AD HOC NETWORK ROUTE CONSTRUCTION SYSTEM, NODE, CENTER NODE, AND AD HOC NETWORK ROUTE CONSTRUCTION METHOD

摘要

To newly construct a route of an ad hoc network in real time and in a short time.SOLUTION: A center node generates a request packet including a data part describing a MAC address of and position information on the center node, and a header part describing a positive integer value as time to live, and transmits the request packet to one or more next hop nodes located in an area where the nodes can communicate with the center node. Each of the next hop nodes receives the request packet, when determining that a value of the time to live described in the header part of the request packet is 0, generates a reply packet including a data part describing all of MAC addresses and all pieces of position information described in the data part of the received request packet, and transmits the reply packet to a request transmission source node that is a transmission source of the received request packet.SELECTED DRAWING: Figure 4
