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 node implementation flexibility/faithfulness and mitigate the learning curve compare to existing network simulators.

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

Installation

> pip install esds

Features

Easy to use
Small API
Agent-based: node implementations are 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!
