Abstract
Provided are a node update system using virtual partition technique and a control method thereof. A storage region of a sensor node is divided into a non-updatable invariable region and an updatable variable region to be virtually generated according to an execution operation of the sensor node. The states of the sensor nodes are monitored, and an update request signal is transmitted to a corresponding sensor node when update is necessary. Execution image information is received, and the execution image information is stored in the variable region to update an execution image, according to a response signal to the update request signal.
Claims15
A node update system using virtual partition technique for updating execution images of a plurality sensor nodes constituting a wireless sensor network, the node update system comprising:
- an update management server transmitting an update request signal for the performance of the update procedure, and transmitting execution image information to be stored in a variable region of the sensor node to a corresponding sensor node to control an update of the corresponding sensor node upon reception of a response signal.
A control method of a node update system using virtual partition technique for updating execution images of a plurality sensor nodes constituting a wireless sensor network, the control method comprising:
- virtually generating a non-updatable invariable region and an updatable variable region into which a storage region of a sensor node is divided, according to an execution operation of the sensor node;
- monitoring states of the sensor nodes, and transmitting an update request signal to a corresponding sensor node when update is necessary;
- and
- receiving a transmitted execution image information, and storing the execution image information in the variable region to update an execution image, according to a response signal to the update request signal.
