Diagnosing the weakest link in WSN testbeds: A reliability and cost analysis of the USB backchannel

Universal serial bus as a communication medium for prototype networked data acquisition and control systems - performance optimisation and evaluation

“…Other authors present applications of multinode USB networks for various data collecting or control purposes, including industrial systems, home automation, or virtual instrumentation for power monitoring [10], [11], [12], [13], but do not investigate system performances extensively. Such a study can be found in [14], while the problem of nodes synchronisation is addressed in [15], [16]. Some authors propose hybrid solutions with the USB bus connecting a host computer and a single controller of another multidrop bus, like RS485, CAN, or I2C [17], [18].…”
