ABSTRACT
Embedded wireless sensors complete with sensing, processing, and wireless communication capabilities have unleashed a wide range of sensing solutions for places hard to reach with wires due to hazardous conditions or object mobility. Ÿe removal of cables for traditional wired sensors also means signi¢cant cost reduction. For factory monitoring, wireless sensors are envisioned to be installed on machines, vehicles, and other facilities. A few pilot e¡orts have explored the feasibility of such factory sensing systems [1-4]. While some studies con¢rmed basic wireless sensor operations to be feasible in such settings, others found challenging levels of transmission errors in some machine environments (e.g., [5]). Ÿis chapter examines the nature of this problem and presents approaches for measurement, modeling, and avoidance of transmission errors in one such environment, speci¢cally, in high-speed rotating machines.
