Mobile node group formation and management
The subject disclosure is directed towards mobile network management by reducing energy consumption and increasing a lifetime of one or more nodes. By determining a beacon listening duration and a beacon listening period in response to an energy budget, each node may minimize or reduce latencies associated with node discovery and/or node group maintenance.

Ue beaconing using rach transmissions for small cells
A method of beacon detection performed by a small cell device includes: exchanging beacon parameters with a user equipment (ue); entering a low power mode after exchanging the beacon parameters with the ue; receiving, from the ue, a beacon in a random access channel (rach) preamble containing the beacon parameters while in the low power mode; entering a high power mode in response to receiving the beacon; and associating with the ue while in the high power mode. The method of beacon detection allows a small cell device to transition from a low power mode to a high power mode in an efficient manner.
