Java Gossip Protocol Simulator API

An experimental Java 17 API to enable simulating the dissemination of data across nodes (Hosts) in a network using the Gossip epidemic protocol.

The API enables running the simulation using a single computer. Every node is represented by a Plain Old Java Object GossipNode. Therefore, since this is a simulation API, there is no actual network communication, not even in localhost.

1. Examples

The figure below shows an example of the output for a simulation cycle, where nodes send a message to their neighbors. An infected node 🐞 is that one which has already received a message, otherwise it’s a non-infected node 💚.

A complete example is available here.
