摘要：

Increased Caching Capability is one of the main benefits of Information-Centric Networking and a necessity for highly mobile ad-hoc networks such as VANETs. Hence, it is crucial to efficiently store items to improve resource utilization, increasing cache efficiency, reducing network load. In this paper, we propose a cache content insertion policy, UG-Cache, for ICN-VANETs. In UG-Cache, cache insertion decisions are made based on recommendations from content sender dependent on request frequency and cache distance. Numerical results denote the benefits of increased control over cache variety via application of UG-Cache. Simulation results reveal increased delivery rates and reduced average hop count of content delivery of UG-Cache over other schemes. UG-Cache also achieves higher cache hit ratio than other on-demand caching strategies.
