Abstract:
The growing demand for sensor devices, key elements of cyber-physical systems and the Internet of Things, requires fast development of new applications. However, the specification and implementation of such systems is a complicated task, especially because of the lack of support for code reuse and for defining the program execution flow. Service orchestration is a technique that has been widely adopted for developing applications for the cloud. In this paper we propose a similar technique for developing applications for Wireless Sensor Networks (WSN). To this end, we propose a development model based on reusable software components for WSN applications. For the components orchestration, which defines the application execution flow, we propose a domain-specific language, called SLEDS-SD (State Machine-based Language for Sensor Devices). In its current implementation, SLEDS-SD generates nesC code, which can be installed in TinyOS-based devices. The evaluation involved the development o
f three cluster-based WSN models. The efficiency of the proposal was evaluated by determining the amount of code reuse, while its efficacy was evaluated by the generated code correctness. For that, we compare the generated programs behavior with those reported in previous studies.
