Wireless sensor networks are widely used for healthcare applications. A new field known as wireless body area networks (WBAN) has emerged to support this area. An energy efficient medium access control (MAC) protocol can increase the performance of such a network. The major requirements for a WBAN MAC protocol are energy efficiency and low delay. In this(More)
The IEEE 802.15.4 standard is a short range wireless technology. As a revision to this standard, IEEE 802.15.4a introduces new options for PHY (physical layer) to enable ranging. In this paper, we investigate the theoretical maximum throughput and minimum delay of the un-slotted version of 802.15.4a using CSS (Chirp Spread Spectrum) PHY. The throughput and(More)
Wireless Body Area Networks (WBANs) consist of a limited number of battery operated nodes that are used to monitor the vital signs of a patient over long periods of time without restricting the patient's movements. They are an easy and fast way to diagnose the patient's status and to consult the doctor. Device as well as network lifetime are among the most(More)
—Recent advances in Micro-Electro-Mechanical Systems (MEMS) technology, integrated circuits, and wireless communication have allowed the realization of Wireless Body Area Networks (WBANs). WBANs promise unobtrusive ambulatory health monitoring for a long period of time and provide real-time updates of the patient's status to the physician. They are widely(More)
Applications of wearable and implanted wireless sensor devices are hot research area. A specialized field called the body area networks (BAN) has emerged to support this area. Managing and controlling such a network is a challenging task. An efficient media access control (MAC) protocol to handle proper management of media access can considerably improve(More)
We investigate the maximum throughput and minimum delay for the unlostted version of the IEEE 802.15.4a using Ultra Wide Band (UWB). The throughput and delay limits are calculated for different data rates along with the formulae. UWB based 802.15.4a can achieve maximum throughput of 701 Kbps with a data rate of 851 Kbps.
Telemedicine is the way to provide better health care facilities to the people of the underprivileged unprocurable areas. As constraints on time and resources makes face to face consultation increasingly dearly-won, and telemedicine has the potential to produce major efficiencies in the symptomatic process. Therefore the goal of current research is to truss(More)
Body Area Network (BAN) is a collection of low-power, miniaturised, and intelligent sensor nodes that are used for unobtrusive and ambulatory health monitoring of a patient without any additional constraints. These nodes operate on different frequency bands or Multiple Physical Layers (Multi-PHYs). Additionally, some BAN applications demand a logical(More)
