    Abstract: A method of extending connectivity of a recipient vehicle may be executed by a non-transitory computer-readable medium. During an ignition off state of the recipient vehicle, the method includes disabling a recipient cellular network access device (NAD) of the recipient vehicle and connecting to a low power communications source. The method includes communicating with a centralized location over the low power communications source. The low power communications source may be a recipient Bluetooth® low energy (BLE) within the recipient vehicle. The method may include connecting to a donor vehicle proximate the recipient vehicle. The donor vehicle includes a donor NAD and a donor BLE, such that the donor NAD of the donor vehicle communicates with the centralized location on behalf of the recipient vehicle.

    Abstract: A location assistance system includes a distress vehicle and multiple assistance vehicles. The distress vehicle broadcasts an emergency signal. The assistance vehicles are operable to receive the emergency signal, determine multiple distances to the distress vehicle, triangulate among the assistance vehicles to generate a spatial map of the distress vehicle relative to the assistance vehicles, determine one or more approximately horizontal lines in the spatial map that include the distress vehicle and at least one horizontally aligned assistance vehicle in response to the distress vehicle and the at least one horizontally aligned assistance vehicle being on a same vertical level in the spatial map, coordinate among the assistance vehicles to determine one or more horizontal sequences along the one or more approximately horizontal lines, and flash the of the assistance vehicles in the one or more horizontal sequences to lead toward the distress vehicle.

    Abstract: A system for managing communication between a vehicle and a broker module includes a telematics unit connected to the vehicle. The telematics unit is configured to carry out wireless data communications according to a publish-subscribe messaging protocol. A command unit is in communication with the telematics unit, the command unit having a processor and tangible, non-transitory memory on which instructions are recorded. The telematics unit is configured to establish a network connection with the broker module. The command unit is adapted to create a dynamic retry delay process for the network connection by varying a connection retry delay time based on a plurality of failure categories and an operation mode of the vehicle. The plurality of failure categories each corresponds to a respective failure in the network connection.
