A Study of MAC Protocols for WBANs
The seamless integration of low-power, miniaturised, invasive/non-invasive lightweight sensor nodes have contributed to the development of a proactive and unobtrusive Wireless Body Area Network (WBAN). A WBAN provides long-term health monitoring of a patient without any constraint on his/her normal dailylife activities. This monitoring requires the low-power operation of invasive/non-invasive s...
متن کاملEnergy-efficient MAC protocols for WBANs: Opportunities and challenges
Wireless body area networks (WBANs) are expected to play a significant role in smart healthcare systems. One of the most important attributes of WBANs is to increase network lifetime by introducing novel and low-power techniques on the energy-constrained sensor nodes. Medium access control (MAC) protocols play a significant role in determining the energy consumption in WBANs. Existing MAC proto...
متن کاملA survey: energy exhausting attacks in MAC protocols in WBANs
Because the sensors of wireless body area networks (WBANs) have limited battery power, many studies have focused on energy efficient medium access control (MAC) protocols to extend the lifetime of the sensors. In addition, WBANs face energy-exhausting attacks, which force the sensors to consume battery power partially or thoroughly. These attacks occur mainly in the MAC layer and threaten sever...
متن کاملAn Emergency Handling Scheme for Superframe-Structured MAC Protocols in WBANs
Wireless body area networks (WBANs) provide medical and/or consumer electronics (CE) services within the vicinity of a human body. In a WBAN environment, immediate and reliable data transmissions during an emergency situation should be supported for medical services. In this letter, we propose a flexible emergency handling scheme for WBAN MAC protocols. The proposed scheme can be applied to sup...
متن کاملOn the Development of Low Power MAC Protocol for WBANs
Current advances in wireless communication, microelectronics, semiconductor technologies, and intelligent sensors have contributed to the development of unobtrusive WBANs. These networks provide long term health monitoring of patients without any constraint in their normal activities. Traditional MAC protocols do not accommodate the assorted WBAN traffic requirements in a power efficient manner...
