摘要： A method for receiving and storing a packet of symbols. The method decodes the packet of symbols using a first decoding algorithm, and if the first decoding algorithm fails to correctly decode the packet of symbols, then the method decodes the packet of symbols using a second decoding algorithm. If the second decoding algorithm fails to decode the packet of symbols, then a third decoding algorithm is used. The third decoding algorithm can be sub-packet decoding, where a first sub-packet is part of the packet of symbols. If the first sub-packet is decoded successfully, then the method generates a channel estimate using the properly decoded information, and then uses that channel estimate to decode a subsequent sub-packet using the channel estimate, where the second sub-packet is a set of symbols that are a portion of the packet of symbols.

摘要： A self-contained vehicular traffic travel time information system for a vehicle in an inter-vehicle ad-hoc network includes an on-board vehicular broadcasting unit for communicating with other vehicles within the inter-vehicle ad hoc network. A positioning device identifies the vehicle's position throughout a course of travel. An on-board vehicle processing unit stores road segments throughout the vehicle path of travel. The on-board vehicle processing unit determines a starting position and an ending position for each respective road segment. A length of time for traveling through each respective road segment is determined. A memory storage device stores the segmented road portions and the time of travel associated with each respective road segment. The on-board vehicular broadcasting unit disseminates the determined travel times of recently traveled road segments via a broadcast message to other vehicles within the inter-vehicle ad hoc network.

摘要： A method for determining which of a plurality of data connectivity pipes will be used to transmit data for one or more applications operating on a vehicle. The method identifies which of the applications are active at a particular point in time and identifies a number of available configurations based on the number of applications that are active and the number of the data pipes that are available to transmit the data for the application. The method identifies a plurality of performance metrics for each configuration and determines an optimal performance value for each performance metric from all of the configurations. The method then determines an overall utility function for each configuration that is based on its performance metrics and the optimal performance value and selects a data pipe for each application that is active based on a maximum overall utility function from each application's available overall utility functions.

摘要： A method is provided for delivering data messages in an inter-vehicle ad hoc network. The inter-vehicle ad hoc network utilizes a multi-hop routing protocol for storing, carrying forward and distributing a data message to various vehicles traveling along the road. The method includes determining a first cluster consisting of a group of vehicles proximate to one another traversing along a road in a first direction. A determination is made as to which vehicles within the first cluster are trailer vehicles for re-broadcasting messages based on vehicle position within the first cluster. An event is detected in a travel path of the first cluster by one of the vehicles in the first cluster. The event is reported to other vehicles in the cluster. At least one vehicle in a second cluster moving in an opposite direction to the first cluster is detected. The data message is broadcast from the determined trailer vehicles to the second cluster.

摘要： A system and method for providing geo-service advertising messages using a wireless vehicle-to-infrastructure (V2X) communications network. Messages are transmitted from a business that identify the type of business, the name of the business and the location of the business, which are received by vehicles traveling within a certain distance of the business. The messages can be rebroadcast by the vehicles receiving the messages from the business to other vehicles either in a multi-hop information routing manner or in a delay-tolerant network information dissemination fashion so that the messages are sent to a wider area, but within a predetermined geographic area and with a predetermined time. If a particular user of the system wishes to learn about a particular business or type of business, he can activate the system so that the messages being sent between the vehicles and from the businesses can be displayed to the user for his use.

摘要： A system and method for providing a protocol to maintain a persistent warning message in a region of interest. The protocol begins its operation when a hazardous condition is detected by a vehicle. The detecting vehicle uses a multi-hop geocast broadcasting process to transmit a warning message to other vehicles in the region of interest. When the vehicles in the region of interest receive the warning message, they are prevented from re-broadcasting the message for a first predetermined period of time. After the first predetermined period of time has expired, a contentious timing process is used to determine which of those vehicles will re-broadcast the message to other vehicles entering the region of interest. This process of re-broadcasting continues until a second predetermined period of time expires at which time the message is not re-broadcast.
