The physical world can be monitored by ubiquitous Internet of Things (IoT) devices through participatory sensing by which a huge amount of data is collected and analyzed in the cloud for hazard detection and response. In this paper, we propose a Trust as a Service (TaaS) cloud utility leveraging a cloud hierarchy for assessing service trustworthiness of IoT devices so as filter out untrustworth...

Emerging Internet of Things (IoT) systems consist of great numbers of heterogeneous physical entities that are interconnected via the Internet. These devices can continuously interact with the surrounding environment and be used for user applications that bene t human life in domains such as assisted living, e-health, transportation etc. In order to integrate the frontend physical things with I...

Over the past decade, we have witnessed the emergence of a bulk set of devices, from very different application domains interconnected via Internet to form what is commonly named Internet of Things (IoT). The IoT vision is grounded in the belief that all devices are able to interact seamlessly with each other anytime, anyplace, anywhere. However, devices communicate via a multitude of incompati...

The Internet of Things (IoT) is changing the way we interact with everyday objects. “Smart” devices will reduce energy use, keep our homes safe, and improve our health. However, as recent attacks have shown, these devices also create tremendous security vulnerabilities in our computing networks. Securing all of these devices is a daunting task. In this paper, we argue that IoT device communicat...

Devices are becoming increasingly interconnected; linked with each other and with humans. The internet of things(IoT) concept is currently used in machine to machine (M2M) applications like power, gas, and oil utilities transmission and transport. The most profound challenge that IoT faces is how to connect several very different devices into a network of things. In this regard, the standard fo...

Organizations are facing a new IT era of low-cost, small electronic devices with sensing, communications and computing capabilities, commonly known as the “Internet of Things” (IoT). Changes driven by the IoT will likely be far more profound than those brought about by previous IT eras. In particular, the digital data streams (DDSs) generated by the widespread adoption of IoT devices will creat...

The IoT is a domain in exponential growth: both the number of connected devices and the quantity of data they produce are increasing. The heterogeneity of technologies involved, and the diversity of domains impacted raise interoperability concerns. The semantic web principles and technologies are semantic interoperability providers, and ontologies like SSN have been used in several IoT projects...

The growing market for smart home IoT devices promises new conveniences for consumers while presenting new challenges for preserving privacy within the home. Many smart home devices have always-on sensors that capture users’ offline activities in their living spaces and transmit information about these activities on the Internet. In this paper, we demonstrate that an ISP or other network observ...

Internet of Things (IoT) is connecting billions of devices to the Internet. These IoT devices chain sensing, computation, and communication techniques, which facilitates remote data collection and analysis. wireless sensor networks (WSN) connect sensing devices together on a local network, thereby eliminating wires, which generate a large number of samples, creating a big data challenge. This I...

The proliferation of the Internet of Things (IoT) has since seen a growing interest in architectural design and adaptive frameworks to promote the connection between heterogeneous IoT devices and IoT systems. The most widely favoured software architecture in IoT is the Service Oriented Architecture (SOA), which aims to provide a loosely coupled systems to leverage the use and reuse of IoT servi...
