摘要

无线传感器网络(WSNs)由于具有成本效益、可扩展性、灵活性和自组织等优点,越来越多地应用于不同的应用领域。降低节点功耗以使节点寿命最大化的算法和机制是当前的一个研究热点。为此,本文提出了一种基于两个模糊控制器来确定休眠时间和传输功率的方法。仿真结果表明,相对于使用固定的睡眠时间和传输功率,设备寿命增加了30%,相对于仅调整睡眠时间的最先进的工作,设备寿命增加了25%。

A parallel fuzzy scheme to improve power consumption management in Wireless Sensor Networks
Wireless Sensor Networks (WSNs) are increasingly used in different application fields thanks to several advantages such as cost-effectiveness, scalability, flexibility and self-organization. A hot research topic concerns the study of algorithms and mechanisms for reducing the power consumption of the nodes in order to maximize their lifetime. To this end, this paper proposes an approach based on two fuzzy controllers that determine the sleeping time and the transmission power. Simulation results reveal that the device lifetime is increased by 30% with respect to the use of fixed sleeping time and transmission power and by 25% with respect to a state-of-the-art work that adjusts only the sleeping time.
