摘要： Provided is an apparatus and method of dynamically managing a sensor module on a sensor node in a wireless sensor network. The apparatus includes an update unit, a request unit, and a transmission unit. If a change occurs in sensor data corresponding to each sensor node stored in a sensor information storage server, the update unit receives the sensor data from the sensor information storage server, and transmits the received sensor data to the corresponding sensor node. The request unit requests the sensor data from the sensor information storage server upon receipt of a sensor data request message from the sensor node. The transmission unit receives the requested sensor data from the sensor information storage server and transmits the received sensor data to the sensor node.

The antenna can perform radiation parallel to the earth's surface including other directions. Therefore, it is suitable for an RFID reader which recognizes an RFID tag attached in parallel to the earth's surface. The electrical loop antenna can control impedance matching, resonance frequency, antenna gain, and radiation pattern according to the distance between metal plates, size of the metal plates, thickness of a feeding probe, and how the metal plates are arranged.
