Title
Caching and forwarding assistance for vehicular information services with mobile requesters
Abstract
Smart vehicles have been capturing increasing attention as major providers of ubiquitous information services. In this paper, we propose a solution to enable expedited and cost-effective access of road information for vehicles as information requesters. The proposed caching-assisted data delivery with mobile requesters (CADD-MR) scheme employs caching on the data delivery path for handling later interests in similar data. CADD-MR depends on the use of light-weight road caching spots (RCSs) deployed at intersections for caching and heading-aware forwarding, and on vehicles as data carriers. To support vehicles as mobile information requesters, CADD-MR makes use of the RCSs for keeping track of the mobility registry of the requesting vehicles to ensure that data replies reach their corresponding mobile destinations, as long as they are still not expired. Performance evaluation of CADD-MR demonstrates significant improvements in the access cost, delay, and delivery ratio compared to a scheme that does not use RCSs.
