摘要： A hybrid channel assignment method comprising the steps of negotiating among routers to select one router to act as a central server; collecting, at the selected router, information on an entire network transmitted from the other routers, and assigning channels based upon the information on the entire network; and reassigning channels of respective routers based upon dynamically-changing traffic characteristics. The hybrid channel assignment method can assign channels using both centralized processing and distributed processing in order to ensure optimally correct channel assignment consistent with present traffic characteristics. This as a result can prevent network resources from being wasted and also increase network capacity, thereby optimizing effective use of the network resources.

摘要： A system and method for exactly estimating a volume of traffic is provided when packets are transferred within the network. The system and method receive data packets from clients through a plurality of router-for-clients, and creating a flow information packet for estimating information about a flow, transfer the data packets and the created flow information packet to the destination router-for-client via a router-for-relay, calculate information about the traffic of a flow at the destination router-for-client through the flow information packets transferred from the router-for-clients, and estimate a volume of the traffic. Thus, the system and method can estimate the volume of the traffic on the network with respect to the aggregated flow defined by the router pair connected to the terminal or the external network when the traffic is actually introduced into the network, instead of the flows of each terminal and each destination.

摘要： Technology for a wireless multi-hop network is disclosed. a plurality of nodes in the wireless multi-hop network are synchronized to a period sequentially including a first interval and a second interval and are in an active state at the start time of the first interval. a node transmits a control frame at the start time of the first interval, the control frame indicating that data will be transmitted in the second interval, and then transitions to a sleep state which is maintained until a wake-up time in response to determining that the control frame has been successfully received by a next hop node. The wake-up time is a point in time when a node transitions to an active state to transmit the data and is present in the second interval.

摘要： An apparatus for displaying network status includes a network traffic collection unit, a network status display unit and a first attack type determination unit. The network traffic collection unit analyzes packets collected from an external communication network, and outputs connection information including a source Internet Protocol (IP) address, a destination IP address and a destination port number. The network status display unit receives the connection information transmitted from the network traffic collection unit for a predetermined period, and displays the connection information in a coordinate point data form on a three-dimensional rectangular coordinate system whose three axes are assigned to a source IP address, a destination IP address and a destination port number, respectively. The first attack type determination unit detects the coordinate point data displayed on the network status display unit as a line or plane through image processing, and determines an attack type according to the type of the line or plane.
