This paper presents a novel grid-based key pre-distribution scheme for wireless sensor networks (WSNs) aiming to improve connectivity and resiliency. Building on previous works, the proposed 3D approach introduces plat-based polynomial assignment. The analysis demonstrates significant advantages over traditional methods, including greater intermediate node availability. Key aspects include connectivity, resiliency comparison, and the limitations of the key establishment phase. The proposed scheme contributes to the field by ensuring higher network performance and stability in real-world applications.
