—High accuracy and low cost are challenging requirements for localization in wireless sensor networks (WSNs). The radio interferometric positioning system (RIPS) proposed in [1] aims to meet both requirements at the same time. However, it is vulnerable to channel fading, and suffers from the noise aggravation due to the square operation. In this paper, we(More)
In this demo, an efficient and reliable wireless link is designed for mobile video surveillance systems. In the link, the idea of cognitive radio is utilized and an adaptive channel switching mechanism is employed to avoid unpredictable interferences. Packets pipelining and accumulative acknowledgement (ACK) is proposed based on the stop-and-wait ARQ(More)
