Improving performance with Initial number of tag estimation scheme for the RFID System

In the RFID Sytem, When leaders recognize the tag, a anti-collision scheme is an important factor in the performance of the system. Probabilistic-based anti-collision scheme using the slot status is a technique to estimate the number of tags. the schemes to quickly and accurately estimate the number of tags has been a lot of research. However, A initial number tag are not considering in the number of tags unknown environment. In the paper, estimation scheme for the initial number of tag is proposed to solve the problems. we analyze the performance by the initial number of tag and the proposed scheme.
