    摘要: An apparatus and method for establishing a routing path in a ZigBee network including a device in sleep mode is provided. The method includes receiving a route request command, and establishing a path with reference to sleep information of a destination device and of all devices located on a path to the destination device. Accordingly, while the devices are allowed to sleep for energy efficiency even in a non-beacon-enabled mode, an ad-hoc on-demand distance vector (AODV)-based mesh routing method which uses a route request command (RREQ) and a route reply command (RREP) can be used as is, and thus the ZigBee network can be utilized in more various application fields.

    摘要: Provided are a method and apparatus for setting a routing path in a wireless sensor network. The apparatus for setting a routing path includes a neighbor table storing information of a peripheral device within wireless communication distance of a transmitter transmitting data; a searching unit sequentially searching whether at least one of an address of a destination, a parent address or ancestor address of the destination representing an address of a receiver receiving data transmitted by the transmitter exists or not in the neighbor table; and a link quality indicator (LQI) judging unit transmitting the data to the receiver when a LQI value of the address is greater than a value that is previously set in a case in which an address is searched in the searching unit.

    摘要: Provided is a method of preventing a data collision that occurs when two or more child nodes simultaneously transmit data to a parent node in a ZigBee network having a tree routing scheme and operating in a beacon mode. In the ZigBee system having the tree routing scheme and operating in the beacon mode, data communication to the parent node is performed in a beacon frame of the parent node. Here, when several child nodes exist under a single parent node, the child nodes transmit data to the parent node at the moment of receiving the beacon of the parent node, so that the data collision may occur when the child nodes simultaneously transmit the data to the parent node in the beacon frame of the parent node. In the method of preventing a data collision, each of the two or more child nodes is set to wait for its guard time (delay time) when transmitting data to the parent node to induce a normal slotted carrier sense multiple access with collision avoidance (CSMA-CA) operation. Therefore, the data collision can be prevented.
