LINK QUALITY BASED ROUTING METHOD IN MULTI-RADIO MOBILE AD-HOC NETWORK

摘要

PURPOSE: A link quality based routing method in a multi-radio mobile ad-hoc network is provided to change a link with interference into a high quality link using SINR(Signal-to-Interference plus Noise Ratio). CONSTITUTION: A route for transmitting data is searched(S201). Link quality of each node is measured within the searched route(S203). A link deterioration is searched based on the measured link quality(S205). The node which searches the link deterioration selects an alternative link. The route is established into a changeable al link(S207).
