A Mutual Authentication Method for Internet of Things

Today, we are witnessing the expansion of various Internet of Things (IoT) applications and services such as surveillance and health. These services are delivered to users via smart devices anywhere and anytime. Forecasts show that the IoT, which is controlled online in the user environment, will reach 25 billion devices worldwide by 2020. Data security is one of the main concerns in the IoT. ...

A Cellular-type Protocol Innovation for the Internet of Things

Things That Twitter: Social Networks and the Internet of Things

In this paper we investigate on the potential of combining social and technical networks to collaboratively provide services to both human users and technical systems. In the Internet of Things (IoT), things talk and exchange information to realize the vision of future pervasive computing environments. The common physical and social space emerges by the objects’ ability to interconnect, not onl...

A Survey of Anomaly Detection Approaches in Internet of Things

Internet of Things is an ever-growing network of heterogeneous and constraint nodes which are connected to each other and the Internet. Security plays an important role in such networks. Experience has proved that encryption and authentication are not enough for the security of networks and an Intrusion Detection System is required to detect and to prevent attacks from malicious nodes. In this ...

Passive Sensors for Long Duration Internet of Things Networks

In this work, three different concepts are used to develop a fully passive sensor that is capable of measuring different types of data. The sensor was supplied by Wireless Power Transmission (WPT). Communication between the sensor and reader is established by a backscatter, and to ensure minimum energy consumption, low power techniques are used. In a simplistic way, the process starts by the tr...
