Binary Tree Slotted ALOHA for Passive RFID Tag Anticollision

Abstract: In order to enhance the efficiency of radio frequency identification (RFID) and lower system computational complexity, this paper proposes three novel tag anticollision protocols for passive RFID systems. The three proposed protocols are based on a binary tree slotted ALOHA (BTSA) algorithm. In BTSA, tags are randomly assigned to slots of a frame and if some tags collide in a slot, the collided tags in the slot will be resolved by binary tree splitting while the other tags in the subsequent slots will wait.

“…This procedure is carried out repeatedly until all collisions are completely resolved, and hence each tag is uniquely identified. M-ary tree concept is also available in literature where the collided tags are divided into M number of subgroups [10][11][12][13] instead of two as in the binary tree algorithm.…”

“…A primeira envolve integrar técnicas baseadas nas propostas de Cui e Zhao (2009) e Wu et al (2013). A segunda faz melhoramentos na estimativa do tamanho inicial de quadro aliada à análise da teoria do acesso aleatório para otimizar a resolução de colisões.…”

“…Caso as respostas não fossem as esperadas ou se não houvesse respostas, concluía-se que as aeronaves não eram amigas, embora isso não significasse que fossem inimigas (Violino, 2005). A tecnologia é utilizada tanto para uma simples aplicação de identificação quanto para aplicações complexas de rastreamento e localização (Wu et al, 2013).…”
