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.
