ROUTING METHOD FOR SAVING POWER CONSUMED IN A WIRELESS NETWORK, ESPECIALLY CONCERNED WITH EMBODYING A GRADUAL PROXIMITY TO A ROUTING DESTINATION NODE AND THE OPTIMAL NUMBER OF ROUTING PARTICIPANT NODES
PURPOSE: A routing method for power saving in a wireless network is provided to embody a gradual proximity to a routing destination node and the optimal number of routing participant nodes. CONSTITUTION: An optimal integral number(n) for minimizing the power consumption between a destination node and a source node is established(S41), and n-1 numbers of concentric circles which equally divide the distance(d) between the destination node and the source node into "n" with the destination node in the center are established(S42). Then the present execution node is set as the source node(S43). The present execution node selects candidate nodes on the basis of the distance from the nearest concentric circle towards the destination node and selects a middle node, of which the power consumption is minimal among the candidate nodes(S44). Until the routing between the destination node and the source node ends, the selected middle node is set as the present execution node(S45,S46).
