Abstract
This paper aims to propose a new fog cloud architecture that performs a joint energy-efficient task assignment (JEETA). The proposed JEETA architecture utilizes the dynamic application-partitioning algorithm (DAPTS), a novel algorithm that efficiently decides and switches the task to be offloaded or not in heterogeneous environments with minimal energy consumption. The proposed scheme outperforms baseline approaches such as MAUI, Think Air and Clone Cloud in many performance aspects. Results show that for the execution of 1000 Tasks on fog, mobile offloaded nodes, JEETA consumes the leas, i.e., 23% of the total energy whereas other baseline approaches consume in between 50%–100% of the total energy. Results are validated via real test-bed experiments and trice are driven efficient simulations.
Highlights
Applications of the Internet of things (IoT) such as e-healthcare, e-vehicle, e-commerce, etc. have been growing progressively since the last decade [1]
This paper proposes new fog cloud architecture (FCA), which efficiently manages the data flow and data processing mechanism for all IoT applications without losing any generosity of the system
To evaluate the performance of the proposed method joint energy efficient task assignment (JEETA), this paper presents an implementation of three baseline approaches in the mobile cloud computing environment
Summary
Applications of the Internet of things (IoT) such as e-healthcare, e-vehicle, e-commerce, etc. have been growing progressively since the last decade [1]. Fog computing is an extension of cloud computing. In the FC network, the fog nodes are servers, which are placed at the edge of the Internet [6,7]. Computation offloading is a method used to transfer resources intensive computation tasks of an application to the external server for processing [10,11]. Resource-constrained devices (i.e., storage, computation power, battery) only process lightweight tasks of an application, wherein, computation intensive tasks of an application are more likely to be offloaded to the FC for processing [13]
