MEC (Mobile Edge Computing) is a network technology that enables the deployment of computing

and storage resources at the edge of the network, closer to the end-users. This can significantly

reduce the latency for various applications, such as IoT, AR/VR and IoV. By moving the computing and

storage resources closer to the end-users, the data can be processed and stored closer to the source,

reducing the time and distance that the data needs to travel. This can reduce the overall latency and

improve the user experience.

According to the official GSMA white paper on 5G and IoV, MEC can reduce latency by bringing

computing resources closer to the edges of the network. This can be particularly beneficial for IoV

applications, which require low latency and high reliability. Additionally, NFV (Network Function

Virtualization), Massive MIMO (Multiple Input Multiple Output) and SDN (Software Defined

Networking) can also be used to improve performance and reduce latency in 5G networks.
