1. A method of displaying topology information of a sensor network having a plurality of sensor nodes, comprising:
- receiving node information collected and extracted from a plurality of sensor nodes;
comparing the received node information with previously stored node information;
computing, when the received node information is unequal to the stored node information, visualization information regarding a sensor node of said plurality of sensor nodes whose information is included in the received node information and is not present in the previously stored node information;
providing an output for display of sensor nodes on concentric circles using the visualization information; and
displaying the plurality of sensor nodes on concentric circles using the visualization information on a display, wherein the displaying comprises arranging a cluster node at a center of the concentric circles and arranging an originating node and a parent node of the originating node respectively on an outer one and an inner one of two consecutive concentric circles.
