Abstract:
A method for transferring data in a method for transferring data signals by a data communication system comprising at least one node, the method comprises: transmitting a wakeup message when a source node receives a probe packet from at least one of other communication nodes; when at least one node which received the wakeup message is a relay node, transmitting the wakeup message upon receiving the probe packet from another communication node by the relay node; when the node which received the wakeup message is a destination node, transmitting a suppress message upon receiving the wakeup message by the destination node; when the relay node receives the suppress message, transmitting the suppress message; and when the source node receives the suppress message, transmitting concurrently a data signal to the destination node through the relay node.
Abstract:
Disclosed are a duty cycle control method and apparatus to mitigate latency for duty cycle wireless low-power MAC. The duty cycle control method according to an embodiment of the present invention can control a duty cycle depending on traffic conditions in the asynchronous duty cycle-based low-power MAC to mitigate the packet transmission latency between nodes without significant damage of unique low power characteristics.
