Abstract
With 5G technologies new platforms for global connectivity of sensing devices are expected, many of them relying on federated sensor networks. Such federation can be done through P2P overlays where proxy nodes, of constrained environments, announce device resources or data. However, P2P resources may end up including similar device resource entries, if these can be announced under different P2P resource umbrellas, posing consistency and efficiency problems. Changes in a device resource (or data) will require the update of multiple P2P resources. To avoid this, a two-layer overlay architecture is used in this article so that P2P resources can include references to P2P anonymous resources, specifically created to avoid duplicate entries. In this article, procedures to keep P2P resources (anonymous or not) updated over time are proposed. Results show that these are effective in avoiding duplicate entries.

A service discovery mechanism like ReDiR can be used to distribute load among RELOAD/CoAP nodes able to provide such service, ensuring scalability.
