In this paper, we present the design of a new sensor node, named Multipurpose EnerGy-efficient Adaptable low-cost sensor Node (MEGAN), with all the desired features such as reconfigurability, flexibility, energy efficiency, and low-cost required to build the Internet of Things (IoT). Apart from the ability to interface a maximum of 32 different sensors and actuators, MEGAN allows a user to choose the desired communication module, depending on the required range of communication. We design a power management circuit to extend the lifetime of the resource-constrained sensor node. Additionally, it has an integrated recharging circuit on board, which can use the energy harvested from any unregulated energy source. MEGAN combats a major drawback of application-specific sensor nodes, because of the integration of switches and a programming port. The flexibility of MEGAN, with respect to the integration of any sensor or actuator, makes it a multipurpose adaptable sensor node. The analysis of the lifetime, received signal strength indicator, packet delivery ratio, adaptability, and reliability of MEGAN under different operating conditions establish the energy efficiency and superiority of its hardware design.

MEGAN：物联网的多功能节能，适应性强且低成本的无线传感器节点

在本文中，我们介绍了一种新的传感器节点的设计，即多用途EnerGy高效适应性低成本传感器节点（MEGAN），它具有构建所需的所有所需功能，例如可重新配置性，灵活性，能效和低成本物联网（IoT）。除了能够连接最多32个不同的传感器和执行器外，MEGAN还允许用户根据所需的通讯范围来选择所需的通讯模块。我们设计了电源管理电路，以延长资源受限的传感器节点的寿命。此外，它在板上有一个集成的充电电路，可以使用从任何未经调节的能源中收集的能量。由于开关和编程端口的集成，MEGAN克服了专用传感器节点的主要缺点。MEGAN的灵活性，就任何传感器或执行器的集成而言，使其成为一个多用途的自适应传感器节点。对MEGAN在不同工作条件下的寿命，接收信号强度指示器，数据包传输率，适应性和可靠性进行分析，可以确定其能源效率和硬件设计的优越性。
