The issue of energy balancing in Wireless Sensor Networks is a pivotal one, crucial in their deployment. This problem can be subdivided in three areas: (i) energy conservation techniques, usually implying minimizing the cost of communication at the nodes since it is known that the radio is the biggest consumer of the available energy; (ii) energy-harvesting techniques, converting energy from not full-time available environmental sources and usually storing it; and (iii) energy transfer techniques, sharing energy resources from one node (either specialized or not) to another one. In this article, we survey the main contributions in these three areas and identify the main trending topics in recent research. A discussion and some future directions are also included.
无线传感器网络中的能量平衡问题是一个关键问题，对其部署至关重要。这个问题可以细分为三个方面：（i）节能技术，通常意味着最小化节点通信的成本，因为众所周知，无线电是可用能源的最大消耗者；（ii）能量收集技术，从非全时可用的环境源转换能量，并通常进行存储；以及（iii）能量转移技术，从一个节点（专门或不专门）共享能源资源到另一个节点。在本文中，我们调查了这三个领域的主要贡献，并确定了最近研究中的主要趋势话题。还包括讨论和一些未来的方向。
