Mobility of Internet of Things and Fog Computing: Serious Concerns and Future Directions

Abstract

IoT devised the modern world of technology into a world where different objects are joining the global network, exchanging, storing and processing the data using different surrounding environments and actively intercede. Enormous number of services can be visualized and put into reality by using the basic concepts of IoT. Since IoT devices are resource constrained, the concept of edge computing also termed as fog computing was proposed to assist IoT devices in handling and delivery information. The centralized cloud is not replaced by fog but enhances its functionality, accessibility and reliability in many means by distributing its principles and technologies through the CoT continuation, specifically at edge of network. The nearness of the fog and IoT nodes enables many distinctive features that should be available and protected always even during the movement of IoT devices through different places. This article discusses the main challenges by analyzing the concept of providing mobility support in a fog environment.
