Abstract
This paper presents a condensed review of the European smart body area network (BAN) standardization work and its already published standards. The work is carried out under the ETSI Technical Committee (TC) SmartBAN. The goal of ETSI TC SmartBAN is to define and develop new European BAN standards; fostering the successful market adoption of wireless BAN technology by providing a standardized way to bring new interoperable products into the health, medical, sport, leisure and IoT markets, targeting to global exploitation. TC SmartBAN covers wireless communications, especially the physical and medium access control layers, associated security, semantic interoperability and open data representation, which are necessary features in the data transmissions, as well as building blocks of the future smart coordinator. The use of smart coordinator centralizes the network intelligence to the hub, which enables implementation of simple nodes. The SmartBAN approach will be computationally light, and it supports reliable operations across heterogeneous networks. Due to the semantic approach in all functional levels, SmartBAN also supports high interoperability. For emergency traffic, SmartBAN provides different priority classes and fast channel access associated with a low latency. Novel concept adopted in the SmartBAN for high-priority traffic is a multi-use channel access, which can also improve the spectral efficiency. Not only on-body nodes and applications, TC SmartBAN is considering in-body communications for capsule endoscopy. In addition, SmartBAN collaborates with other standardization groups, such as oneM2M and AIOTI, to widen the impact of its work.
Highlights
The Internet of Things (IoT) business is currently growing exponentially and the use of wearable electronics and body sensors/devices is expanding rapidly along with it
A key feature of SmartBAN today, which differentiates it with respect to its main competitors, is the support for operations across heterogeneous networks with enhanced interoperability and connectivity options
A unique channel access solution introduced in the SmartBAN is the Multi-use Channel Access (MCA), which can be used in scheduled access period (SAP), as well as in control and management period (C/M) period
Summary
The Internet of Things (IoT) business is currently growing exponentially and the use of wearable electronics and body sensors/devices is expanding rapidly along with it. BAN use cases are expected to increasingly demand secure and privacy preserving solutions, jointly optimized for low power, low latency, robust operations, and the ability to interact with embedded intelligence and heterogeneous environments. SmartBAN provides semantic and data analytic enablers, e.g., semantic discovery and reasoning/rules In the future, such features will be become part of the smart coordinator or hub (e.g., handset, watch or even wristband). A key feature of SmartBAN today, which differentiates it with respect to its main competitors, is the support for operations across heterogeneous networks with enhanced interoperability and connectivity options. This feature is exploited in all defined data, network and semantic IoT interoperability levels. These payload sizes are computed for uncoded MPDU transmissions and further details about the calculations are given in [7]
