TRACKING OF AND COMMUNICATION WITH MOBILE TERMINALS USING A BATTERY-POWERED WIRELESS NETWORK INFRASTRUCTURE. |
摘要 |
There is provided a method of reducing energy consumption of tag readers in a wireless network, the method comprising: (a) turning a transmitter and a receiver of the tag reader to a power-off state; b) powering-on the transmitter of the tag reader for a limited transmission time frame; c) during the transmission time frame, transmitting a beacon message comprising an identifier of the tag reader, channel characteristics of the tag reader and a powering-on schedule of the receiver of the tag reader, for allowing tags in the network to communicate with the tag reader, where the tags are almost continuously in a power-on state; d) powering-on the receiver of the tag reader during a limited reception time frame in accordance with the schedule, for enabling the receiver to receive messages transmitted by the tags in the network if required; e) repeating steps a) to d) periodically. There is further provided a battery-powered tag reader which reduces energy consumption. There is further provided a battery-powered wireless network with an energy management for tag reader. There is further provided a method of increasing probability of detection of rapidly moving clusters of mobile nodes in a wireless network. |
