ROUTING SYSTEM FOR SELECTING ACCESS NODE BY USING GEOGRAPHIC INFORMATION AND METHOD FOR SELECTING ACCESS NODE

摘要

A routing system for selecting an access node by using geographic information, according to the present invention, comprises: a geographic information saving unit for saving geographic information corresponding to geographic information IDs, which are assigned to each access node; a measurement unit for measuring a possible packet transmission distance of each of the access nodes on the basis of the geographic information; and a node selection unit for selecting, as the next transmission node, the access node located at the shortest distance, from among a plurality of access nodes within the possible packet transmission distance, wherein the node selection unit selects, as the next transmission node, the access node located on a packet path having no obstacles and at the shortest distance, from among the plurality of access nodes within the possible packet transmission distance, when obstacles are present between the access node at the shortest distance and the packet path.
