摘要： A communication method and apparatus using a virtual sink node in a wireless sensor network, in which location information about a destination node is acquired by a source node. If the location of the destination node is out of a transmission range of the source node, data including the location information about the destination node are transmitted from the source node to one of nodes adjacent to the source node, where the one node is typically closest to the destination node. The data are transmitted from the one node to another one of nodes adjacent to the one node, where another node is closest to the destination node, until the destination node is located within a transmission range of the one node. If the destination node is located within the transmission range of the one node, the data are transmitted from the one node to the destination node.

摘要： A communication method and apparatus is disclosed that uses a received signal strength indicator (RSSI). In a sensor network including a plurality of nodes, a first node of the plurality of nodes receives a signal transmitted from a second node of the plurality of nodes, at least once. The first node also manages a link state with the second node according to the RSSI of the received signal. Therefore, the first node can receive signals from the plurality of nodes and then predict whether the second node moves. The first node can also predict a link state after the second node is moved so that communication can be performed through a link in a good state. Accordingly, the communication quality and the network performance of a network are enhanced.

摘要： Methods and apparatuses for detecting and recovering from a buffer overflow attack are provided. A method of recovering an operation state of a processor from a buffer overflow attach includes: detecting whether a buffer overflow attack is made on any write operation while storing write operations that are potential targets of buffer overflow attacks in a predetermined location instead of an original destination to store write operations; storing the contents stored in the predetermined location at a predetermined interval in the original destination for storing write operations if no buffer overflow attack is detected and discarding unsafe write operations subsequent to a buffer overflow attack if a buffer overflow attack is detected; and ignoring the unsafe write operations subsequent to the buffer overflow attack if a buffer overflow attack is detected. Therefore, a buffer overflow attack occurring in a computer can be effectively detected, and damage of a system which is attacked can be minimized and the system can be recovered or return to the original state before the attack. A system can be effectively protected while minimizing reduction in performance of the computer system according to a method used to implement the present invention, thereby greatly improving the environments under which the computer and the Internet are used.

摘要： A method for gating a clock signal to an execution unit on long latency memory stalls monitors a stall signal, a scoreboard (data) hazard signal, a resource hazard signal, and a data return signal. The clock signal is decoupled from the execution unit when the stall and data hazard signals are asserted for a selected interval and the data return and resource hazard signals are not asserted for a selected interval.

摘要： Provided are a communication method and system for sensor network. In reporting event occurrence in a real-time sensor network application, a cycle time is divided into an event announcement period and a data transmission period to provide real-time transmission performance and energy efficiency. Each of the periods is again divided into the number of slots equal to the maximum depth of a network. Respective nodes sequentially operate according to their depths in a routing tree during the event announcement period to receive the signal transmitted from the lower node. To remove sleep delay, a slot next to the signal reception slot becomes a signal transmission slot. A node sensed an event transmits a signal informing event occurrence during its signal transmission slot, and this signal includes only the address of the transmission node. When a signal does not exist in the event announcement period, no traffic occurs in the data transmission period and the upper nodes maintain a sleep state. When a signal is transmitted during the event announcement period, nodes transmitting/receiving a corresponding signal operate during the data transmission period to transfer data packets.
