Geo-Replicator® Replication in Ad-Hoc Mesh Networks

In locally synchronising data between mobile assets, ad-hoc mesh networks involving multiple point-to-point links between nodes become necessary to enable timely propagation of changes to data.

The characteristics of, and requirements for replication over, such networks will be:

• Short-range links, not involving connectivity outside of a local group of nodes
• Low bandwidth, potentially unreliable links, whose up-time cannot be guaranteed and are likely to come and go, especially in military scenarios
• Links potentially intermittent (hence particular nodes may prove uncontactable for arbitrary periods), and nodes themselves may cease to be operational for periods of time, potentially forever
• Some links may have different bandwidth and reliability/intermittence characteristics to others (e.g. – consider a fleet of ships with command ships and more mobile pickets, or aerial assets which may roam significant distances from the ‘hub’ of the fleet).
