摘要： A terminal device with a function of distributing data, a method and a system for distributing multimedia data using the same are provided. In order to reduce loads of a core network and effectively use a network, the terminal device includes: a storage unit storing data; a data request monitor sensing a request for the data which is transmitted from another terminal device through a network; and a data controller determining whether the requested data is stored in the storage unit in response to the request for the data and transmitting the data to the requesting terminal device through the network when the requested data is stored in the storage unit. Accordingly, it is possible to expect an effect as in a case where a plurality of data severs are installed with low costs.

摘要： A mobile terminal in a sensor network selects one of the sensors nodes in the sensor network as an upstream agent, and piggybacks a list of neighboring sensor nodes found in the upstream agent selection process on an upstream packet and transmits the upstream packet to a gateway through the upstream agent. The gateway in the sensor network selects one of the neighboring sensor nodes as a downstream agent using state information of the neighboring sensor nodes in the list, and transmits a downstream packet to the mobile terminal through the selected downstream agent.

摘要： Provided are a method and apparatus for connecting a sensor network to a heterogeneous network, in which an external network connected to the sensor network functions as a virtual personal area network (PAN) so that the same PAN address system is used between the sensor network and the external network by using a concept of a ‘virtual PAN’. According to the method and apparatus for connecting the sensor network to the heterogeneous network, a node of the sensor network can efficiently communicate with a node of the external network including the heterogeneous network by assigning the virtual PAN address to the node of the external network including the heterogeneous network without inserting any additional layer into the node of the sensor network.
