Abstract
The correct implementation and behavior of Internet of Things (IoT) applications are seldom investigated in the literature. This paper shows how the simulation mechanism can be integrated well into an IoT application development platform for correct implementation and behavior investigation. We use an IoT application development platform called IoTtalk as an example to describe how the simulation mechanism called SimTalk can be built into this IoT platform. We first elaborate on how to implement the simulator for an input IoT device (a sensor). Then we describe how an output IoT device (an actuator) can be simulated by an animated simulator. We use a smart farm application to show how the simulated sensors are used for correct implementation. We use applications including interactive art (skeleton art and water dance) and the pendulum physics experiment as examples to illustrate how IoT application behavior investigation can be achieved in SimTalk. As the main outcome of this paper, the SimTalk simulation codes can be directly reused for real IoT applications. Furthermore, SimTalk is integrated well with an IoT application verification tool in order to formally verify the IoT application configuration. Such features have not been found in any IoT simulators in the world.

Summary
Many smart applications have been developed with Internet of Things (IoT) technology, including home automation [1], a smart aquarium [2,3], an intelligent campus [4,5], precision agriculture [6,7], interactive art and entertainment [8,9,10], and more It is seldom mentioned how they are correctly implemented, especially for the existing or envisioned applications in remote sensing. To resolve this issue, this paper proposes SimTalk based on an IoT development platform called. After an IoT service has been developed, IoTtalk GUI binds the network application program with the real sensors and the actuators with a button click.
