摘要： Network node control is described that includes node wakeup scheduling that reduces the energy consumption of levels of nodes and reduces the delay of information transfer through the network. The node wakeup scheduling includes a crossed ladder pattern that combines two wakeups in one level. The node wakeup scheduling also includes an adaptive version of the crossed ladder pattern that changes the wakeup patterns of the crossed ladder over time to provide uniform energy savings. The network node control also includes the use of multiple trees to transfer information through a network. This multi-parent node assignment assigns multiple parents with different wakeup schedules to each node in the network. This multi-parent assignment reduces the delay in transmission of information through the network and also increases energy efficiency in the nodes.

摘要： A data communication method includes providing a sender node having a data packet of information. The data packet includes at least one first field and a second field. The second field has content that is dependent upon actual content of the at least one first field. The content of the second field of the data packet is transmitted from the sender node to a receiver node. The receiver node is used to predict the actual content of the first field of the data packet. The receiver node is used to calculate the content of the second field of the data packet based upon the predicted content of the first field. The predicted content of the first field is confirmed to be equivalent to the actual content of the first field. The confirming step includes comparing the calculated content of the second field to the transmitted content of the second field.

摘要： In a wireless transmission system, a transmitter sends a plurality of data packets to a receiver. The transmitter identifies channel quality indicators corresponding to properties of a communication channel between the transmitter and the receiver. During operation, the transmitter adjusts one or more parameters that affect the Quality of Service (QoS) of data transmission between the transmitter and receiver to enable data transmission at different quality levels over a range of channel quality levels. In one embodiment, the transmitter sends data packets corresponding to video from a camera to the receiver.

摘要： For each first tracker in a first subset there exists a respective second tracker in a second subset such that a distance between the first tracker and the second tracker is shorter than each distance between the second tracker and each of the other first trackers in the subset by more than a threshold distance. In a first time slot, data is wirelessly transmitted using a same first frequency from each of the first trackers in the subset of the first trackers to the respective second tracker in the subset of the second trackers. In a subsequent time slot, the data is wirelessly transmitted from each of the second trackers in the subset of the second trackers to a final destination data collector.

摘要： A method of wireless communication includes providing a matrix of trackers. The matrix includes rows and columns of trackers. A number of rows and a number of columns in the matrix is determined. If the number of rows is substantially greater than the number of columns, then vertical sweeping is performed including passing data along each of the columns of trackers to an end tracker in each column. If the number of rows is substantially less than the number of columns, then horizontal sweeping is performed including passing data along each of the rows of trackers to an end tracker in each row. If the number of rows is substantially equal to the number of columns, then diagonal sweeping is performed including passing data diagonally across each of the rows and columns of trackers to an end tracker in each row and each column. The data is passed along the end trackers to a final destination data collector.

摘要： A method of operating wireless devices includes providing a plurality of sender nodes each having a respective message to wirelessly send to a receiver node. A probability distribution is assigned to a plurality of frequency channels such that a respective probability of selection is assigned to each frequency channel. At least two of the probabilities of selection are unequal. A respective frequency channel is probabilistically selected for each of the sender nodes according to the probability distribution. The messages are wirelessly sent from the sender nodes to the receiver node in the selected frequency channels. The receiver node is used to sample a first one of the frequency channels and a second one of the frequency channels. The second frequency channel has a higher respective probability of selection than the first frequency channel. If the receiver node sensed a signal in both the first frequency channel and the second frequency channel during the sampling, the receiver node is tuned to the first frequency channel and receives a remainder of the message on the first frequency channel.
