Abstract: A multi-path routing method is provided a multi-path routing method for selecting appropriate multiple paths when information sensed from a source node is transmitted to a sink node in wireless sensor networks. The source node for transmitting the sensed information first transmits a Hello message to the sink node to identify the existence and position of the sink node. The sink node receives the Hello message and then re-transmits the Hello message with respect to all the received Hello messages. Respective middle nodes accumulate distances between the middle nodes while the Hello message is transmitted to the source node through a reverse path of the Hello message, and all the middle nodes maintain a real distance from the sink node. The source node receiving all the Hello messages can rout a plurality of appropriate paths through Hop-by-hop to the sink node by providing respective weights to an energy remaining amount, an appropriate transmission radius and a real distance from the sink node. Accordingly, priorities can be provided to lifetime of the source node, average energy consumption and the shortest path by adjusting the respective weights when routing the plurality of paths. In addition, appropriate paths can be routed considering the transmission success rate of a path, and a load balancing effect can be obtained using path cost.

Abstract: A blind rate detection method in an asynchronous mobile communication system comprises: restoring data when a path selection (PS) value at a last bit's possible position satisfies a PS condition; determining whether a SER satisfies a SER condition when no error occurs in a CRC; determining whether to update a minimum value of PS values when the SER satisfies the SER condition; setting a PS value of the last bit's possible position as the minimum value of the PS values and the last bit's possible position as a last detection position when updating the minimum value; and repeating the above steps until the last bit's possible position reaches a maximum value, and outputting the last detection position when the last bit's possible position becomes the maximum value.
