Abstract

Various control applications such as aerospace vehicles and automotive control systems can benefit from lower weight and cost. Replacing wired feedback control with wireless sensor and actuator networks (WiSAN) offers attractive features by improving upon the weight and cost problems, while posing new challenges due to the delayed noisy feedback links. Addressing these challenges requires modeling and simulation of WiSAN with noise and delay implemented in the feedback path. A model with Additive White Gaussian Noise and Constant Delay (AWGN-CD) is used in this research. This study provides insight for designing WiSAN for a variety of scenarios, where weight and cost is of concern.
