Energy-Efficient Polling Protocols in RFID Systems

Future RFID technologies will go far beyond today's widely-used passive tags. Battery-powered active tags are likely to gain more popularity due to their long operational ranges and richer on-tag resources. With integrated sensors, these tags can provide not only static identification numbers but also dynamic, real-time information such as sensor readings. This paper studies a general problem of how to design efficient polling protocols to collect such real-time information from a subset M of tags in a large RFID system.
