Task Scheduling in Fog Computing: Parameters, Simulators and Open Challenges

As Internet of Things (IoT) is evolving very rapidly which is producing massive amount of data and normally all this data is shifted towards the cloud for further execution which puts burden on the cloud and doesn’t fulfill QoS requirements. In order to overcome this problem computing facility were extended towards the edge of the network and the concept is known as Fog computing. Due to heterogeneity of fog nodes and dynamic user requirements, task scheduling in fog computing has become the big challenge. This paper covers the literature review which classify the task scheduling algorithm in terms of approaches, it highlights the parameters mostly used, it also covers the analysis among the available simulation tools and highlight the open issues and challenges which will help the researchers for their problem formulation.
