A New Dynamic Frame Slotted ALOHA-Algorithm for Anti-Collision in RFID Systems
Dynamic ALOHA-algorithm is an anti-collisionalgorithm highly concerned in RFID system.After we analyzedthe existing ALOHA-algorithm,a new dynamic frame slottedALOHA-algorithm was proposed,which can dynamicallychange frame length through the feedback of the last collisionslot number in one inventory frame.The simulation indicatesthat this algorithm has nearly the same performance evaluationon system efficiency and less total number slots requiredidentifying tags,compared to the estimating real-time tagquantity near the readers.Especially this algorithm is simplefor RFID system application and keeps compromise betweenefficiency and complexity.
