Abstract: <P>PROBLEM TO BE SOLVED: To notify an entire ad hoc network of a numerical value that exceeds a maximum value of the number of hops between nodes in the ad hoc network without fail, so as to utilize the numerical value from any communication apparatus.  <P>SOLUTION: A maximum MAC address, a hot count and a maximum hop count are notified to a frame like a beacon of wireless communication, for example, to be communicated with each other between nodes, and all the nodes measure the number of hops from the maximum MAC address and mutually notify the maximum hop count so as to utilize them in all the nodes. When H(x, y) is defined as a hop count of (x) and (y) and a hop count from a node having the maximum MAC address to the most distant node is defined as hmax using αG (here, α indicates a symbol of "existing"), βa and βb (here, β indicates a symbol of "to any arbitrary...") and γG (here, γ indicates a symbol of "belonging to"), the inequality of H(a, b)≤H(a, max)+H(max, b)≤2*hmax is established, so that the number of hops between arbitrary two nodes in that group can be suppressed with 2*hmax.  <P>COPYRIGHT: (C)2006,JPO&NCIPI
