Abstract

With the advent in cloud technologies a parallel rise has been seen on the use of IOT infrastructure. As part of this Edge/Fog computing paradigm we see devices like smartwatches, mobile phones and other devices constituting it. For issues like computational power, limited storage, limited power/battery and non scalable architecture are already known to be a part as deficiency in resource department of in Edge computing. One viable solution to tackle this resource problem is to offload the workload from edge/mobile to either a fog/cloudlet server or to a centralised main cloud server. So running workloads locally will drain the limited resources, and entirely executing workloads on the cloud which is called cyberforaging and has a drawback that it will incur communication cost and will have a delay as well. So a balanced approach among these two is needed. I am proposing a Novel approach for this yet open challenge of choosing what to offload to cloud and in what order for different conditions faced by a resource constraint edge/mobile device having different priority workloads. So, choices will be either to face delay by offloading to a cloud and incur communication costs compromising QoS of application or to execute this workloads on the edge/mobile devices which is power/energy(resource) constrained device. Will use a priority based queueing scheme for marking workloads with priority. Using EdgeCloudSim as a simulator to reproduce environment to prove the novel approach. After experimentation I got results which shows a lower failure percentages of high priority applications, thus increasing there QoS and also dealt with the trade off dilemma.
