Abstract In this paper we describe and evaluate anenhanced version of an active RFID wake-up and tag IDextraction radio communication protocol. The enhancedprotocol further reduces the transponders’ power consumption(prolonging their battery lifetime). The protocol uses afrequency binary tree method for extracting the identificationnumber of each transponder. This protocol is enhanced byextending it with a framed slotted medium access controlmethod which decreases the number of activations of eachtransponder during tag ID extractions. Using this medium accessmethod, the average number of transponder activations isdecreased with a factor of 2.5 compared to the original protocol.The resulting increase in ID read-out delay is 0.9%, on average.
