Abstract:
In this article, a route discovery method based on received power of repeater nodes for sensor networks in a multipath fading environment is studied. When each repeater node received Route Request Message, the message is decided whether accept or not by referring to received power information in Physical Layer. In the destination node, the most optimal route is selected from some route candidates according to the following criteria: received power level, number of hops and sequence number. From the results of computer simulations, it has been clarified that the proposed method has advantages in the route effective time and data distribution ratio comparing with the conventional method even if the route discovery time is lengthened by about 3 seconds.
