METHOD FOR SELECTING CONTENT FORWARDING NODE IN VEHICLE AD-HOC NETWORK ON THE BASIS OF SERVICE TYPE
A method for selecting a content forwarding node in a vehicle ad-hoc network on the basis of service type, comprising the following steps: calculating a bandwidth occupation proportion factor according to the type of requested content information and a bandwidth occupation situation of a neighboring vehicle which can perform forwarding in a one-hop transmission range; defining a virtual arrival time of a candidate forwarding vehicle to an initial request vehicle according to the distance between the neighboring vehicle and the initial request vehicle and a driving speed of the neighboring vehicle; calculating a forwarding node impact factor according to the bandwidth occupation proportion factor and the virtual arrival time; and selecting a forwarding node according to the forwarding node impact factor.
Method for performing uplink transmission in wireless communication system, and device therefor
The present specification relates to a method for performing uplink transmission in a wireless communication system. More specifically, a method performed by a terminal comprises the steps of: transmitting, to a base station, a plurality of PRACH preambles related to a plurality of transmission units indicating a physical layer resource set; receiving, from the base station, a plurality of random access responses (RARs) corresponding to the plurality of PRACH preambles, wherein each of the plurality of RARs comprises a temporary cell (TC)-RNTI; and transmitting, to the base station, a plurality of uplink signals on the basis of the plurality of RARs, wherein the uplink signals comprise information on overlapped TC-RNTIs.
Systems and methods for providing robust connectivity to vehicles
Systems and methods are provided to manage, control, and configure connectivity for vehicles or other devices. Data in different formats, which is received from different connectivity providers, is converted into a unified data format and stored in a data store. The unified data format allows analytics to be performed across the converted data. In some embodiments, a connectivity type of a plurality of connectivity types associated with a vehicle is controlled based on a current lifecycle stage of the vehicle. In some embodiments, a first data connection between a device and a first connectivity provider is utilized. Based on an identified change in location of the device and information associated with a second data connection between the device and a second connectivity provider, a switch to the second data connection is facilitated based on a determination that that the second data connection has more optimal characteristics.
Data Processing System Communicating with a Map Data Processing System to Generate a Display of One or More Segments of One or More Vehicle Routes
Systems and methods are disclosed for generating a display of a navigation map. The system may comprise a historical data source device having, for example, a historical data source computer and a database storing historical data associated with one or more of vehicle accident data, traffic data, vehicle volume data, vehicle density data, road characteristic data, or weather data. The system may comprise a map data processing device having a map data processing computer and memory storing computer-executable instructions that, when executed by the map data processing computer, cause the map data processing device to, for example, determine, based on a location determining device, a location of a vehicle. The map data processing system may determine one or more historical factors based on the location of the vehicle. The map data processing system may receive, from the historical data source device and for the location, historical data associated with the one or more historical factors. Based on the location of the vehicle, one or more real time factors and real time data associated with the one or more real time factors may be calculated. The map data processing system may calculate, using the one or more historical factors and the one or more real time factors, a navigation score for each segment of a route from the location to a destination location. The map data processing system may determine one or more colors for each navigation score and/or generate a display of a navigation map comprising the one or more colors.
