Abstract
A wireless network is provided, that may comprise wireless sensor units organized in chains of wireless sensor units. Each wireless sensor unit may comprise plural sensors and at least a wireless transceiver connected to communicate by wires or wirelessly with the plural sensors. Each chain of wireless sensor units may include a terminal wireless sensor unit and intermediate wireless sensor units, each intermediate wireless sensor unit being configured to relay data along the chain of intermediate wireless sensor units towards the terminal wireless sensor unit. The terminal wireless sensor unit in each chain of wireless sensor units is adapted to communicate wirelessly with at least one backhaul unit of plural backhaul units; and the backhaul units are adapted to communicate with a central computer.

6. A method of collecting data from wireless sensor units arranged in a network, the wireless sensor units being organized in chains of wireless sensor units, each chain of wireless sensor units including a terminal wireless sensor unit and intermediate wireless sensor units, the method comprising the steps of:
-
initiating distribution of control signals to the wireless sensor units; acquiring data with the wireless sensor units by sensing one or more physical parameters; each of the wireless sensor units transmitting the acquired data in response to the control signals along at least one of the plural chains of wireless sensor units towards a corresponding one of the terminal wireless sensor units; each of the terminal wireless sensor units forwarding the acquired data from the wireless sensor units in the corresponding chain to at least one of plural backhaul units; and each of the backhaul units collecting and forwarding the acquired data from the terminal wireless sensor units towards a central computer. - View Dependent Claims (7, 8, 9, 10, 11, 12, 13, 14, 15, 16, 17, 18, 19, 20)
