The propagation of radio signals is affected by several factors that contribute to the degradation of its quality. The effects of these factors are more significant on the propagation of wireless signals with low-power radios, typically used in Wireless Sensor Networks (WSNs). Consequently, radio links in WSNs are often unpredictable. In fact, their quality fluctuates over time and space and connectivity is typically asymmetric. However, it is well known that three factors lead to link unreliability, namely: the environment, the interference and hardware transceivers.
