Abstract

Limited energy and reliable data transmission are two key issues in Wireless body area networks (WBANs). The utilization of energy harvesting technology has alleviated the energy problem in WBANs, making continuous operation possible. However, Energy Harvesting WBANs (EH-WBANs) face new challenges. How to design efficient data transmission mechanisms taking into account the unstable energy harvesting conditions and dynamic network topology has become crucial. The efficiency of data transmission mainly depends on the network layer and media access control (MAC) layer. Therefore, this paper surveys the routing and MAC protocols proposed for EH-WBANs. There are some surveys on routing and MAC protocols for traditional battery-powered WBANs. However, these mechanisms cannot be directly applied to EH-WBANs due to the randomness and time-varying nature of the energy obtained by energy harvesting, which differs from the energy characteristics of nodes powered solely by batteries. In addition, due to the dynamic network topology and heterogeneous nodes in WBANs, the research results on routing and MAC protocols for Energy Harvesting Wireless Sensor Networks (EH-WSNs) cannot be directly applied to EH-WBANs. Thus, unlike previous surveys, this paper focuses on protocols specifically designed for EH-WBANs. It introduces and analyzes these protocols, summarizes the comprehensive performance metrics and efficient measures for data transmission mechanisms in EH-WBANs, and conducts a comprehensive performance analysis on the protocols proposed for EH-WBANs based on these metrics. This paper intends to provide assistance in addressing the energy and reliable data transmission issues in WBANs, thereby enhancing the applicability of EH-WBANs.

能量采集无线体域网络中的高效数据传输机制：调查

有限的能量和可靠的数据传输是无线体域网（WBAN）的两个关键问题。能量收集技术的应用缓解了无线体域网的能量问题，使其能够连续运行。然而，能量收集无线局域网（EH-WBAN）面临着新的挑战。如何在考虑不稳定的能量收集条件和动态网络拓扑的情况下设计高效的数据传输机制变得至关重要。数据传输的效率主要取决于网络层和媒体访问控制（MAC）层。因此，本文研究了为 EH-WBAN 提出的路由和 MAC 协议。目前已有一些针对传统电池供电无线局域网的路由和 MAC 协议的研究。但是，这些机制不能直接应用于 EH-WBAN，因为通过能量收集获得的能量具有随机性和时变性，与仅由电池供电的节点的能量特性不同。此外，由于无线局域网中的动态网络拓扑和异构节点，针对能量收集无线传感器网络（EH-WSN）的路由和 MAC 协议的研究成果无法直接应用于 EH-WBAN。因此，与以往的研究不同，本文重点关注专为 EH-WBAN 设计的协议。本文介绍并分析了这些协议，总结了 EH-WBAN 中数据传输机制的综合性能指标和高效措施，并根据这些指标对为 EH-WBAN 提出的协议进行了综合性能分析。本文旨在为解决 WBAN 中的能量和可靠数据传输问题提供帮助，从而提高 EH-WBAN 的适用性。
