Abstract: An ad-hoc network can create a private activity-based network for nodes associated with a common activity. A network node of the ad-hoc network can include a first radio for communicating with other network nodes of the ad-hoc network, a second radio for relaying data packets across the ad-hoc network, and a third radio for synchronizing network topology information with a respective network node of the one or more neighboring nodes. Specifically, the first, second, and third radios are different radios that operate concurrently. These three separate radios allow the network node to communicate with other network nodes using the second radio while using the third radio to discover changes to the ad-hoc network topology, and/or to synchronize an updated network topology with other neighboring nodes.
