Low-latency edge cooperation caching based on base station cooperation in SDN based MEC

作者:

Highlights:

• A low-latency edge caching method based on multi-base station cooperation is proposed.

• A migration method based on balanced overhead of communication and migration is proposed.

• The problem of minimizing latency is transformed into a problem of maximizing cache reward.

• The reinforcement learning method is used to obtain service migration scheme.

• The performances of the proposed algorithms are evaluated through experiments.
