摘要： A method of reducing an energy consumption of a wireless network, the method including periodically entering a sleep mode by a receiver node, broadcasting a signal simultaneously across a wide band frequency range, upon waking up from the sleep mode, listening by the receiver node to only a first narrow part of the wide band frequency range, the receiver node subsequently either returning to sleep if a signal strength of the broadcasted signal is less than a predefined signal strength threshold, or staying awake for an additional period of time if the signal strength of the broadcasted signal is greater than the predefined signal strength threshold.

摘要： Embodiments of a link assessment and frequency monitoring system for use in wireless sensor networks are described. In one embodiment, each frequency utilized by links coupling two or more nodes in the network is sampled to determine a noise measure for each frequency. A correlation measure based on the distance between the noise measures for each pair of frequencies is determined. The frequencies are then clustered into a number of groups of frequencies based on the correlation measure between each pair of frequencies, such that the number of groups is less than the total number of frequencies. A representative frequency for each group of frequencies is selected, and a link quality assessment for each pair of nodes in the network is performed for the representative frequency of each group of frequencies.
