In the past few years, the viability of the Internet of Things (IoT) technology has been demonstrated, leading to increased possibilities for novel human-centric services in the smart cities. This development has resulted in numerous approaches being proposed for harnessing IoT for smart city applications. Having received a significant attention by the research community and industry, IoT adapt...

The Internet of Things (IoT) is defined as a global network that links together living and/or non-living entities, such as people, animals, software, physical objects or devices. These entities can interact with each other, gather, provide or transmit information to the IoT. Although the Internet of Things is a relatively new concept, various platforms are already available. Some of them are op...

This paper presents a survey of current energy efficient technologies that could drive the IoT revolution while examining critical areas for energy improvements in IoT sensor nodes. The paper reviews improvements in emerging energy techniques which promise to revolutionize the IoT landscape. Moreover, the current work also studies the sources of energy consumption by the IoT sensor nodes in a n...

13 This paper presents the state-of-art of Internet of Things (IoT), an enabler of 14 new forms of communication between people and things, and between things. 15 The main strength of IoT concept is the high influence it has to everyday life 16 by creating new dimension to the world, resembling to what the Internet once 17 did. This paper describes the definitions of IoT, summarizes its main 18...

We investigate the performance of Internet-ofThings (IoT) networks under passive attacks from eavesdroppers capable of monitoring individual links. An IoT network with multiple sensor classes is studied where every sensor class has a local access point (LAP) which are connected to one or more small cell base-station access points (SAP) which in turn are connected to a central cloud access point...

Many Internet of Things (IoT) services utilize an IoT access network to connect small devices with remote servers. They can share an access network with standard communication technology, such as IEEE 802.11ah. However, an authentication and key management (AKM) mechanism for resource constrained IoT devices using IEEE 802.11ah has not been proposed as yet. We therefore propose a new AKM mechan...

The Internet-of-Things (IoT) has quickly evolved to a new appified era where third-party developers can write apps for IoT platforms using programming frameworks. Like other appified platforms, e.g., the smartphone platform, the permission system plays an important role in platform security. However, design flaws in current IoT platform permission models have been reported recently, exposing us...

Semantics for the IoT domain have been already introduced in several semantic interoperability approaches, towards supporting the (semi-)automated deployment of generic IoT applications in environments where heterogeneous third-party IoT devices are deployed. Depending on the level of interoperability, an application may have to ‘decide’ which IoT devices in that environment are trustworthy for...

Emerging cloud-centric Internet of Things (IoT) system relies on distant data centers to manage the entire processes, which raises the issue of latency. To address the issue, researchers have introduced the Edge computing methodologies that carry out computation closer to the edge network of IoT system. Among the numerous Edge computing approaches, Mist computing paradigm emphasises the mechani...

The Internet of Things – IoT – is a new paradigm in technology that allows most physical ‘things’ to contact each other. Trust between IoT devices is a critical factor. Trust in the IoT environment can be modeled using various approaches, such as confidence level and reputation parameters. Furthermore, trust is an important element in engineering reliable and scalable networks. In this paper, w...
