ESDS: An Extensible Simulator For Distributed Systems and Cyber-Physical Systems

What is ESDS ? It is a short learning curve and coarse-grain network simulator. It contains the essential building blocks for the simulation of Cyber-Physical Systems (CPS) and Wireless Sensors Networks (WSN) scenarios. It was originally designed to improve node implementation flexibility/faithfulness and mitigate the learning curve compare to existing network simulators.

What ESDS does not implements?

• Network protocols (such as IP/TCP/UDP)
• Wireless physical layer models
• Routing algorithms
• And much more!

Features:

• The implementation of node behavior can be any python file that you have wrote
• Wireless interferences detection (not modelization)
• Simulation can be interrupted at constant intervals to perform custom actions (such as implement nodes mobility)

Current API:

• api.args
• api.send(<int>,<data>,<size>,<dst>)
• api.sendt(<int>,<data>,<size>,<dst>,<t>)
• api.receive(<int>)
• api.receivet(<int>,<t>)
• api.wait(<t>)
• api.wait_end()
• api.log(<message>)
• api.read(<register>)
• api.turn_on()
• api.turn_off()
• More details in example/sender.py
