A Self-Configurable Power Control Algorithm for Cognitive Radio-Based Industrial Wireless Sensor Networks With Interference Constraints
With the growth of different design goals and application requirements, Wireless Sensor Networks (WSNs) are receiving sustained attentions in the recent low-cost industrial automation systems. Moreover, Cognitive Radio (CR) technology gives one a possibility to maximize the utilization efficiency of the limited spectrum resources. However, because the wireless devices coexist in the same radio environment, there are harmful channel conflicts among users, and the increasing radio systems causes great contribution to the increasing energy consumption. In order to realize the industrial circumstance, the authors complete three major works in this paper.
