Modeling and Simulating Concurrent Communications of Distributed Sensing Networks

This paper 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 the local node's behaviors to build up the networks and manage communications. Finally, simulation experiments were carried out on an abstract LoRa wireless network in order to evaluate and validate the accomplishment of the proposed approach for concurrent communications in large-scale distributed sensing networks.
