Cooperative Computation Offloading in FiWi‐Enhanced Mobile Networks

In this chapter, the authors focus on the quality of experience (QoE) of mobile users (MUs) measured by the average response time that can be influenced by the queueing/processing and transmission delay components, including those between MUs and multi‐access edge computing (MEC)servers and also between MEC servers and the remote cloud. They examine the performance gains obtained by cooperative computation offloading in MEC‐enabled fiber‐wireless (FiWi) enhanced Heterogenous Networks (HetNets), which relies on not only the computational capabilities of edge/cloud servers but also the limited local computing resources at the device side. The authors aim to design a two‐tier MEC‐enabled FiWi enhanced HetNet architecture, where the mobile devices as well as the edge servers cooperatively offload their computation tasks toward achieving a reduced average response time. They present their analytical framework for estimating the energy‐delay performance of the proposed cooperative task offloading scheme.
