WizBee: Wise ZigBee Coexistence via Interference Cancellation with Single Antenna PROJECT TITLE :WizBee: Wise ZigBee Coexistence via Interference Cancellation with Single AntennaABSTRACT:Coexistence of Wi-Fi and ZigBee in two.4 GHz ISM band may be a long standing and difficult downside. Previous solutions either require modifications of current ZigBee protocols or Wi-Fi re-configurations, which is not possible in giant-scale wireless sensor networks. In this paper, we have a tendency to present WizBee, a coexistence system using single-antenna sink while not changing current Wi-Fi and ZigBee design. WizBee relies on an observation that Wi-Fi signal is concerning 5 to 20 dB stronger than ZigBee signal in symmetric space, which leaves a lot of room for applying interference cancelation technique to mitigate Wi-Fi interference, and extract ZigBee signals. But, we have a tendency to want to cancel the Wi-Fi interference perfectly for residual ZigBee signal decoding, which needs more correct channel coefficient across data transmissions despite cross technology interference. For strong and accurate Wi-Fi decoding, we use soft Viterbi decoding with weighted confidence worth over interfered subcarriers. Consequently, our answer uses decoded information for channel coefficient estimation instead of standard coaching symbol based mostly ways. The key insight is that, the signal recovery chance for cross technology coexistence, lies in multi-domain info, such as power, frequency and coding discrepancies. Using these data properly can improve the coexistence network throughput effectively. We tend to implemented WizBee in USRP/GNURadio software radio platform, and studied the decoding performance of interference cancelation technique. Our in depth evaluations below real wireless conditions show that WizBee improves ZigBee throughput up to , with median throughput gain of . Did you like this research project?
