在具有挑战性的环境中部署基于能量收集的无线传感器节点（WSNs）通常意味着我们无法精确控制节点的位置和方向。本文介绍了一种新型的智能无线传感器网络，其操作不依赖于它的位置和方向。所提出的无线传感器网络单元是一个立方体形状的设备，其每一侧是一个完整的无线传感器模块，与其他面共享公共能量存储和公共通信总线。本文基于“最强能量面”和“最强无线面”的概念，设计了一种节能算法。“所提出的算法促进了立方体各面之间的能量和信息共享，其共同目标是从所有面收集最大可能的能量，将能量聚集在共享能量总线上，然后使用最强的无线电面将感测到的信号传输到基站。该概念在使用现成组件构建的50 cm（3）实验室原型中得到验证。实验结果表明，即使在最坏的情况下，只有一个面（可能不是发射面）正在收集能量，该设备也能成功传输感测数据。
Deploying energy harvesting-based wireless sensor nodes (WSNs) in challenging environments often means we do not have precise control over the placement and orientation of the nodes. This article introduces a novel smart WSN whose operation does not depend on its placement and orientation. The proposed WSN unit is a cube-shaped device, each side of which is a complete wireless sensor module, sharing a common energy storage and a common communication bus with the other faces. In this article, an energy-efficient algorithm is designed based on the concepts of "strongest energy face" and "strongest radio face." The proposed algorithm facilitates energy and information sharing among the faces of the cube with the common goal of harvesting the maximum possible energy from all sides, aggregating the energy on the shared energy bus, and then, using the strongest radio face to transmit the sensed signal to the base station. The concept is verified in a 50-cm(3) laboratory prototype built with off-the-shelf components. The experimental results show that the device successfully transmits the sensed data even in the worst case where only one face, which may not be the transmitting face, is harvesting energy.
