摘要： Provided are a device of a node and method for beacon scheduling in an ad-hoc network and a data transmitting method thereof, which reduce power consumptions of nodes in an ad-hoc network when data communications between the nodes occur frequently. A beacon transmitting node checks its residual power. If the residual power is lower than a predetermined level, the beacon transmitting node notifies a plan to change its beacon cycle to other nodes. Thereafter, the beacon transmitting node increases the beacon cycle and transmits a beacon at the increased beacon cycles. Consequently, the beacon transmitting node can change its beacon cycle dynamically according to its power condition. Thus, the life span of the node can be increased. Therefore, it is possible to reduce an overhead of reconstructing a sensor network.

摘要： Provided are a method for processing reception calls during mobile RFID service processing, and a wireless terminal employing the method. The terminal provides mobile RFID service by receiving tag information from the RFID reader, requesting the object directory server for CS position information based on the tag information, requesting service contents based on the tag information and CS position information. The present invention prevents collision between reception call processing and mobile RFID service processing in the wireless terminal by processing reception call appropriately to each duration of mobile RFID service processing. For example, when a call is received before read command is transmitted to the RFID reader, the RFID reader is turned off and the reception call is processed. When a call is received before CS position information is requested, the CS position information is requested after the reception call is processed.
