Wireless sensor networks (WSNs) have grown in popularity as a network method. However, owing to the broadcast communication method and unsupervised deployment nature of WSNs, the Sensor Nodes (SN) often becomes targets of attackers. Due to the few processing and energy resources, basic data aggregation methods such as averaging are required. While it may prevent sensitive data from being hacked, it requires regular message exchanges across a network, imposing a significant burden on SNs with limited resources. This article presents the SDA-SEECH technique for securely transmitting data without collusion attacks to address these concerns. The recommended system has improved collusion resistance, accuracy, and convergence speed. The SEECH algorithm is used to perform energy-efficient clustering. The optimal path was determined using the SEECH Route and HOP-TIME algorithms. Theoretical study and simulation measurement demonstrates that the proposed aggregation methods outperform existing protocols regarding privacy protection and communication efficiency.
