Efficient Fog Computation for Marine Data Feedback to Space-Ground Integrated Access Networks

In integrated space-ground networks, a fog node which collects data may feed data to the data center via any available access networks such as automatic identification system (AIS) and satellite network. Considering those maritime networks usually have limited communication capacity, we use fog-computation for data compression before the feedback. Given an available access network with constrained communication resources, we propose an online scheduling scheme to efficiently compress data for guaranteed quality-of-service (QoS) data feedback. This scheme is independent to accurate modeling of communication channel and network. In addition, the scheme is suitable for any space-ground integrated access networks. These merits make it be easily implemented on marine fog nodes. Results show that the proposed scheme can efficiently compress data and feed them back while guarantee QoS constraints of different applications.
