The problem of anti-collision tag is a common problem of the radio frequency identification (RFID) system. ALOHA algorithm and binary search algorithm is the main algorithm to solve the collision problem. This paper analyzes the effectiveness of binary searching of backtracking algorithm in time slot number of shortening identification tags. Combining the theoretical analysis what needs to be improved in binary searching of backtracking algorithm.

With the development of Radio Frequency Identification (RFID) technology, it also exposed some problems in practical applications. Especially in multi-tag anti-collision problem, how to quickly identify multiple tags in the scope of the reader has become the key to solve the problem. On the basis of the Binary Search Algorithm (BSA) and Dynamic Binary Search Algorithm (DBSA), the paper proposed an Improved Dynamic Binary Search Algorithm. The simulation result proves that the improved method in multi-tag anti-collision is more efficiency than the previous two, which is a good solution to the shortcomings of the first two algorithms.

Radio Frequency Identification (RFID) is a kind of information that using radio Identification technology. Anti-collision algorithm has always been a research topic for researchers. The anti-collision algorithm of labels is mainly divided into two major categories: ALOHA-Based Anti-Collision Algorithms and Anti-collision algorithm based on binary search. Both algorithms have their own advantages and disadvantages, Anti-collision algorithm that based on ALOHA is simple and fast, but it will lose labels. Binary-based anti-collision algorithm can be searched for every tag, and it is not easy to lose tags, but it is relatively complicated and has poor security. Therefore, this paper proposes an Anti-collision algorithm which combines the dynamic frame slot Anti-collision algorithm with the return binary search algorithm.

Passive radio frequency identification-based technology is a convincing approach to the achievement of versatile energy- and cost-efficient wireless platforms for future wearable applications. By using two-part antenna structures, the antenna-electronics interconnections can remain non-stressed, which can significantly improve the reliability of the textile-embedded wireless components. In this article, we describe fabrication of two-part stretchable and non-stretchable passive ultra-high frequency radio frequency identification textile tags using electro-textile and embroidered antennas, and test their reliability when immersed as well as under cyclic strain. The results are compared to tags with traditional one-part dipole antennas fabricated from electro-textiles and by embroidery. Based on the results achieved, the initial read ranges of the two-part antenna tags, around 5 m, were only slightly shorter than those of the one-part antenna tags. In addition, the tag with two-part antennas can maintain high performance in a moist environment and during continuous stretching, unlike the one-part antenna tag where the antenna-integrated circuit attachment is under stress.
