Power Control Algorithm of Internet-of-Things Node Based on Vague Set

Abstract

Wireless sensor network is the absolutely necessary infrastructure for the internet of things. Aiming at the energy storage and power control problem of nodes in internet of things, this paper analyzes detailedly some typical power control algorithms and its effects to network performance, and proposes a power control algorithm of nodes in internet of things based on vague sets. Use vague sets theory to optimize the parameters of traditional PID controller, and apply it to power control of nodes in internet of things. The result shows that the wireless network nodes can adaptive control its power, reaching the purpose of reducing energy consumption, and communicating reliably and highly efficient.
