A New ICN routing selecting algorithm based on Link Expiration Time of VANET under the highway environment

摘要

Combining VANET with ICN (Information Centric Network), this paper proposes a new FIB (Forwarding Information Base) selecting algorithm-ECRMLET (Efficient Content Routing Model Based on Link Expiration Time). To build stable routings and reduce network traffic, our ECRMLET has the following designs: 1) we modify the structure of PIT (Pending Interest Table) by adding two domains: receive time and tolerance time; 2) we introduce the algorithm of LET (Link Expiration Time) to help with the content routing selection in FIB; 3) ECRMLET also gets the link availability probability to be auxiliary information for our algorithm.
