Wireless sensor networks (WSNs) consist of sensor nodes, which can sense, process, and then transfer different types of data into the base station. The major role of sensor nodes is to gather data at regular intervals and then send it into the base station. Designing energy-efficient routing protocols is one of the major challenges in WSNs. In this paper, an energy efficient layered routing protocol (EELRP) is proposed. The proposed method divides the network into some concentric circles of different radii. The circles are divided into eight equal sectors. Sections are created through a crossover between layers and sectors. Each section contains some nodes, and the most appropriate one is selected as the agent. The nodes of each section send the sensed data to their agent. Next, the agent aggregates the data, provides error detection and correction according to the redundant residue number system, and then sends information to the agent of the lower section of the same sector. The procedure continues until the information reaches the base station. On comparing the performance of EELRP with that of conventional methods, one can see that EELRP provides an improvement in the network lifetime, energy consumption, packet delivery rate, and the number of path hops.

无线传感器网络 (WSN) 由传感器节点组成，传感器节点可以感知、处理不同类型的数据，然后将其传输到基站。传感器节点的主要作用是定期收集数据，然后将其发送到基站。设计节能路由协议是 WSN 的主要挑战之一。在本文中，提出了一种节能分层路由协议（EELRP）。所提出的方法将网络划分为一些不同半径的同心圆。圆圈被分成八个相等的部分。截面是通过层和扇区之间的交叉创建的。每个部分包含一些节点，选择最合适的一个作为代理。每个部分的节点将感测到的数据发送给它们的代理。接下来，代理聚合数据，根据冗余余数系统提供错误检测和纠正，然后将信息发送给同一扇区下段的代理。该过程一直持续到信息到达基站。通过将 EELRP 的性能与传统方法的性能进行比较，可以看到 EELRP 在网络寿命、能耗、数据包传递率和路径跳数方面提供了改进。
