ABSTRACT

This chapter discusses the issues of building link metrics and the associated data aggregation schemes that realize routing for signal processing (RfSP), review RfSP protocols, and discuss the potential of and challenges facing RfSP. Research on RfSP protocols can be best represented. Signal processing (SP) is the process of information extraction or decision making by analyzing relevant observational or experimental data. SP such as estimation and detection is fundamental to numerous applications in wireless sensor networks such as environmental monitoring, industrial control, and military surveillance. The chapter also discusses the general introduction to RfSP and discuss issues of building link metrics and the associated data aggregation schemes that one has to address in developing RfSP protocols. RfSP protocols further exploit the potential of distributed SP schemes. In addition to energy-efficient data delivery via distributed processing, the issue of where to collect these data is addressed in RfSP.
