在物联网（IoT）应用中，IPv6网络和无线供电传感器网络（WPSN）之间的跨网络IPv6分组广播已经变得越来越有用（例如，智能农场的应用）。但其数据传输的可靠性和效率仍有待提高。在本文中，我们提出了一个可靠的和高效的IPv6分组广播协议的IEEE 802.15.4为基础的WPSN，命名为6WPSN。首先，给出了无线传感器网络的工作原理，其中采用线性网络编码来提高无线传感器网络中弱链路的可靠性。然后结合射频能量源和线性网络编码建立了性能分析模型。在此模型的基础上，我们制定了一个优化问题，最大化网络效用，这是定义为能源效率和吞吐量的加权和。关键参数（即，每个广播组中的IPv6分组的数量、每个IPv6分组的片段的数量、以及广播数据速率）然后针对6WPSN被联合优化。在效用函数中适当设置权重系数的大量数值结果表明，所提出的6WPSN在能量效率和吞吐量方面显着优于现有的固定数据速率的方法。
In the Internet of Things (IoT) applications, cross-network IPv6 packet broadcast between the IPv6 network and the wireless powered sensor networks (WPSNs) has become increasingly useful (e.g., applications of smart farms). However, its data transmission reliability and efficiency still have to be improved. In this paper, we present a reliable and efficient IPv6 packet broadcast protocol for IEEE 802.15.4-based WPSNs, named 6WPSN. First, the operations of the 6WPSN are given, in which linear network coding is applied to enhance the reliability of weak links in WPSNs. Then the performance analysis model is established that combines with radio frequency (RF) energy supply and linear network coding. Based on this model we formulate an optimization problem that maximizes the network utility, which is defined as the weighted sum of energy efficiency and throughput. The key parameters (i.e., the number of IPv6 packets in each broadcast group, the number of fragments of each IPv6 packet, and the broadcast data rate) are then jointly optimized for the 6WPSN. Extensive numerical results with proper settings of the weight coefficients in the utility function show that the proposed 6WPSN significantly outperforms existing methods with fixed data rates in terms of energy efficiency and throughput.
