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 for determining superframe to efficiently perform beacon scheduling by allocating superframe lengths which are different according to a routing depth of sensor nodes in a ZigBee based wireless sensor network. The method for determining a superframe for beacon scheduling, includes the steps of: receiving a beacon from a neighboring node and grasping information on a superframe used by the neighboring nodes; and determining a transmission time and a length of own superframe based on superframe information of the grasped neighboring node.
