Abstract—This article describes research on modeling and simulating concurrent communications of distributed wireless sensor networks for improving available network capacity. The workflow with software tools was proposed that allows producing automatically Occam-Pi code to feature a concurrency model inspired by Communicating Sequential Processes (CSP) paradigm. Wireless networks are presented based on a graph abstraction model for simulating the complex behaviors of systems. Concurrent communications of distributed sensing networks are handled by the well-known message-passing model used to program parallel and distributed applications. Parallel and distributed algorithms were employed to describe local node’s behaviors to build up the networks and manage communications of distributed sensing systems in environmental monitoring. Finally, code synthesis to port on executing hardware was carried out on an actual LoRa wireless network in order to assess the feasibility and usefulness of our approach for concurrent communication.
