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 Distributed Systems, Cyber-Physical Systems (CPS), Wireless Sensors Networks (WSN) scenarios. It was originally designed to improve the flexibility/faithfulness of nodes implementations and mitigate the learning curve compare to existing network simulators.

ESDS is part of a research project. Studies and validation experiments are available online. For more details please visit http://todo.com.

Installation

> pip install esds

To ensure that esds is properly working and installed on your system, you can run the simulation tests with one of the following scripts:

• tests/run.sh
• tests/run.py

Features

• Easy to use
• Small API
• Agent-based: node implementations are located in independant python files
• Wireless interferences detection (i.e no modelization)
• Custom node mobility (by updating the network matrix)
• Nodes plugins (e.g energy consumption)

What ESDS does not implements ?

• Network protocols (e.g IP/TCP/UDP)
• Wireless physical layer models (e.g Friis and Log-Distance models, modulation, RSSI)
• Routing algorithms (e.g Shortest path)
• And much more!

Simulation API

• api.args
• api.send(<int>,<data>,<size>,<dst>)
