Wireless sensor networks (WSNs) sense and collect information from a desired phenomenon with the help of sensor nodes that have limited computational power, battery, and memory. Several data aggregation approaches are proposed to make the sensor networks energy-efficient, increasing the network’s lifetime by controlling data redundancy at aggregator nodes. Redundant data is suppressed before transmission to the sink. In this work, our aim is to enhance the network lifetime by efficiently utilizing the network’s energy through controlled data redundancy and minimizing data transmission to the sink. Data aggregation occurs in two steps: firstly, within clusters where the cluster-head serves as the aggregation point, and secondly, at a central point in the network where the gateway node acts as the aggregation point. Experiments demonstrate that our proposed approach yields better results compared to a benchmark clustering protocol in terms of network stability, the number of data packets transferred to the destination, energy dissipation of nodes, and overall network lifetime.

无线传感器网络 (WSN) 借助计算能力、电池和内存有限的传感器节点来感知和收集所需现象的信息。提出了几种数据聚合方法来提高传感器网络的能源效率，通过控制聚合器节点的数据冗余来延长网络的寿命。冗余数据在传输到接收器之前被抑制。在这项工作中，我们的目标是通过受控数据冗余和最小化到接收器的数据传输来有效利用网络能量，从而延长网络寿命。数据聚合分两步进行：首先，在簇内，簇头作为聚合点；其次，在网络的中心点，网关节点作为聚合点。
