Internet of Thins is a paradigm in which things (devices) communicate with each other and with a cloud platform to perform a set of tasks includes monitoring and controlling the device or the surrounding environment. In this paper, we introduce the basic architecture of AssIUT IoT a remotely accessible testbed designed for IoT applications. The testbed adopts Experiment as a Service (EaaS) model as it provides a suitable and easy way to remotely implement experiments related to IoT applications. We provide details about the testbed design and architecture from hardware and software point of views. Also, we provide some examples of the experiments which can be implemented using our testbed.
