Abstract: Apparatus, methods and logic for vehicles to determine vehicle to vehicle (V2V) safety message transmission rates for transmitting V2V safety messages based on how frequently the vehicles actually need to exchange safety messages, including factors such as vehicle velocities, distances among vehicles, and on how quickly the inter-vehicle distances are closing up. The determined V2V safety message transmission rates are selectively dynamically adjusted in accordance with detected significant changes in one or more of the inter-vehicle distances or inter-vehicle speeds. To avoid needless frequent changes to the transmission rate, statistical modeling techniques including hypothesis testing and sequential change detection are selectively used to more accurately detect significant changes in inter-vehicle distances or inter-vehicle speeds that warrant a change to the message transmission rate.

Abstract: In one embodiment, a machine type communication (MTC) device can receive registration associated with a new device upon the new device registration for a computer network. The MTC device can further determine a machine-to-machine (MTM) service class for the new device based on the registration data with the service class associated with at least one network route for messages destined for the new device. The MTC device can further receive a trigger message destined for the device and route the trigger message according to the network route associated with the determined MTM service class.
