However, either of them requires V2X communications to provide secure, reliable, and efficient handover authentication with low computation overheads. It becomes extremely challenging when vehicles move with frequent handovers. In this paper, a lightweight handover authentication scheme is proposed for 5G-based V2X communications. Specifically, each vehicle can initially acquire a temporary encrypted identity from a network function virtualization (NFV)-manager in its home public land mobile network (PLMN). This encrypted identity is used to authenticate the vehicle to the new PLMN when a handover occurs. By comparing with two previous schemes, simulation results show that the proposed scheme achieves over 50% less computation overhead than those achieved in both of them, while does not affected the overall network handover latency much. Additionally, the prop...

The main contribution of this paper is to model and propose a novel scheduling scheme for LTE networks and to compare its performance with the performances of both the Best-CQI and RR Uplink schedulers. The Best-CQI scheduler is characterized by high data rates at cell level, but poor fairness. On the other hand, the round robin (RR) scheduler is characterized by low data rates at cell level, but good fairness. The main goal of our proposed scheme is to process these two conflicts terms in a better way. Performance modeling results presented in the paper show that the newly proposed scheduling scheme allows fair distribution of available LTE resources while at the same time keeps the system's capacity utilization as good as possible.
