A personal connected health system for the Internet of Things based on the Constrained Application Protocol

Display Omitted We present a system that enables Personal Health Devices to share information in home networks and with the Internet.The Constrained Application Protocol (CoAP) is used as underlying protocol.The CoAP communication model was adapted to the ISO/IEEE 11073 model in the proposed system.Results showed how the network overhead is around 50% lighter when compared to other protocols.Interoperability experiments demonstrated how the proposed solution can work with legacy systems. The increasing costs of healthcare along with the increasing availability of new Personal Health Devices (PHDs) are the ingredients of the connected health vision. Also, a growing number of consumer electronic and mobile devices are becoming capable of taking the role of a health gateway, thus operating as a data collector for PHDs. In this context, we present a system that enables PHDs to share information in home networks and with the Internet based on a new Internet of Things protocol, namely the Constrained Application Protocol (CoAP). CoAP is used along with the IEEE 11073 family of standards, which is the main exchange data model for PHD communication. We discuss how the proposed system can be integrated to other connected health systems, such as a Universal Plug and Play healthcare system. We detail how the CoAP communication model was adapted to the IEEE 11073 model. We also present a real PHD prototype and its evaluation results. These results demonstrated the feasibility of the proposed solution, showing how its network overhead is around 50% lighter when compared to other protocols. Finally, we tested the proposed solution based on different scenarios, including a proof-of-concept integration with a service in the cloud, using different wireless physical interfaces.

Integrating MQTT and ISO/IEEE 11073 for health information sharing in the Internet of Things

The Internet of Things (IoT) paradigm allows small and resource constrained devices to send data through complex networks like the Internet. Bringing the IoT paradigm to the healthcare area, we can expand the connected health vision, enabling new Personal Health Devices (PHD) to share health information directly through the Internet. In this paper we explore the use of the MQTT (Message Queue Telemetry Transport) lightweight protocol together with the ISO/IEEE 11073 standard. We present new ways of connecting PHDs in home networks and the Internet by the use of MQTT Brokers, which will reduce the amount of data traffic.

Granola: A location and bandwidth aware protocol for Mobile Video on-Demand systems

Due the development of new wireless technologies and the advent of new mobile devices, new services and applications are necessary to supply the needs of the users of these devices. Video on-Demand (VoD) services have become one of these services. In this paper we present a P2P Mobile Video on-Demand (VoD) Protocol for mobile devices. Due to different possible communication interfaces that are available for mobile devices, we considerer that they can be in networks with different throughput characteristics, and also, they can be distributed through the Internet. Therefore, the proposed protocol allows the building of content distribution trees in the application layer considering two major aspects related to mobility: the bandwidth available that the mobile device can share with the network, and; the relative position of the mobile device in the network. Also it is presented simulation results of our protocol, and a performance analysis against the traditional Client-Server design.

IEEE 11073 and connected health: Preparing personal health devices for the Internet

The Internet of Things paradigm enables a new set of Internet applications and services. Some of these new applications are related with healthcare and the Connected Health vision. On the other hand, the increasing availability of new connected Personal Health Devices enables a new type of information to be available in the Internet: health information. In this context, this paper presents and discusses current Connected Health solutions, and how they fit into IoT paradigm. It is presented how IEEE 11073 family of standards may enable a truly and interoperable health IoT architecture. It is presented a IEEE 11073 implementation aimed at portable devices, namely Antidote. Also a proposal that uses TCP as IEEE 11073 transport method is also shown. Moreover, it is presented a work in progress solution to enable PHDs to connect directly to the Internet using IEEE 11073 and CoAP protocol.

Integrating IEEE 11073 and constrained application protocol for personal health devices

Nowadays, new challenges are presenting new opportunities for healthcare services in the Internet. The increasing availability of connected Personal Health Devices (PHDs) enables a new type of information to be available in the Internet: health information. However, most of these devices use proprietary protocols, creating vertical solutions where one device just talks to one service. In this context, this paper presents a proposal for the use of the Constrained Application Protocol (CoAP) for PHDs communication, using IEEE 11073 as base health protocol. It is discussed how to carry IEEE 11073 information over CoAP messages and, at the end, evaluation results are presented in comparison with other transport mechanisms.

Standard-based and distributed health information sharing for mHealth IoT systems

The increasing availability of connected Personal Health Devices (PHDs) enables a new type of information to be available in the Internet: health information. Most of these devices have specific ways to connect and share information to the Internet through gateways or health managers, creating vertical solutions where one device just talks to one health service. In this context, this paper proposes an architecture that considers the use of different types of health managers and gateways, but keeping interoperability by the use of widely adopted standards. The main contribution of this work is the distribution of health managers in different locations, such as mobile devices and cloud applications, enabling the use of a single health service for different types of PHDs. The ISO/IEEE 11073 standard is used as core technology, enabling the transport of PHD information over different technologies and protocols. We also present a new classification of health managers based on requirements of legacy m-health services. In conclusion, the results of the integration with a real cloud-based connected health system are presented and evaluated.

Seamless access of home theater personal computers for mobile devices

This paper presents the MoMPt project, an open source project developed to allow access to multimedia content and to control multiple HTPCs remotely using mobile devices. The main contribution in the context of this project is its reference design, which allows the access of HTPC functionalities using different technologies, such as UPnP and XML-RPC. In this paper the reference design as well as its main components are detailed. Also, we describe one developed solution for the MediaPortal HTPC. It is discussed how it was developed, and the evaluation scenario with mobile devices, more specifically an Internet Tablet.

BRisa UPnP A/V Framework

This paper presents the BRisa UPnP A/V framework. BRisa is a framework that allows users to discover multimedia devices, share, search and render multimedia content over the local networks or remotely through the Internet. BRisa has been developed using UPnP specifications, which makes use of standard Internet protocols and services, such as HTTP, UDP and SOAP. BRisa is composed of three main applications: the BRisa Media Server, the BRisa media renderer and the BRisa control point, each of them plays a specific role in our entire UPnP solution. In this paper we briefly describe our UPnP implementation and discuss a set of features implemented to share audio/video/image in a computer network. We also explain the application of our approach to resource limited devices, more specifically for the N800 Nokia Internet Tablet.

UPnP and IEEE 11073: Integrating personal health devices in home networks

Personal Health Devices (PHDs) with wireless technologies are becoming popular for remotely monitoring patients. However, although these devices are portable and mostly used at home, their integration with Consumer Electronics (CE) devices and networks is still in the earlier steps. This article presents a reference architecture that integrates at home PHDs and CE devices based on the UPnP (Universal Plug and Play) technology and the IEEE 11073 set of standards. This article introduces a UPnP device architecture for personal m-Health (mobile Health), describing how different types of devices interact to exchange personal health information. One of the main features of this work is the use of widely adopted data formats, such as eXtended Markup Language (XML) for health information exchange based on IEEE 11073 data model. Such approach enables web based CE networks, such as UPnP, to interact with PHD devices efficiently.

A Standard-Based and Context-Aware Architecture for Personal Healthcare Smart Gateways

The rising availability of Personal Health Devices (PHDs) capable of Personal Network Area (PAN) communication and the desire of keeping a high quality of life are the ingredients of the Connected Health vision. In parallel, a growing number of personal and portable devices, like smartphones and tablet computers, are becoming capable of taking the role of health gateway, that is, a data collector for the sensor PHDs. However, as the number of PHDs increase, the number of other peripherals connected in PAN also increases. Therefore, PHDs are now competing for medium access with other devices, decreasing the Quality of Service (QoS) of health applications in the PAN. In this article we present a reference architecture to prioritize PHD connections based on their state and requirements, creating a healthcare Smart Gateway. Healthcare context information is extracted by observing the traffic through the gateway. A standard-based approach was used to identify health traffic based on ISO/IEEE 11073 family of standards. A reference implementation was developed showing the relevance of the problem and how the proposed architecture can assist in the prioritization. The reference Smart Gateway solution was integrated with a Connected Health System for the Internet of Things, validating its use in a real case scenario.
