摘要:
The coordinator broadcasts a candidate inquiry request command while having a list of candidate coordinators performing a coordinator role. The candidate coordinators receive the candidate inquiry request command, one of the candidate coordinators broadcasts a candidate notifying command, and other candidate coordinators check whether the candidate notifying command has been received. Devices check whether the candidate notifying command has been received from the candidate coordinator, and broadcast a candidate inquiry information command including the candidate notifying command receipt information. The candidate coordinator checks whether the candidate inquiry information command has been received, and broadcasts a candidate inquiry response command including number of accessible devices and the candidate notifying command receipt information. The coordinator receives the candidate inquiry response command and estimates communication performance ranks for the respective candidate coordinators.

In the present invention, an expert system is coupled to the fault management function of a switching system for diagnosing various faults which occur in an electronic switching system and an interface module is coupled to the expert system, so that a user can diagnose a fault of the switching system and monitor a result of the fault. The expert system of the present invention has a knowledge base including information relating to faults of the switching system and when a fault occurs in the switching system, the expert system outputs information of the fault occurrence to a multimedia screen so that a user can recognize a fault immediately and diagnose the fault of the switching system.

The present invention relates to a collaboration system and method among heterogeneous nomadic/mobile communication networks using a grid service. By using a system in which GSI (Grid Service Infrastructure) is overlaid on heterogeneous nomadic/mobile communication networks, access to resources that are accessible with different interfaces can be made with a single standard interface. Further, a vertical hand-off among heterogeneous networks and access to location information can be easily performed. In addition, mutual operationality among networks can be improved and an efficient collaboration environment can be constructed.

Disclosed is an apparatus using a battery and a passive device, and a communication method thereof. In the wireless communication system, a coordinator has an active communication device for supporting active communication, and a passive device for supporting passive communication to wirelessly transmit power to a communication device. The communication device includes a memory and a passive communication device using the power received from the coordinator in a wireless manner in the active communication device operated with the battery, and stays in a passive communication idle state during a period allowing passive communication. The operation of the passive communication device is transmitted to the active communication device via an interrupt device so as to cause an active/passive communication state transition depending on the communication state.

摘要:
Disclosed is a method for controlling unidirectional link connection in a mobile ad hoc network which comprises: mobile nodes including transmission power information in a beacon message that is periodically transmitted; using the information to sense a unidirectional link and maintain residual power information with regard to the corresponding node, and providing unidirectional link connectivity in the link layer to an upper layer through a filtering process using broadcasting and residual power information. Hence, the unidirectional links generated in the mobile ad hoc network may be accurately sensed using transmission power loss on a transmission path, and the frames generated in the link layer in the reverse direction of the unidirectional links may be transmitted.
