    摘要: The traffic information providing device receives traffic information corresponding to a bus stop or a platform at which the traffic information providing device is positioned from a management server for collecting traffic information from at least one public transportation means, and broadcasts the received traffic information to the traffic information receiving device that is provided within a predetermined distance from the traffic information providing device by using the ZigBee or wireless sensor network that is a wireless personal area network (WPAN). The traffic information receiving device receives traffic information from the traffic information providing device by using the ZigBee or wireless sensor network, filters the same according to a filtering condition input by the user, and outputs traffic information desired by the user.

    摘要: Provided are a separable device for controlling a node and a sensor network node. The separable node-control device includes: a second interface connecting a power line and a data signal line with the outside; and a power supply for supplying power to the second interface and a sensor unit, wherein the power supply and the second interface are controlled by an external control device combined with the second interface and the controller are driven by power supplied from the external device. According to the separable node-control device and the sensor network node, the node-control device is separated from the sensor network node so that the function of the sensor network node can be readily changed according to need.
