Abstract [en]

NOVELTY - The method involves determining the beacon transmit power at which a radio node transmits the beacons, based on the estimate of network dynamics. USE - For transmitting beacon messages between mobile radio nodes such as cellular phone, laptop computer and personal digital assistant (PDA) in ad-hoc or multihop networks. ADVANTAGE - Enables increasing the accuracy of topology map, and maintaining connections efficiently when topology changes, also enables reducing the power consumption of radio nodes, thereby improving the durability of battery of mobile radio nodes. DETAILED DESCRIPTION - INDEPENDENT CLAIMS are also included for the following: (1) radio node; (2) computer program product comprising computer storage medium storing beacon message transmission program; and (3) system of radio nodes. DESCRIPTION OF DRAWING(S) - The figure shows a flowchart explaining the beacon message transmission process.
