This paper presents a wakeup receiver for latency-critical IoT applications in 90nm CMOS, which is fully compliant to many popular IoT wireless standards with constant envelope modulations, such as Bluetooth Low Energy and IEEE802.15.4. Paired with a standard-compliant transmitter, the proposed wakeup receiver method minimizes the overhead in system power, area and complexity. The proposed 2-dimensional...
One of the major concerns for the development of Wireless Body Area Network (WBAN) is to increase the network lifetime. IEEE 802.15.4 standard for Medium Access Control (MAC) layer can be used for energy efficient and reliable transmission by modifying the different control parameters. Such a modification is very difficult, because an accurate model for the influence of these control parameters of...
One of key attributes of WBAN is to extend the network lifetime, which can be achieved by adjusting the wakeup and sleep modes of the sensor nodes. Traditional low-power methods such as channel polling and periodic duty cycling are unable to satisfy WBANs requirements due to idle listening, collision, and control packet overhead problems. In this paper, we propose an RFID-enabled MAC protocol (RMAC)...
A 0.13µm CMOS low power wake-up radio is presented. The wake-up radio operates with −41dBm sensitivity at 915MHz using OOK modulation with a data rate of 100kbps while consuming 98nW active power, 11pW sleep power, and has an energy efficiency of 0.98pJ/bit. The wake-up radio occupies 0.03mm2 and uses two off-chip components (an inductor and a capacitor). All biasing and calibration for process variation...
Body sensor networks (BSNs) are emerging cyber–physical systems that promise to improve quality of life through improved healthcare, augmented sensing and actuation for the disabled, independent living for the elderly, and reduced healthcare costs. However, the physical nature of BSNs introduces new challenges. The human body is a highly dynamic physical environment that creates constantly changing...
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 the performance of such a network. Power consumption...
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 paper, we propose a MAC protocol for WBAN using...
Applications of sensor networks in healthcare have undergone major changes in recent times. Implanted wireless sensor devices inside the human body to monitor the activities are a reality now. A new field called the Wireless Body Area Networks (WBAN or BAN) has emerged as a hot research area. To fulfill the needs for a common standard and solve the issues in this emerging field, IEEE has proposed...
Wakeup radio schemes are employed to improve the energy efficiency in wireless sensor networks. In this paper, an analytical model is formulated to make a justified comparison between two different wakeup schemes, one-channel wakeup radio and two-channel wakeup radio. As the key measurement, energy efficiency is studied by taking the latency requirement as the main constraint. Moreover, the probabilities...
