Abstract

To improve the performance of the wireless powered sensor network (WPSN), this paper proposes a frequency division duplex (FDD)-based on-demand energy transfer protocol and an energy-aware polling-based medium access control (MAC) protocol, called composite energy and data first (CEDF), by using the numbers of data packets and energy packets to determine polling priorities. The performance of the proposed MAC protocol, i.e., CEDF, along with the on-demand energy transfer protocol was evaluated through simulations, with comparison to the closely related protocols such as the round robin (RR) and data first (DF) polling protocols. Compared with RR and DF, our proposed CEDF performs much better in terms of throughput, data packet loss rate, and delay. Additionally, the doubly near-far problem in WPSNs under our proposed on-demand energy transfer protocol and CEDF was investigated to come up with good solutions to alleviate such a problem.

摘要

为了提高无线供电传感器网络（WPSN）的性能，本文提出了一种基于频分双工（FDD）的按需能量传输协议和一种基于能量感知的轮询式媒体访问控制（MAC）协议，称为复合能量和数据优先（CEDF），通过使用数据包和能量包的数量来确定轮询优先级。通过仿真评估了所提出的 MAC 协议（即 CEDF）与按需能量传输协议的性能，并与类似的协议（如轮询（RR）和数据优先（DF）轮询协议）进行了比较。与 RR 和 DF 相比，我们提出的 CEDF 在吞吐量、数据包丢失率和延迟方面表现更好。此外，还研究了我们提出的按需能量传输协议和 CEDF 下的双近-远问题，以提出缓解该问题的有效解决方案。
