“…There are some studies in the literature that integrate the CR and WBAN technologies. [16][17][18][19][20] However, the IEEE 802.15.6 standard and channel bonding technique have not been used in these studies. In this context, the proposed approach is the first study in the literature that uses the CR technology for 802.15.6-based WBAN.…”

“…In Ali et al, 16 a new CR-based Media Access Control (CR-MAC) protocol was developed for WBASNs using CR transmission, where sensor nodes are classified as critical and noncritical health information nodes. In Lee et al, 17 the authors proposed a protocol with energy efficiency and low latency by providing asynchronous and fast channel transition specially designed for WBAN with CR features. In Nhan et al, 18 an energy-efficient MAC that can work cognitively in high-noise environments was proposed for the WBASNs.…”

Today, developments in wireless technologies and the increase in disaster cases reveal the necessity of various wireless technologies cooperation. Several technologies are able to cooperate with each other for eHealth, IoT, and so forth applications in disaster cases with the pros and cons of today's communications. Wireless Body Area Networks (WBAN) and cognitive radio (CR) are promising technologies that can be used together to troubleshoot communication problems and make rescue operations successful in disaster situations. WBAN is a radio frequency-based wireless network technology that aims to monitor the functions and conditions of the human body through the sensor nodes that form a network. CR proposes solutions to current problems of wireless communications such as spectrum scarcity and inefficient use of the spectrum. In this study, CR-based WBAN architecture is proposed in disaster cases, and so the emergency, time-critical, and vital signs of WBAN users (endangered people and rescue team members) are able to reach the health unit or disaster management unit in an opportunistic way. CR technology is integrated with a WBAN architecture utilizing the CSMA/C-based IEEE 802.15.6 standard, and performance analysis is executed with the Riverbed Modeler simulation software. Furthermore, using the channel bonding technique, the throughput, the delay, the packet delivery ratios, and energy consumption ratios of the proposed architecture are investigated. According to the results, it was found that CR-based WBAN architecture was 25% more successful in energy efficiency and 5% more successful in packet delivery ratio with channel bonding technique than the traditional WBAN.

“…Essa abordagem tem o objetivo de iniciar uma comunicação entre a estação base e a rede corporal para evitar problemas de surdez, comuns em uma abordagem totalmente dinâmica. A partir desse contato inicial, o transmissor e receptor negociam qual canal de dados utilizar, o que evita maiores atrasos quando comparado a um processo de tentativa e erro para encontrar qual canal a estação base está sintonizada [Lee et al 2011].…”

“…Como consequência, essas redes apresentam altas latências e baixa transmissão [Fang et al 2010]. Para evitar que redes próximas utilizem o mesmo canal, diversos trabalhos propuseram técnicas de alocação de canais entre redes corporais co-localizadas [Doost-Mohammady and Chowdhury 2012, Phunchongharn et al 2010, Lee et al 2011. Essas técnicas permitem a utilização simultânea de diferentes canais pelas redes corporais para transmissão de dados, o que evita que as transmissões sofram tais interferências.…”

The advancement in electronics, wireless communications and integrated circuits has enabled the development of small low-power sensors and actuators that can be placed on, in or around the human body. A wireless body area network (WBAN) can be effectively used to deliver the sensory data to a central server, where it can be monitored, stored and analyzed. For more than a decade, cognitive radio (CR) technology has been widely adopted in wireless networks, as it utilizes the available spectra of licensed, as well as unlicensed bands. A cognitive radio body area network (CRBAN) is a CR-enabled WBAN. Unlike other wireless networks, CRBANs have specific requirements, such as being able to automatically sense their environments and to utilize unused, licensed spectra without interfering with licensed users, but existing protocols cannot fulfill them. In particular, the medium access control (MAC) layer plays a key role in cognitive radio functions, such as channel sensing, resource allocation, spectrum mobility and spectrum sharing. To address various application-specific requirements in CRBANs, several MAC protocols have been proposed in the literature. In this paper, we survey MAC protocols for CRBANs. We then compare the different MAC protocols with one another and discuss challenging open issues in the relevant research.
