Abstract- The increasing adoption of the Internet of Things (IoT) has revolutionized various aspects of our lives, enabling the automation of daily tasks without human intervention. This exciting technology has tremendous potential for simplifying our lives and creating opportunities for new applications. The unpredictable nature of network traffic, varied traffic patterns, and resource restrictions of IoT devices make it difficult to meet the varied Quality of Service (QoS) requirements for various IoT applications. To address this challenge, academia has focused on developing QoS provisioning mechanisms tailored to specific IoT applications.

Driving IoT Success in Cloud Computing Through Operating Systems

Ali Haider, M. J. Arshad

Department of Computer Science, University of Engineering and Tecnology Lahore, Pakistan

Abstract- As twenty-first-century innovations, the Internet of Things (IoT) and Cloud Computing (CC) have fundamentally reshaped the Information and Communication Technology (ICT) landscape. Among these, IoT, an avant-garde concept, promises to revolutionize our interaction with everyday objects by transforming them into intelligent virtual entities. This transformation is achieved through the interconnection of devices - from lights, TVs, door locks, to microwaves and coffee makers - via the internet, software applications, sensors, and actuators. In parallel, Cloud Computing, widely recognized for powering large-scale and data intensive applications, employs a distributed system to facilitate interaction among diverse computing devices and information sources. The significance of Cloud Computing extends beyond the provision of on-demand computing power; it fuels innovation by enabling more efficient and effective utilization of this capacity. In this discussion, we primarily focus on IoT while acknowledging the complementary role of Cloud Computing. We will introduce the technologies underpinning IoT and Cloud Computing, dissect the structure, flow, and function of their systems, and underscore the integral role of the operating system as a unifying platform. This emphasis on IoT is crucial, given its potential to transform our interaction with real-world objects and its dependency on sophisticated systems and infrastructures.

Abstract- Soil acidity becomes a serious threat to crop production in most highlands of Ethiopia particularly in Western parts of Oromia. Frequent tillage, removal of crop residues and mono-cropping and heavy rainfall contribute to soil acidification by leaching of cations. Agricultural limestone raises soil pH and reduces solubility of potentially toxic elements such as hydrogen, aluminum (Al 3+) and manganese (Mn) at optimum nutrient uptake by crops. In an effort to alleviate the problems associated with soil acidity, a motorized agricultural limestone crusher was designed and fabricated. The prototype of limestone crusher machine has a feed table, hammer plate, concave sieve, discharge chute, and supporting frame.

Keywords- Hammer Mill, Limestone, Particles Size, Problems and Crushing.

A Comparative Analysis of Wireless Communications in Satellite, WLL, Ad-Hoc, 4G and IoT Sensor Networks

Aizaz Ahmad, Waseem Elahi

Department of Computer Science, University of Engineering & Technology Lahore, PK 54890, Pakistan

Abstract- Wireless communication technology has become increasingly popular over the years due to its ease of deployment, flexibility, and cost-effectiveness. Satellite communication is widely used for long-distance communication, and it enables global coverage. In contrast, Wireless Local Loop (WLL) is used for short-range communication in a limited geographical area. 4G technology offers high-speed data transfer and improved network coverage. Ad-hoc networks are self-configuring networks, which enable communication between devices without the need for a centralized infrastructure. Finally, IoT sensor networks involve a huge number of sensors that collect data and communicate with each other to provide various services. Each of these networks has unique communication challenges and requirements that must be addressed. For example, satellite communication must deal with long propagation delays, while WLL requires low-power, low-latency communication. Ad-hoc networks must handle high mobility and dynamic topology, while IoT sensor networks must ensure energy efficiency and scalability. This research paper has the main objective to provide an overview of wireless communication technologies in one place and the unique challenges they are facing nowadays. It will be useful for researchers, engineers, and practitioners interested in the field of wireless communication technologies and its applications in different network scenarios.

Keywords- Wireless Communication, Wireless Local Loop (WLL), 4G Network, IoT Sensor Network, Ad-Hoc Network and Satellite Communication.

Abstract- The growth of IoT applications and connected smart devices has made routing a challenging concept. To address this, the IPv6 Routing Protocol for Low-power and Lossy Networks (RPL) was standardized for IoT networks. However, RPL was designed for stationary IoT applications and has difficulty adapting to the dynamic fluctuations of mobile applications. While several studies have attempted to adjust RPL for mobile IoT applications, a standardized version of this protocol is still in high demand. This research presents a comprehensive study on the impact of various mobility models on the performance of a mobility aware RPL to facilitate this process. A performance evaluation is conducted using IoT simulation tools to compare the performance of the network and its IoT devices under different mobility models from several perspectives. The results of this research will aid researchers in both academia and industry in designing and implementing application-specific and standard versions of RPL suitable for mobile IoT applications.

Keywords- Internet of Things, Mobility Models, Simulation, RPL, Routing Protocols, Performance Evaluation and Energy Consumption.
