Vehicle to Infrastructure Communications Design in Urban Hyperfractals

This study exploits our innovative model called "hyperfractal" that captures the self-similarity of the urban vehicular networks as well as incorporating road-side infrastructure with its own self-similarity. The goal is to provide understanding of achievable trade-offs in operating the road-side units under the constraint of minimum routing path delay while maintaining a reasonably balanced load. The models and results are supported by simulations with different city hyperfractal dimensions in two different routing scenarios: nearest neighbor routing with no collision and minimum delay routing model assuming slotted Aloha and signal to interference ratio (SIR) capture condition, power-path loss and Rayleigh fading.
