Review on QoS Aware Resource Management in Fog Computing Environment

摘要: The ever-increasing demand for computing power and the high penetration of Internet Things(IoT) in our daily life interactions undoubtedly enhance quality life. To fulfill heterogeneous these IoT applications Quality service(QoS) is an important performance measurement metric that must be considered. traditional paradigm not effective to address latency sensitive generated through devices. overcome limitations a novel Fog emerges as viable solution provide cloudlike services. However moving computation, networking, storage resources edge network near source do guarantee solve all challenges. Due limited capacities fog nodes, optimal distribution key overall paradigm. available infrastructure are constrained so there critical need optimize layer handle allocate efficiently different network. manage we study resource management issues, objectives, approaches. Different authors classify policy into methods like service placement, scheduling, allocation, provisioning adopted heuristic meta-heuristic strategies layers communication, storage, data, energy from end-user. In this paper discuss functionality importance orchestration node generic three-tier architecture primarily designed efficient workload number virtual machines required, etc. execute dynamic environment. Also, introduce some challenges included order better QoS clients.
