| Abstract |
| Network security remains a paramount concern in clustering routing protocols due to the risk of eavesdropping. To address these vulnerabilities, this paper presents the Reconfigurable Intelligent Surfaces assist Routing Protocol, a novel approach specifically designed to counter eavesdropper attacks in clustering routing protocols. We propose an analytical closedform solution to determine the optimal RIS phase shifts for the sensed signal, strategically enabling constructive addition with the direct channel at the sink while impeding eavesdroppers through deconstructive addition. In addition to security enhancements, the paper also focuses on improving network lifetime. To achieve this, we introduce the Centralized Energy-Efficient Grid Clustering Protocol (CEGC), which depends on judging matric, called threshold distance.CEGC implements an effective transmission method for intra-cluster communication, ensures uniform cluster sizes for balanced energy consumption, introduces multi-hop communication to save energy, and integrates remaining node energy in the cluster head selection process for better decision-making. Extensive simulations demonstrate the effectiveness of both the RIS Assist Routing Protocol and the Centralized Energy-Efficient Grid Clustering Protocol in achieving their respective objectives. |
