Abstract
In wireless sensor networks, a data-centric storage scheme (DCS) is one of representative researches to store sensor readings and to process a query efficiently. The DCS scheme assigns distributed data regions to sensor nodes and stores sensor readings to the sensor node which is responsible for the data region to process the query efficiently. However, the existing DCS schemes have some drawbacks that the sensor nodes have the fixed ranges to store sensor readings. Because the ranges of the sensor readings change periodically in real world applications, the existing DCS schemes have problems that they use storage space unevenly in entire sensors and their network lifetimes are reduced. To solve such problems, we propose a context aware data-centric storage scheme to store sensor readings equally in the entire sensor network. To show the superiority of our proposed scheme, we compare it with the existing DCS schemes. Our experimental results show that our proposed scheme improves about 377.7% network lifetime over the existing schemes on average.
