Abstract: In a sensor network system including at least one sensor node and at least one actuator node, a group is formed based on attribute of each node. Sensing data is shared among the nodes in the group, and each node performs autonomous processing to process an event by comparing the sensing data with a preset event threshold value.

Abstract: In a wireless sensor actuator network system, actuators to be actuated to correspond to a plurality of sensors are selected using an A-S matrix that represents relationship strength between a plurality of actuators and the plurality of sensors based on sensing data of the plurality of sensors, and only the selected actuators determine actuation values based on values of the A-S matrix.

Abstract: A method for transferring data in a method for transferring data signals by a data communication system comprising at least one node, the method comprises: transmitting a wakeup message when a source node receives a probe packet from at least one of other communication nodes; when at least one node which received the wakeup message is a relay node, transmitting the wakeup message upon receiving the probe packet from another communication node by the relay node; when the node which received the wakeup message is a destination node, transmitting a suppress message upon receiving the wakeup message by the destination node; when the relay node receives the suppress message, transmitting the suppress message; and when the source node receives the suppress message, transmitting concurrently a data signal to the destination node through the relay node.

Abstract: A method for transmitting, storing and managing data by compressing data packets to be transmitted and received over an advanced metering infrastructure (AMI) network with low-capacity memory and low-transfer rate. A number of transmission packets may be reduced using at least one of a bitmap interval algorithm that assigns a bitmap value to each interval, thereby reducing a number of request packets, a repeated-bitmap interval algorithm that represents sequential data values as bitmap values by toggling a bit value between 0 and 1 in each data value when a change occurs in the sequential data values, and a run-length encoding algorithm that compresses data by encoding run length of sequential identical data.
