as the traffic load is non-uniformly distributed in a UASN for data collection, it is essential to consider the application feature for the MAC protocol. In this paper, we propose a MAC protocol in a data-collection-oriented UASN, abbreviated as the DCO-MAC protocol. In the proposed protocol, the network is partitioned into two kinds of sub-networks according to the traffic load. A contention-based MAC protocol is used in the sub-network with a light traffic load, while a reservation-based MAC protocol is used in the sub-network with a heavy traffic load. Meanwhile, the DCO-MAC protocol supports the access of mobile nodes. The theoretical analysis and simulation results demonstrate that, in a UASN for data collection, the proposed MAC protocol outperforms the other existing MAC protocols, in terms of the network throughput, end-to-end packet delay, energy overhead, and fairness.

Fleetwood Mac : the complete illustrated history
This is the first-ever complete, illustrated history of Fleetwood Mac, the legendary band that has sold more than 48 million records worldwide. From this British-American band's blues origins in the 1960s to its pop superstardom in the 1970s and 1980s to its 2015 reunion, Fleetwood Mac has endeared itself to audiences worldwide. Fleetwood Mac: The Complete Illustrated History covers the band's illustrious career, highlighting details that will surprise even the most loyal fans. With a career that began nearly fifty years ago and yielded seventeen studio albums, Fleetwood Mac has had a rollercoaster career, detailed here through a carefully researched text and myriad photographs and memorabilia, including some rare and little-seen items. The band's most popular lineup includes drummer Mick Fleetwood, bassist John McVie, keyboardist and vocalist Christine McVie, guitarist and vocalist Lindsey Buckingham, and singer Stevie Nicks, but its members have shifted over the years since Fleetwood Mac began in 1967. And although the band's superstar phase in the 1970s is most familiar to the public, Fleetwood Mac's roots were in the blues, and the band evolved in fits and starts before finding popular success. Fleetwood Mac: The Complete Illustrated History documents their entire story, including the troubled circumstances that led to the 1970 withdrawal of the band's original guitarist, Peter Green, as well as the broken marriage of John and Christine McVie and the romantic breakup of Stevie Nicks and Lindsey Buckingham that threatened to split the group even as they were recording one of the biggest albums of all time, Rumours. This is the whole story of one of rock and roll's greatest bands.
Review of MAC Protocols for Vehicular Ad Hoc Networks
2020
Vehicular ad hoc networks (VANETs) need to support the timely end-to-end transmissions of safety and non-safety messages. Medium access control (MAC) protocols can ensure fair and efficient sharing of channel resources among multiple vehicles for VANETs, which can provide timely packet transmissions and significantly improve road safety. In this paper, we review the standards of some countries for VANETs. Then, we divide the MAC protocols proposed for VANETs into single-channel MAC protocols and multi-channel MAC protocols according to the number of physical occupied spectrum resources. Both are further discussed based on their hierarchical structures, i.e., distributed and centralized structures. General design and optimization mechanisms of these commonly used MAC protocols for VANETs are reviewed. From the viewpoint of 7 aspects, we compare the advantages and disadvantages of these typical MAC protocols. Finally, we discuss the open issues to improve the MAC performance and future work on MAC design for VANETs.

low-priority traffic
2017
Recently, wireless body area networks (WBANs) have attracted significant consideration in ubiquitous healthcare. A number of medium access control (MAC) protocols, primarily derived from the superframe structure of the IEEE 802.15.4, have been proposed in literature. These MAC protocols aim to provide quality of service (QoS) by prioritizing different traffic types in WBANs. A contention access period (CAP)with high contention in priority-based MAC protocols can result in higher number of collisions and retransmissions. During CAP, traffic classes with higher priority are dominant over low-priority traffic; this has led to starvation of low-priority traffic, thus adversely affecting WBAN throughput, delay, and energy consumption. Hence, this paper proposes a traffic-adaptive priority-based superframe structure that is able to reduce contention in the CAP period, and provides a fair chance for low-priority traffic. Simulation results in ns-3 demonstrate that the proposed MAC protocol, called traffic- adaptive priority-based MAC (TAP-MAC), achieves low energy consumption, high throughput, and low latency compared to the IEEE 802.15.4 standard, and the most recent priority-based MAC protocol, called priority-based MAC protocol (PA-MAC).
