    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.
