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:
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.

A method for providing electronic communications between wireless nodes includes wirelessly transmitting data from a transmitting one of the nodes to a plurality of receiving ones of the nodes. A respective first acknowledgment tone is wirelessly transmitted from each of the receiving nodes to the transmitting node and to each other one of the receiving nodes. Each first acknowledgment tone is transmitted in response to the respective receiving node receiving the transmitted data. Each of the first acknowledgment tones is transmitted in a respective, unique time slot. At least one second acknowledgment tone is wirelessly transmitted from at least one of the nodes to each other one of the nodes. The second acknowledgment tone is transmitted dependent upon whether a group of received first acknowledgment tones matches a group of expected-to-be-received first acknowledgment tones.

A method of acknowledged communication in a network includes transmitting a message to at least one node of the network, wherein the message is transmitted in each of a plurality of broadcast rounds that overlap one another according to a predetermined broadcast schedule, receiving the message by the at least one node, and transmitting an acknowledgement of the message from the at least one node, wherein the acknowledgement is transmitted in each of a plurality of collection rounds that overlap one another according to a predetermined collection schedule.

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:
A system and method for operating a wireless network provides for sending a wakeup tone, periodically waking up from a sleep mode to listen for the wakeup tone, upon receiving the wakeup tone, listening for at least one second tone, the at least one second tone being one of (i) a tone in a frequency different from the wakeup tone and (ii) a pattern of tones including at least one frequency different from the wakeup tone, and upon receiving the at least one second tone, performing an action based on the at least one second tone.
