MEC support for C-V2X System Architecture

2019 IEEE 19th International Conference on Communication Technology (ICCT), 2019
This paper proposed an original four-layer architecture of MEC support for C-V2X system, summarizing the participants in C-V2X scenarios and the logical relationship between the participants. Three novel APIs are designed to meet the requirement of C-V2X end-to-end service under the MEC support for C-V2X system architecture.

C-V2X Greedy Cooperative Caching and Response Algorithm

2021 IEEE International Conference on Electronic Technology, Communication and Information (ICETCI), 2021
Greedy Cooperative Caching and Response Algorithm (GCCR) is proposed to relieve the communication load of base station as edge Caching source in C-V2X and improve the efficiency of data transmission. Under the constraint of node topological relationship, the greedy flooding cache node allocation order is adopted to increase the complementary ...
