SYSTEM AND METHOD FOR SECURITY OF NEIGHBORHOOD AREA NETWORK USING NEIGHBORHOOD DETECTION

摘要

PURPOSE: A security system and a method using neighborhood searching in a neighborhood area network to keep security are provided to detect an access from a bad node to block. CONSTITUTION: Access nodes(N20,N21) approach through the predetermined parent node(N2) to a new cluster. A coordinator(C) transmits a neighbor search request in the access node. An expansion ACL frame created by the neighbor search from the access node is received by the coordinator. The neighbor list field of the expansion ACL frame shows the neighbor nodes within one hop. The neighbor node time stamp field shows the time information of the respective allocated radio resource to neighbor nodes.
