Apparatus and method for detecting selfish node in MANET, and data replica allocation method using thereof

摘要

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.
