Sub-1GHz wireless sensor network
A hybrid control algorithm, which combines channel selection and transmission power control for Sub-1GHz wireless sensor network systems, is proposed in this paper. By measuring and evaluating the status of candidate channels, the hybrid control algorithm can identify a channel with minimal interference for transmission. Moreover, by analyzing link quality estimators and employing a fuzzy controller, the system can adaptively adjust transmission power based on the surrounding environment of nodes. Unstable frequencies can be avoided through frequency hopping, either.
