In this paper, the authors propose an efficient data collection algorithm for active RFID (Radio Frequency IDentification)systems. The algorithm can be used for ubiquitous services in maritime logistics adaptation. Conventional algorithms use slotted aloha in ISO 18000-7 or CSMA/CA in DASH 7 mode 2. They show poor throughput performance because they collect all tags at every wakeup round. The proposed algorithm, adapted to maritime logistics, improved the performance by reading the previously collected tags without collision. The newly joined tags are collected by conventional collection algorithm.
