Metadata Challenge for Query Processing Over Heterogeneous Wireless Sensor Network

Wireless sensor networks become integral part of the people life. These networks can be used for monitoring the data in various domains due to their flexibility and functionality. Query processing and optimization in the WSN is a very challenging task because of their energy and memory constraint. In this paper, first the authors focus is to review the different approaches that have significant impacts on the development of query processing techniques for WSN. Finally, they aim to illustrate the existing approach in popular query processing engines with future research challenges in query optimization.
