METHOD AND APPARATUS TRANSMITTING DATA BASED ON LINK QUALITY IN WIRELESS NETWORK

摘要

PURPOSE: A link quality based data transmission method in a wireless network and a device thereof are provided to transmit data by selecting a transmission path including the link quality which is over a threshold value. CONSTITUTION: A link quality measuring unit(613) receives a transmitted control packet. The link quality measuring unit measures the link quality for a link of a node transmitting the control packet. A path cost calculation unit(614) calculates the path costs based on the measured link quality. A flag setting unit(615) sets a flag by comparing a threshold value with the calculated path costs. A storage unit(616) stores a routing table including the set flag.
