| 20090073880 | SYSTEM AND METHOD FOR CONTROLLING CONGESTION IN A DEDICATED SHORT RANGE COMMUNICATION SYSTEM - A system and method is disclosed for controlling congestion in communications between an RSE and multiple OBEs in a DSRC system. In certain embodiments, a system and method for controlling congestion in communications between an RSE and multiple OBEs includes determining a priority level for each of multiple OBEs with respect to reserving a channel between each OBE and an RSE. Based on this determination, each OBE is assigned a waiting period based on their respective priority levels. The OBEs then send requests to reserve a channel to the RSE after waiting the assigned waiting periods. | 03-19-2009 |
