The use of Radio Frequency Identification (RFID) technologies is growing. RFID enables data to be collected from many objects, for identification and other purposes. One of the main disadvantages in tag identification, known as the tag collision problem, is becoming significant, since it leads to the increase in the number of transmitted bits and identification time. The window methodology is created with the aim to manage the number of transmitted bits by the tags. As a result, tags transmit exclusively the bits defined by the window instead of sending their full ID value on every response. This paper presents a protocol with a standardized window. The window size is transmitted as the exponent of power of 2. Simulations show that the proposed solution with standarized window size reduces the number of bits transmitted by the reader, with respect to other protocols using the window, which results in a lower number of total bits in the identification process.
