Lightweight node synchronization protocol for ad-hoc peer-to-peer networking of on-body combat systems

Embodiments may relate to synchronizing nodes in a peer-to-peer network. A method comprises listening for a first multicast beacon during a duration of a discovery interval. The discovery interval comprises time intervals configured for a plurality of nodes in a squad. The method further comprises, in response to receiving the first multicast beacon during the duration of the discovery interval, transmitting a unicast synchronization request to a transmitter of the first multicast beacon. The unicast synchronization request comprises a node list. The method further comprises comparing the node list in the unicast synchronization request to a stored node list comprising node information for the squad, determining node information differences based on the comparison, and in response to determining the one or more node information differences, requesting node information from nodes associated with the node information differences and transmitting a second multicast beacon comprising the one or more node information differences.
