Abstract
A method and system for determining a size of a local peer group (LPG) network in a dynamic roadway (mobile) environment is provided. In one embodiment, the method comprises measuring a roundtrip time between a first node and a second node, and utilizing the measured roundtrip time to select the size of the local peer group network from a lookup table. In another embodiment, the method comprises determining when the roundtrip time exceeds a time interval of the heartbeat signal, and when the roundtrip time exceeds the time interval of the heartbeat signal adjusting the size of the local peer group network.
