Data management solutions in networked sensing systems

Abstract

Since the emergence of sensor oriented applications, sensor data management has become a very active research domain. We can distinguish three classes of solutions in this area, which we will explore in this chapter. The first is sensor networks which provide distributed processing of sensor data. The second is data stream management systems which are centralized systems that deal with stream data flowing from sensors. And finally, some hybrid approaches have also recently appeared which aim to integrate these two different types of solutions. This chapter provides an overviewof these three groups of proposals and discusses their approach to deal with issues such as scalability of sensing systems, heterogeneity of sensors and processing complex operations on sensor data stream. © 2010 Springer-Verlag Berlin Heidelberg.
