US 8,509,764 B2 · Method and system for broadcast message rate adaptation in mobile systems

Abstract

A method and system for setting transmission rate of messages transmitted and received by a mobile unit. The method and system include monitoring the speed of the mobile unit; and adjusting the transmission rate based on the speed of the mobile unit. Prevailing conditions may also be determined and the transmission rate may be further adjusted based on the prevailing conditions. The prevailing conditions may be determined based on at least one of states of one or more sensors local to the mobile unit and information provided from an external source over a communication system. The prevailing conditions may include at least one of slick pavement, limited visibility, road construction, object in roadway, accident, dense traffic, and anomalous driving behavior.

A method for setting broadcast rate of messages broadcast and received by a mobile unit, the method comprising:

broadcasting a message at a message broadcast rate over a wireless communication channel;
receiving current speed of the mobile unit, from the mobile unit;
and
adjusting the message broadcast rate based on the received current speed of the mobile unit, wherein the message broadcast rate is adjusted such that the message broadcast rate is continuously decreased as the speed of the mobile unit is reduced, and the message broadcast rate is continuously and linearly increased within minimum and maximum range as the speed of the mobile unit is increased.
