EcoMesh House Edition : An Energy-Autonomous, Sticker-Thin Distributed Micro-Node Mesh Architecture with Spatial-Aware Attenuation-Penalized Routing (SA-APR) Advanced Research Specification, Protocol Design, and Cryptographic Tunneling FrameworkAuthor: Adv. Sanjay Vidya Vijay Gurav (B.Com., LL.B., B.A. Psychology) Authors: Independent Research & Development Initiative Repository Target: Zenodo (Open Access Pre-print / Technical Specification) Date: November 2026 Abstract Traditional Wi-Fi range extension architectures (e.g., active wall plug repeaters and standard multi-hop mesh nodes) suffer from severe limitations including high continuous power consumption (5\text{W} to 12\text{W} AC), multi-hop bandwidth degradation, and rigid placement restricted by electrical outlet availability. This paper introduces EcoMesh, a novel, sticker-thin (<2.5\text{ mm} thickness), energy-autonomous micro-node mesh architecture that harnesses indoor ambient illumination via printed amorphous silicon photovoltaic cells, buffers charge using solid-state micro-supercapacitors, and coordinates packet delivery via an ultra-low-power RISC-V SoC. Furthermore, we formulate Spatial-Aware Attenuation-Penalized Routing (SA-APR), an advanced routing protocol designed to dynamically bypass heavy architectural obstacles (such as reinforced concrete walls) by evaluating spatial attenuation gradients. Theoretical analysis confirms a sustainable steady-state energy balance where active radio duties remain under 0.24\%, ensuring infinite operational lifespan without battery maintenance. 1. Introduction & Background Indoor wireless connectivity is frequently bottlenecked by structural attenuation (drywall, brick, and reinforced concrete) and the spatial inflexibility of traditional hardware repeaters. Standard repeaters consume continuous line power and exhibit a 50\% throughput drop due to half-duplex relay retransmissions. To resolve these architectural flaws, this paper proposes the EcoMesh Micro-Node Framework, combining flexible printed electronics, ambient indoor solar energy harvesting, micro-supercapacitor storage, and spatial-aware mesh routing. 2. System Architecture & Visual Schematics To illustrate the physical layout, energy flow, and spatial routing mechanics of the EcoMesh micro-node, the following ASCII and structured architectural diagrams detail the system design.
