智能基础设施具有许多吸引人的功能。收集信息的嵌入式传感器对于决策至关重要。然而，如果传感器在施工时物理嵌入基础设施中，则电子传感器的寿命是对基础设施寿命的限制。在本文中，我们研究了自供电的无线传感器网络，从环境中的机械振动收获能量。提出了一种动态的、层次化的算法MEGA，该算法根据剩余能量和能量收获率来构造簇并选举簇头。以智能桥梁为应用实例，仿真研究验证了该协议的有效性。
Smart infrastructure is attractive for many desirable features. Embedded sensors that collect information are critical for decision making. However, the lifetime of electronic sensors is a constraint to infrastructure lifetime if sensors are physically embedded in the infrastructure at construction time. In this paper, we studied a self-powered wireless sensor network that harvests energy from mechanical vibration in the environment. A dynamic, hierarchical algorithm called MEGA is proposed that constructs clusters and elects the cluster head based on residue energy and energy harvest rate. Taking a smart bridge as an application example, the simulation study has verified the effectiveness of the proposed protocol.
