Radio frequency identification (RFID) systems are
becoming increasingly popular for automatic object identification
and supply chain management. Wide acceptance of this technology
has led to several new areas of research, one of which is
RFID-enhanced wireless sensor networks (WSNs). Such networks
have the ability to self-organize, identify tagged objects, perform
localization, and carry out searches; all of which are enablers
of pervasive computing. This paper therefore presents various
challenges to creating such networks, and describes our recent
research on energy efficient RFID tag reading protocols.
