Smart devices in various application areas are becoming increasingly prevalent for efficient handling of multiple critical activities. One such area of interest is high-security militarized environments. Due to military zones’ harsh and unpredictable nature monitoring devices deployed in such environments must operate without power interruption for extended time periods. Therefore it is essential to choose an appropriate application design for operating these “things” in the internet of things (IoT) environment such that energy can be conserved throughout the operating span of an application. This paper presents two application modules and analyzes their performance in terms of energy conservation considering a military-based IoT-Fog architecture. The two modules are: A sequential application module and a master-worker application module. Experimental results show that the master-worker module incurs lower energy consumption and communication overhead than the sequential application module. Significantly the master-worker module exhibits a lower delay in tuple execution by almost four milliseconds while also accounting for lower simulation time and higher network utilization. The module achieves significant savings in energy consumption making it more effective in handling smart devices. © 2024 Elsevier B.V. All rights reserved.

As cloud computing is gaining more recognition as a public utility which gives the client room to focus on his work without focusing on installation and maintenance of other important devices, as they are installed and maintained by the cloud service providers. Cloud computing is meant to be scalable, and enhance the quality of service (QoS), cost effective and also simplified user interface so that the customer can appreciate the idea behind cloud computing. In dealing with resource allocation, the client's request has to be executed through various stages in case there are queue of requests waiting to be served in each stage. Therefore, queuing methods are required to solve this kind of situation. In this thesis, we focused on mathematical formulation using queuing system technique to show how throughput and time delay, level of occupancy or utilization of a system and the response time may vary between a single server system and a virtualized multiple server system in a cloud-computing environment. Virtualization technology is employed in the field of cloud computing in order to complement the activities of physical server system such as in the case of load balancing which aim at distributing load to a set of virtual resource using various balancing techniques, in this thesis max-min algorithm is employed to investigate the behavior of the virtual machine when executing set of tasks in terms of efficiency.
