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.
