    摘要: A method for reducing power consumption in a wireless sensor network is provided. An optimized path destined for a sink node is set using a common channel in which first and second nodes use a CSMA scheme. A first channel is set and transmission/reception slots for packet transmission/reception arc allocated in the first channel. A packet is transmitted to the second node through a first transmission slot using a TDMA scheme. When a packet is not received from the second node through a first reception slot within a first set amount of time, the first reception slot is allowed to transition to an inactive state. The first node is one of the sink node, at least one parent node, and at least one child node of the parent node, and the second node is one of child nodes of the first node.

    摘要: A frame structure for piconet master node on/off scheduling and method thereof. The frame structure includes a schedule-based data period, a contention-based active period, a schedule-based schedule notification message period directly following the contention-based active period, and an inactive sleep mode period positioned before the schedule-based data period, before or after the contention-based active period, or after the schedule-based schedule notification message period.
