Method of context aware data-centric storage for wireless sensor networks

摘要

There is provided a method of context aware data-centric storage for dynamically changing a data storage range comprising: collecting data from entire sensor nodes, after establishing a data storage range of an entire sensor network, dividing areas, and transmitting a message of data storage range information to the entire sensor nodes by a base station; storing the collected data in a storage sensor node by determining whether there is a node responsible for storing the collected data to carry out operation depending on the determination result; determining whether the data storage has not been carried out for a period of time longer than a specified time in each sensor node after storing the data; and to determining whether the scale of invalid range is not smaller than Gamma.
