Abstract:
PURPOSE: A method for providing an Internet service in a mobile communication terminal and a device thereof are provided to determine a user interest subject by user data, determine a subject of a service time by collecting Internet service items, and recommend a service according to similarity of subjects. CONSTITUTION: A mobile communication terminal determines a user interest subject from user data(1307). The mobile communication terminal collects service items by connecting a network(1311). The mobile communication terminal determines a subject about the collected service items(1315). The mobile communication terminal determines relation between the user interest subject and the service items(1323). The mobile communication terminal recommends service items by the relation(1325).
Abstract:
PURPOSE: A data copies allocation apparatus in an MANET(Mobile Ad-hoc NETwork) and method thereof are provided to increase the accessibility of data copies between nodes by relatively allocating the data copies. CONSTITUTION: An inquiry processing unit(120) creates inquiry processing information including the information of inquiry processing results and data copies of member nodes for a data sharing group. A selfish character determination unit(150) determines selfish levels of the group member nodes based on an average selfish character index calculated by using the inquiry processing information. A data importance calculation unit(140) determines importance levels of the allocated data copies. A data copies allocation unit(160) allocates data copies to the member nodes according to selfish character levels.
Abstract:
PURPOSE: An apparatus and a method for detecting a selfish node in a MANET, and a data replica allocating method using the same are provided to increase network efficiency and security. CONSTITUTION: A node information transmitting and receiving unit(310) transmits node information about a usable data storage size and a storage data type of the first node to the second node. The node information transmitting and receiving unit receives node information about a usable data storage size and a storage data type of the second node. A selfishness judging unit(320) judges selfishness of the second node in consideration of node information of the second node and network information. The network information comprises the distance of the second node and a communication access frequency to the second node.
