Safety message generation rate adaptation in LTE-based vehicular networks

摘要

Long Term Evolution (LTE) appears to be a practical and economical alternative to IEEE 802.11p for the rapid deployment of vehicular safety applications. Vehicles periodically broadcast messages, aka beacons, that contain their location and speed. Ideally, vehicles should have accurate knowledge of the locations of surrounding vehicles, and, if possible, have a same level of precision regardless of their speed.
