1. A method for communicating within a wireless network of sensors wherein each sensor comprises a transmitter normally operating in a sleep mode, a low power receiver having a memory, a sensing module, a processor normally operating in a sleep mode communicably coupled to the transmitter, the low power receiver and the sensing module, the method comprising the steps of:

  • receiving data via the low power receiver;

    storing the received data in the memory; and

    whenever a wakeup time occurs, putting the transmitter and the processor in an operational mode, obtaining sensory data from the sensing module, processing the sensory data, obtaining the received data from the low power receiver memory, transmitting the processed sensory data and the received data via the transmitter, and putting the transmitter and the processor in the sleep mode.
