摘要： A method of synchronizing wireless devices includes establishing a recurring sequence of frequency channels at which the wireless devices are to communicate. The frequency channels are divided into a plurality of groups. Synchronization information is transmitted at a respective first frequency channel in each of the groups of frequency channels during a first sampling time period. One of the groups of frequency channels is selected. A wireless device is used to sample each of the frequency channels in the selected group during the first sampling time period. Non-synchronization information is transmitted after the first sampling time period. Synchronization information is transmitted at a next respective frequency channel in each of the groups of frequency channels during a next sampling time period. The next sampling time period occurs after the transmitting of the non-synchronization information.

A sleep mode is periodically awoken from to listen for the wakeup tones. The pattern of wakeup tones is received during the listening. It is decided whether to listen for at least one second tone. The deciding is dependent upon the received pattern of wakeup tones.

摘要： A data encryption method includes providing a sender node having information to transmit. The information is divided into a sequence of frames. A respective one of a plurality of frame numbers is assigned to each of the frames. At least one nonce and at least one security key are used to perform block cipher encryption and produce within the sender node a respective block cipher encryption output for each of the frames. The information is converted from a sequence of plaintext frames to a sequence of ciphertext frames by use of the block cipher encryption outputs produced within the sender node. The converting is performed within the sender node and after the block cipher encryption outputs have been produced within the sender node. A receiver node is used to ascertain the frame numbers. The at least one nonce is transmitted from the sender node to the receiver node. The at least one nonce and the at least one security key are used to perform block cipher encryption and produce within the receiver node a respective block cipher encryption output for each of the frames. The ciphertext frames are transmitted from the sender node to the receiver node. The ciphertext frames are transmitted after the block cipher encryption outputs have been produced within the receiver node. The transmitted ciphertext is converted back into the plaintext frames by use of the block cipher encryption outputs produced within the receiver node. The converting is performed within the receiver node and after the block cipher encryption outputs have been produced within the receiver node.

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.
