Agriculture is one of the essential commodities to increase food production and economic growth in the world. Food demand is rising day by day as a result of population growth. Existing farming techniques are not suited for increasing food production. To overcome this issue, we use Internet of Things (IoT), which is one of the emerging technologies in the agriculture field. Generally, the IoT devices consist of low power, low processing and low memory capacity. So, energy plays a significant role in extending the lifespan of the network in the Agricultural Internet of Things (AIoT). To increase the lifetime of the network, this paper proposes an Energy-aware Grid-based Data Aggregation Scheme in Routing (EGDAS-RPL) protocol for AIoT. It has three processes, namely grid formation, grid head (GH) selection and grid head parent selection. First, EGDAS-RPL forms the equal-sized grid on the square network. Second, it probabilistically selects the GH node within the grid. Finally, it considers the metric expected transmission count (ETX) to select the optimal GH parent for data transfer. The simulation is conducted using the COOJA simulator. The performance of the proposed EGDAS-RPL protocol is compared to RPL and E2HRC-RPL, which reduces the packet loss ratio and end-to-end delay. Thus, EGDAS-RPL protocol increases the lifespan of the network.

农业是增加世界粮食产量和经济增长的重要商品之一。由于人口增长，粮食需求日益增加。现有的耕作技术不适合增加粮食产量。为了克服这个问题，我们使用了物联网（IoT），这是农业领域中的新兴技术之一。通常，物联网设备由低功耗，低处理能力和低存储容量组成。因此，能源在延长农业物联网（AIoT）中网络的使用寿命方面起着重要作用。为了延长网络的寿命，本文提出了一种用于AIoT的基于能量感知网格的路由数据聚合方案（EGDAS-RPL）协议。它具有三个过程，即网格形成，网格头（GH）选择和网格头父代选择。第一，EGDAS-RPL在方形网络上形成大小相等的网格。其次，它概率地选择网格内的GH节点。最后，它考虑度量标准的预期传输计数（ETX）以选择最佳GH父级进行数据传输。使用COOJA仿真器进行仿真。将提出的EGDAS-RPL协议的性能与RPL和E2HRC-RPL进行了比较，从而降低了丢包率和端到端延迟。因此，EGDAS-RPL协议可以延长网络的使用寿命。将提出的EGDAS-RPL协议的性能与RPL和E2HRC-RPL进行了比较，从而降低了丢包率和端到端延迟。因此，EGDAS-RPL协议可以延长网络的使用寿命。将提出的EGDAS-RPL协议的性能与RPL和E2HRC-RPL进行了比较，从而降低了丢包率和端到端延迟。因此，EGDAS-RPL协议可以延长网络的使用寿命。
