METHOD AND APPARATUS FOR PROVIDING COMMUNICATION IN GROUND SENSOR NETWORK

摘要

PURPOSE: A method and apparatus for providing communication in a ground sensor network are provided to reduce environmental influence using a magnetic field induction method. CONSTITUTION: A collector(100) is fixed or moved. The collector transfers a polling message to a sensor node(200). The polling message uses magnetic field induction. The sensor node charges electricity while receiving the polling message. The sensor node is able to attempt a transmission at transmission probability p based on an aloha protocol.
