In-network RFID Data Filtering Scheme in RFID-WSN for RFID Applications

摘要: In the integration of wireless sensor networks (WSN) and radio frequency identification (RFID), RFID data can use WSN protocols for multi-hop communication. Due to readers overlapped regions in dense areas due multiple read cycles, a lot duplicate is produced. Transmitting such duplicates towards base station waste node energies. In-network filtering these save transmission overhead, but on other hand it increases computation cost. Delay an important parameter applications that has not been considered yet by existing approaches. Both communication overhead affect delay performance terms queuing processing respectively. Therefore, required tune algorithm. this paper, our in-network scheme tend find trade-off between two costs better performance. simulation part, we showed effect
