    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.

    摘要翻译： 描述了网络节点控制，其包括节点唤醒调度，其减少节点级的能量消耗，并减少通过网络的信息传递的延迟。 节点唤醒调度包括在一个级别中组合两个唤醒的交叉梯形图案。 节点唤醒调度还包括交叉梯形图的自适应版本，其随时间改变交叉梯形图的唤醒模式以提供均匀的能量节省。 网络节点控制还包括使用多个树通过网络传输信息。 该多父节点分配为网络中的每个节点分配具有不同唤醒时间表的多个父节点。 这种多父分配减少了通过网络传输信息的延迟，并且还增加了节点的能量效率。

    摘要： A wireless networking method includes providing a plurality of different sets of wireless links and a plurality of wireless nodes. The nodes are in mutual bidirectional wireless communication via the wireless links. Each of the links enables the communication between a respective pair of the nodes. Information is transmitted to a selected one of the nodes from each of other ones of the nodes via a first of the sets of the wireless links. The step of transmitting information to the selected one of the nodes from each of other ones of the nodes is repeated via each of other ones of the sets of the wireless links, respectively.

    摘要： A wind turbine condition monitoring system and method are disclosed where the wind turbines include a tower, a gearbox coupled to the tower, and turbine blades coupled to the gearbox. The monitoring system includes blade sensors coupled to the blades, a hub node coupled to the gearbox and a controller. The controller is in communication with the hub node and blade sensors, and determines blade positions based on blade sensor readings. The blade sensors and hub node can include multi-axis accelerometers. The controller can wirelessly communicate with the blade sensors directly or through the hub node. Using position information, shadowing areas with obstructed communication can be avoided, node separation can be accounted for to reduce power requirements and/or interference from multiple transmitters can be avoided during node communications.

    摘要： A method of wirelessly transmitting alarm signals includes wirelessly transmitting an alarm signal from a transmitting station. It is determined whether an acknowledgement signal wirelessly transmitted from an access point in response to the access point receiving the alarm signal has been received by the transmitting station. A relaying station is woken up and kept awake during a plurality of periodic time intervals for overhearing transmissions from the transmitting station. If it is determined that an acknowledgement signal from the access point has not been received by the transmitting station, then the alarm signal is wirelessly re-transmitting from the transmitting station during at least one of the time intervals in which the relaying station is awake. The alarm signal is received at the relaying station. The alarm signal is transmitted from the relaying station to the access point.
