SmartBAN addresses the five major features below: 1) Smart Body Area Networks (SmartBAN) Unified data represent

19、ation formats, semantic and open data model. 2) SmartBAN Data representation and transfer, service and application; Standardized interfaces, APIs and infrastructure for heterogeneity and interoperability management. 3) SmartBAN Measurements and Modelling of SmartBAN RF environment. 4) Low complexity

20、 MAC and routing for SmartBAN. 5) Enhanced, ultra-low power PHY for SmartBAN. The following technologies are also to be defined: smart control; network management; implant communications; security; and privacy mechanisms. SmartBAN takes a comprehensive view of BAN from lower layer (e.g. physical lay

21、er and MAC layer) to higher layer system aspects and end-to-end (e.g. heterogeneity management and semantic interoperability and monitoring and control). End-to-end connectivity (e.g. SmartBAN to Medical Centre or SmartBAN to SmartBAN) is illustrated by figure 1. Figure 1: Scope of SmartBAN SmartBAN

22、 facilitates the efficient use of multiple radio technologies. This will be handled in all the layers including semantic interoperabilities and a BAN coordinator will be introduced for that purpose (figure 2). This coordinator will also provide mandatory functionality related to routing and interact

23、ions with other application domains that includes e.g. SmartM2M, automotive, smart home environments. ETSI ETSI TR 103 394 V1.1.1 (2018-01) 6 Figure 2: Summary of the SmartBAN environment main constraints Figure 3 provides a an example of a possible future multi-radio (e.g. narrowband 2,4 GHz and UW

24、B). The controller may be e.g. a handset or other device while other, simpler devices (e.g. smart watch or wristband) may serve as a relay/bridge within the BAN offering enhanced performance/robustness (e.g. relay around hidden devices) as well as opening the door for optimized SmartBAN solutions wi

39、terogeneity Management 8.0 Introduction BANs are made of a growing number of small sensing devices and are used in multiple use cases for which data procurement, collection, monitoring and control are mandatory. Generally domain dedicated, those devices are provided by an increasing number of manufa

40、cturers, which leads to interoperability problems (e.g. heterogeneous interfaces and/or grounding, heterogeneous descriptions, profiles, models, etc.). Interoperability management is thus a SmartBAN key requirement and should be handled. Furthermore, data provided by these BANs are very heterogeneou

41、s because they are coming from sensing/actuating nodes with various abilities (e.g. different sensing ranges, formats, coding schemes, etc.). This entails managing data level heterogeneity. Therefore, data heterogeneity management is another SmartBAN key requirement that should also be handled. For

42、handling BAN interoperability management, the design of a BAN-dedicated open and extensible framework, provided with standardized APIs, for generic interactions with BAN devices (or nodes) and corresponding data/information, becomes mandatory. This kind of open middleware/framework will enable verti

43、cal interoperability within a given application domain, such as e.g. well-being, m-health, tele-health, safety/emergency, entertainment, etc. It will also ease the cross domain interworking of in particular devices, which represents a first step towards the horizontal management of BAN multiple vert

44、ical application domains. Finally, the SmartBAN open framework should also be provided with interworking components (entities, APIs or gateways) for allowing interactions with non SmartBAN enabled environments. Interoperability of multiple and new BAN technologies not only implies a generic intercon

45、nection between BANs components (sensors, actuators, relays, concentrators and hubs) but also a shared and mutual understanding of BAN devices and environment description, as well as of exchanged data format (syntactic and structural interoperability among frameworks). This is manageable through the

46、 use of a common and standardized metadata description format. All the aforementioned issues will be handled within ETSI TS 103 327 i.4. For handling data heterogeneity, the solution consists of the formalization and the specification of a shared semantic for SmartBANs, expressed within a common ope

47、n data model and provided with the associated ontology. This open data model and ontology will provide the required generic description for BAN entities and corresponding data (including monitoring and control ones). This data model, should be in particular designed for handling any kind of BAN devi

48、ces and measured data (which is still not the case of existing WSNs data models). The SmartBAN data model should also be sufficiently semantically rich for e.g. allowing similarity detection and conflict resolution. But this semantic enrichment of the SmartBAN data model should not be done at the ex

49、pense of the mandatory low complexity constraint of SmartBANs (i.e. right balance should be found between semantic richness and complexity). This then made also compulsory the design of a modular data model and ontology for SmartBANs. Furthermore, if SmartBAN automated monitoring and control functionalities want to be enabled, as well as if the design of new SmartBAN services and applications wants to be eased, service level data model should be addressed and added to the SmartBAN open data model and associ
