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

摘要

PROBLEM TO BE SOLVED: To reduce the load applied to a network, in an ad hoc network path construction system.SOLUTION: A node receives a request packet containing a data describing the MAC address and positional information of a center node, from the center node, determines presence/absence of a request transmission destination node becoming the transmission destination of the request packet, and when a determination is made that there is a request transmission destination node, describes the MAC address and positional information of the node itself additionally to the data of the received request packet, transmits the described request packet to the request transmission destination node, and when a determination is made that there is not a request transmission destination node, determines that the node itself is a termination node, generates a reply packet containing data describing all MAC addresses and all positional information described in the data of the received request packet, and transmits the reply packet to a request transmission source node, i.e., the transmission source of the received request packet.SELECTED DRAWING: Figure 4
