ROUTING METHOD AND DEVICE BASED ON RELIABLE LINK ZONE IN AD-HOC NETWORK

摘要

PURPOSE: A routing method based on a link reliability region in an Ad-hoc network and a device thereof are provided to select a routing path based on the link reliability region, thereby enabling more stable data transceiving. CONSTITUTION: SNR(Signal to Noise Ratio) information of a peripheral node is obtained(200). Using the SNR information and reference SNR information, a link reliability cost is calculated and a link reliability region is set(202). Routes through which transmission is possible are searched through an RREQ message(204,206). Using a hop count information and the link reliability cost, a route reliability value is calculated. A route whose route reliability value is minimum is selected(208).
