Measuring the living condition and health status of users using small sensing devices and collecting the data of each user over wireless networks is expected to be a new trend in healthcare. Body Area Network (BAN) is an emerging area of personal data communications that will facilitate the capture of data and its collection. Although the IEEE 802.15.6 standard for wireless body area networks was...
In this paper we introduce medium access control (MAC) protocol defined by ETSI TC (technical committee) SmartBAN (smart body area network). The key features of the protocol are a two-channel concept with different channels for data and control traffic, and a unique Multi-use Channel Access as one alternative channel access mode. The two-channel concept provides fast channel acquisition and easy Hub...
A fully-integrated single-chip CMOS transceiver with MAC and PHY for 60GHz proximity wireless communication is presented. A 60GHz wireless communication single-chip transceiver has not yet been reported due to large power consumption issues. However, by limiting the application to high-throughput proximity transmission, thermal issues arising in a single-chip have been overcome. A 2GHz broadband OFDM...
This paper proposes two energy-efficient standby mode algorithms in short-range one-to-one 60 GHz millimeter wave (mmWave) communications. Among the many usage scenarios for mmWave radio, file downloading from kiosk terminals or peer-to-peer sync service with portable terminals are of great interest. For these portable terminals, the power consumption of standby mode as well as connection setup time...
This paper proposes a prioritized access opportunity exchange protocol for enhancing medium access control (MAC) efficiency in short-range one-to-one wireless communications on 60 GHz millimeter wave. A random back-off access protocol is widely spread for distributed wireless networks and is adopted in IEEE 802.11 WLAN standard. When many terminals try to access a wireless medium, the protocol works...
Millimeter-wave (mmWave) wireless systems are a focus of great interest for very high data transmission rate in a short range. Considering short-range communication with a range of the order of several tens of centimeters, only terminals present in this communication range will be influenced. In one-to-one communication, a simpler and more efficient access mechanism is required. Current CSMA/CA based...
