Abstract:
In Vehicular networks, applications commonly have location-dependent requirements. Services such as those transit-related may require that vehicles obtain content from specific regions. In these cases, unless previously cached by another node, requests must necessarily be provided by nodes near the physical location for which information is requested. This asymmetry in content availability poses a significant challenge to content provisioning. In this work, we propose a caching policy based on collaborative observation of locality in request frequency, designed to allow vehicles to preemptively distribute and store in a reserved portion of the cache based on the cooperative observation of requests with provider-based location correlation. The proposed solution can significantly improve content delivery, with over 30% improvement in overall content delivery when compared to scenarios where Provider-based Location Correlation (PLC) is observed but no targeted policy is employed.
