Title:
RETRIEVAL AND DISPLAY SYSTEM FOR NODE POSITION ON RADIO COMMUNICATION MULTI-HOP NETWORK
Document Type and Number:
Japanese Patent JP2007306280
Kind Code:
A
Abstract:
To provide a method of visually displaying the position relation (predicted direction) between a current position and the installation position (place) of a target node and how close to each other they are so as to find the target node.
Link information used for the radio multi-hop network is used to gather the numbers of Hops (the numbers of relay nodes in communication) of respective paths between a terminal device for retrieval that a user carries (a mobile PC) and the target node, and how close to the target node the terminal device is displayed with values of the gathered numbers of Hops. The terminal device is closer as the number of Hops is smaller, and farther as the number of Hops is larger.
