Abstract: An apparatus for generating a virtual tuple and a method thereof are provided to make the virtual tuple by extracting the original tuple which satisfies a predetermined condition corresponding to a reference attribute value, and then performing a virtual selection operation by using the original tuple. An extraction module(210) extracts the original tuple corresponding to a reference attribute value. An operating module(220) generates a virtual tuple corresponding to the reference attribute value by using a virtual selection operation. If a predetermined condition is not satisfied, a control module(230) deletes a virtual tuple request and then transmits the request to the other sensor node through a transmitting/receiving module. A storage module(240) stores an attribute value, the actual tuple corresponding to the attribute value and the reference attribute value which a user sets up.

Abstract: A method and an apparatus for improving routing performance in an ad hoc network are provided to start a route recovery process in a destination node not in a source node when a data transmission route is lost by movement or errors of a node, thereby minimizing overload and data packet loss caused by a control traffic generated during the route recovery process. A routing node senses a route error generated on a transmission route. The routing node, sensing the route error, performs a route error notification process(S204). The route error notification process transmits a route error packet to a source node and a destination node located on the transmission route. The destination node receiving the route error packet performs a route searching process(S206). The source node receiving the route error packet performs a route recovery process(S208).
