A two-tier integrated RFID/sensor network with a WiFi WLAN
Haleh Khojasteh, Mena Misic, Vojislav B. Mišić · 2012
We investigate the coexistence of Wi-Fi (WLAN) and RFID/sensor networks that use IEEE 802.15.4 standard in the Industrial, Scientific and Medical (ISM) frequency band. To minimize the interference between the networks, a time scheduling scheme is combined with a sleeping scheme for RFID tags/sensors to further reduce the collision rate and energy consumption. We evaluate the performance of our solution under two different scenarios using discrete event simulation.
