CLUSTER
The cluster strategy is a peer-to-peer strategy that supports an M-to-N, or cluster-shaped, connection topology. In other words, this enables connecting amorphous clusters of devices within radio range (~100m), where each device can both initiate outgoing connections to M other devices and accept incoming connections from N other devices.
This strategy is more flexible in its topology constraints than the star strategy, but results in lower bandwidth connections. It is good for use cases with smaller payloads that require a more mesh-like experience, such as multiplayer gaming.
