METHOD, APPARATUS, AND COMPUTER PROGRAM PRODUCT FOR LOW POWER DATA DELIVERY

摘要

An example embodiment enhances power savings in a wireless network, where each wireless device has a hop count value indicating how many hops away is one or more central wireless devices. A device determines that it has information to deliver to the one or more central devices. It selects a device of the one or more other wireless devices, the selected device having a smaller hop count value, than the hop count value of the device. It enters a sleep mode based on a known repetition interval of wireless device discovery messages received from the selected device. The device awakes from the sleep mode based on the known repetition interval of wireless device discovery messages of the selected device. It then creates a connection with the selected device and transmitting to the selected device the information for delivery to the one or more central devices via the connection.

主权项

1. A method, comprising:
receiving, by an apparatus, wireless device discovery messages from one or more other wireless devices in a wireless network, each received wireless discovery message including a received hop count value indicating how many hops away from one or more central wireless devices, a respective one of the one or more other wireless devices is that sent the received wireless discovery message; memorizing, by the apparatus, a smallest hop count value indicated in the received wireless device discovery messages; and transmitting, by the apparatus, wireless device discovery messages including a transmitted hop count value of the apparatus, which is one greater than the smallest hop count value, indicating how many hops away the apparatus is from one or more central wireless devices.
