TL;DR: A novel mobile gateway solution for a ubiquitous mobile health scenario, in which information gathered from a body sensor network is used by an IPA belonging to another person, typically mentioned to as caretaker is proposed.
Abstract: The wide dissemination of Internet around the world changed the way people communicate among them. The evolution of the information and communication technologies (ICT) or artificial intelligence (AI) allowed the creation of new types of services involving electronic devices with huge potential. The emergence of intelligent personal assistants (IPAs) is one of such potential example. Combining the IPA concept with the recent paradigm of Internet of Things (IoT), offers new possibilities and new services to end users, since they could learn more about other entities present in the surrounding environment. This paper proposes a novel mobile gateway solution for a ubiquitous mobile health scenario, in which information gathered from a body sensor network (BSN) is used by an IPA belonging to another person, typically mentioned to as caretaker. The mobile gateway receives real time information related to location, heart rate, and possible falls of the monitored person and acts as a communication channel between the BSN sensors and the IPA platform. Furthermore, the paper presents a performance evaluation study of the proposed mobile IoT-based gateway demonstrating and validating its feasibility.

TL;DR: The results show that the development of virtual assistants is actually more complex than it was initially believed, and that a more consolidated approach is necessary to define the best method of development for virtual assistants.
Abstract: Virtual assistants are becoming more common today as access to this technology has become cheaper and more affordable to the common consumer. As a result of this increase in demand, a component based software engineering approach may be more practical in the future development of these systems. This article presents a study of the current state of the research on component based software engineering and service principles in virtual assistants. The main motivation for this research is that there just is not any comparative study on how component-driven development might benefit our virtual assistants, especially those with voice interaction. This study is limited to papers that go into detail about the development of intelligent personal assistants and the entities that comprise them. Due to the nature of virtual assistants, we initially assumed that many of them would primarily be made of various software components. However, our results show that the development of virtual assistants is actually more complex than we initially believed, and that a more consolidated approach is necessary to define the best method of development for virtual assistants.

TL;DR: An efficient and adaptive failure detection and recovery protocol for an ambient service management platform, in which failures are detected efficiently with a novel rotating roll-call algorithm without a centralized monitor is proposed to maintain network stability.
Abstract: A considerable number of studies have been made on ambient service management platform for smart home environments. Few of them addressed the robustness issue, which is fundamental for such environments. Robustness is critical because there are usually services that are critical to the habitants health and life in Smart Homes. In this paper, we propose an efficient and adaptive failure detection and recovery protocol for an ambient service management platform, in which failures are detected efficiently with a novel rotating roll-call algorithm without a centralized monitor. Adaptive techniques are also proposed to maintain network stability. The analysis and experiment results show that the proposed solution is capable of detecting software failures efficiently without causing network instability, hence preserving robustness of an ambient service platform at home.

TL;DR: A novel architecture model for IoT with the help of Semantic Fusion Model (SFM) is presented, which introduces the use of Smart Semantic framework to encapsulate the processed information from sensor networks.
Abstract: Internet-of-Things (IoT) is the convergence of Internet with RFID, Sensor and smart objects. IoT can be defined as “things belonging to the Internet” to supply and access all of real-world information. Billions of devices are expected to be associated into the system and that shall require huge distribution of networks as well as the process of transforming raw data into meaningful inferences. IoT is the biggest promise of the technology today, but still lacking a novel mechanism, which can be perceived through the lenses of Internet, things and semantic vision. This paper presents a novel architecture model for IoT with the help of Semantic Fusion Model (SFM). This architecture introduces the use of Smart Semantic framework to encapsulate the processed information from sensor networks. The smart embedded system is having semantic logic and semantic value based Information to make the system an intelligent system. This paper presents a discussion on Internet oriented applications, services, visual aspect and challenges for Internet of things using RFID, 6lowpan and sensor networks.

Abstract: The Internet of Things presents the user with a novel means of communicating with the Web world through ubiquitous object-enabled networks. Cloud Computing enables a convenient, on demand and scalable network access to a shared pool of configurable computing resources. This paper mainly focuses on a common approach to integrate the Internet of Things (IoT) and Cloud Computing under the name of CloudThings architecture. We review the state of the art for integrating Cloud Computing and the Internet of Things. We examine an IoT-enabled smart home scenario to analyze the IoT application requirements. We also propose the CloudThings architecture, a Cloud-based Internet of Things platform which accommodates CloudThings IaaS, PaaS, and SaaS for accelerating IoT application, development, and management. Moreover, we present our progress in developing the CloudThings architecture, followed by a conclusion.

TL;DR: Results from experiments and real-world tests show that the proposed architecture can support sample rates of up to several kHz while enabling sensor data to be transmitted to SOA services in real time, proving that the use of SOA, and Restful web services in particular, is feasible on resource-constrained platforms while supporting true mobility.
Abstract: The number of small embedded devices connected to the Internet is increasing. This growth is mostly due to the large number of Internet of Things (IoT) deployments, with applications such as: industrial monitoring, home automation, and others. One common aspect with the majority of application areas is the lack of mobility. Most IoT devices are stationary and often use IEEE 802.15.4/6LoWPAN solutions. When a high level of mobility is required, the use of IEEE 802.15.4 is not possible without adding additional hardware for the user to carry. In this article, a holistic network architecture consisting of heterogeneous devices is presented. The architecture is composed of Embedded Internet Systems (EIS) and uses standard communication protocols. One important feature is the use of the Service-oriented architecture (SOA) paradigm. The use of SOA, by utilization of the CoAP protocol and standard services, enables the proposed architecture to exchange sensor- and actuator data with an Internet-based cloud as well as a user's local cloud consisting of sensor IoT devices, smart phones and laptops. Another component of the architecture is a web-based human-machine interface for configuration, monitoring and visualization of sensor and actuator data using emerging web technologies for structured data processing. Results from experiments and real-world tests show that the proposed architecture can support sample rates of up to several kHz while enabling sensor data to be transmitted to SOA services in real time. This proves that the use of SOA, and Restful web services in particular, is feasible on resource-constrained platforms while supporting true mobility.

01 Jan 2010TL;DR: The main objective is to create more intelligent and more human alike IPA agents, enhancing the current abilities that these software agents provide.
Abstract: Intelligent Personal Assistant (IPA) agents are software agents which assist users in performing specific tasks. They should be able to communicate, cooperate, discuss, and guide people. This paper presents a proposal to add Semantic Web Knowledge to IPA agents. In our solution, the IPA agent has a modular knowledge organization composed by four differentiated areas: (i) the rational area, which adds semantic web knowledge, (ii) the association area, which simplifies building appropriate responses, (iii) the commonsense area, which provides commonsense responses, and (iv) the behavioral area, which allows IPA agents to show empathy. Our main objective is to create more intelligent and more human alike IPA agents, enhancing the current abilities that these software agents provide.

TL;DR: This paper proposes a model for WSNs monitoring based on a REST Web service and XML messages to provide a mobile ubiquitous approach for W SN monitoring and shows that proposed solution is able to collect and present data in a mobile environment, and it is ready for use.
Abstract: Wireless sensor networks (WSNs) belong to emerging technologies where network devices can interact with the surrounding environment by sensing physical parameters. Recently, with the dissemination of mobile devices to Internet connectivity, users can interact with sensor networks and collect environmental data, anytime, anywhere using user-friendly mobile applications. Following the Internet of Things vision, the integration of all sorts of Internet-based devices is considered a big challenge. New infrastructures are required in order to interconnect these devices independently of the used technologies. This paper proposes a model for WSNs monitoring based on a REST Web service and XML messages to provide a mobile ubiquitous approach for WSN monitoring. Data collected from a WSN is stored in a database. Then, mobile clients send XML based messages to a HTTP server through a well-defined REST interface, requesting WSN collected data. A WSN laboratory test bed was used to perform the evaluation, demonstration, and validation of the proposed model. Results show that proposed solution is able to collect and present data in a mobile environment, and it is ready for use.
