DoS-IL: A Domain Specific Internet of Things Language for Resource Constrained Devices

Abstract

The common approach enabling a resource constrained device to get connected to the Internet is through programming instructions and transferring it to an embedded device. This procedure involves various tools and cross-compiling of the code depending on the platform architecture. In practical IoT applications, where a huge number of nodes exist, this process becomes almost impossible due to the heterogeneous platforms and protocols involved and the deployment conditions. This paper introduces a flexible and scalable approach that enhances modifiability and programmability through client-server-server-client architecture. It allows changing the behavior of the system after deployment through a lightweight script written with a domain specific language, DoS-IL, and stored in a gateway at the fog layer. An embedded resource browser is used to request and execute the script. The results of analysis for this model and the tools developed along the way are discussed.
