摘要:
A method for establishing and maintaining the network and a corresponding ad-hoc moving-device to moving-device network having a plurality of moving-devices grouped into a Local Peer Group (LPG) is disclosed. A group header node (GH) is selected from the plurality of moving wireless devices in the LPG. The GH controls and manages the LPG by broadcasting a plurality of control messages, including a heartbeat message at a fixed interval. The LPG also includes at least one group node (GN). The at least one GN can communicate with the GH via a network link created between the at least one GN and the GH. The GNs join the LPG via the GH. If there is more then one GH in an LPG, header resolution occurs to select only one GH.
