Abstract
The new computing paradigm is the fog computing gaining its popularity as a distributed computing, provides services like cloud-computing nearer to the end devices and for latency sensitive application. By offering cloud-like computing and storage capabilities at a lower latency and using less bandwidth, it improves the computational capabilities of mobile nodes and IoT (Internet of Things) devices. Fog computing also has the capacity to provide node mobility, context awareness, dependability, and scalability. Fog computing is used to offload tasks from applications running on end devices due to its many advantages. This enables apps that use the capabilities of fog nodes to run more quickly. Due to the fog environment’s dynamic nature, task offloading is considered to be a challenging problem in fog center. This paper proposes a SDN-based QoS-aware task offloading technique using golden jackel, a unique optimisation algorithm inspired by nature for scheduling tasks to the available Virtual machines (VMs) in the fog layer.
