Location-based route management for vehicle-to-everything relay communications

Abstract

The subject matter described herein is directed towards a technology that increases the reliability of transmitting information, by propagating received information in a location-controlled and route managed multiple-stage chain communication in a wireless communication system. A transmitting device transmits a broadcast or group-cast communication message in conjunction with transmitter and receiver location data (e.g., absolute or quantized coordinates). An intermediate device that receives the communication message determines a communication path based on the received location data, and determines whether the intermediate device is within the communication path based on its own location. Only intermediate devices that are within the communications path, and that otherwise satisfy retransmission policy, perform the retransmission. In one aspect, the communication path that is determined can be shaped based on one or more other factors, such as whether the communication message is highly reliable data traffic.
