Stochastic Buffer-Aided Relay-Assisted MEC

This paper studies buffer-aided relay-assisted Mobile Edge Computing (MEC) architecture as the fundamental system in hierarchical multi-hop MEC. We propose a stochastic offloading scheme where a buffer-aided relay, equipped with a computing server, randomly decides to process the tasks of a source node by its own server, or to forward them to the server of the next node in the hierarchy. We analyze the proposed scheme and formulate a problem to...
