Abstract
A multi-hop wireless network monitor method for monitoring a state of a multi-hop wireless network including a plurality of nodes, the method includes: transmitting a packet that stores monitor data indicating a state or performance of a first node and identification information that identifies the first node; rewriting the monitor data stored in the packet with the monitor data detected by a second node and rewriting the identification information stored in the packet with the identification information that identifies the second node in the second node when the monitor data detected by the second node is worse than the monitor data stored in the packet; and specifying a node in the worst state or performance in a propagation route of the packet according to the identification information stored in the packet.
