Statistical Performance Evaluation of UDP Communication in IoT Environments: A Comparative Study of Small-Scale vs Large-Scale Packet Transmission under Latency Variations

With the rapid expansion of the Internet of Things (IoT), reliable and efficient data transmission has become a critical requirement for large-scale heterogeneous deployments. This paper presents a comprehensive simulation-based performance analysis of three widely adopted IoT transport protocols—UDP, CoAP, and MQTT—under Rayleigh fading channel conditions using a MATLAB-based framework. The study evaluates the transmission of 100 and 1000 data packets under three distinct latency regimes: low, medium, and high. Key performance metrics include end-to-end delay, jitter, packet loss ratio, and throughput. A novel Adaptive Exponential Moving Average (EMA) jitter buffer algorithm is proposed, achieving 57–65% jitter reduction across all tested scenarios. Protocol comparison reveals that UDP achieves the lowest average delay (20 ms under low conditions), while MQTT incurs the highest overhead (+20 ms) due to broker relay. Monte Carlo statistical analysis with 500 simulation runs confirms result convergence within 0.5 ms between 100-packet and 1000-packet scales. The findings provide practical design guidelines for IoT protocol selection and establish a reproducible benchmark for evaluating transport-layer behavior in constrained wireless ad hoc networks.

Developing a Model to Improve the Efficiency of Maintenance Management for Service Buildings Using BIM and Power BI: A Case Study

Maintenance management has a major role in maintaining service buildings and improving their performance. Therefore, in this research, building information modeling (BIM) was applied to one of the university buildings to obtain detailed and accurate information about the building’s components and link maintenance data to each element of the building through the capabilities and flexibility of the Revit program, which is reflected in the It is evident in the ability to add parameters to the elements and thus sort the maintenance data according to the elements of the building and model it to turn into information that can be extracted, analyzed and explored for the implicit knowledge in it through business intelligence techniques, to understand it and make appropriate decisions, which is reflected in the accuracy of maintenance work and achieving the best quality of service at the lowest cost. . Relying on the descriptive and analytical approach, by describing the reality of maintenance management in the Maintenance Department, describing the architectural maintenance work that took place within a period of 5 years (2019-2023), and conducting an accurate description of all the elements of the building to create a BIM model for the building of the College of Mechanical and Electrical Engineering. Then link the maintenance data with the operational data of the model by entering the maintenance parameters on the architectural elements of the building (doors - walls - windows - false ceilings - floors) and taking advantage of what Revit technology provides in creating tables specific to the building, and exporting them to Excel and then to the Power program. Bi, which provides the ability to analyze data, identify the most important maintenance problems and the maintenance cost for each item, determine the proportions of implemented and non-implemented items, determine the reasons for non-implementation, and measure the performance of workshops and specialists.

Design of an Iterative Q Learning Model for Multistage Classification of Diabetic Retinopathy & Glaucoma

This study addresses the escalating prevalence of diabetic retinopathy (DR) and glaucoma, major global causes of vision impairment. To improve diagnostic accuracy and classification speed, we propose an innovative iterative Q Learning model integrated with Fuzzy C Means clustering. Traditional diagnostic frameworks often struggle with accuracy and delay in disease stage classification, particularly in discerning complex features like exudates and veins. Our model overcomes these challenges by combining Fuzzy C Means with Q Learning, enhancing precision in identifying key retinal components. The core of our approach is a custom-designed 45- layer 2D Convolutional Neural Network (CNN) optimized for nuanced detection of DR and glaucoma stages. Performance on IDRID and SMDG-19 datasets and their samples demonstrates a 10.9% higher precision, 8.5% increased overall accuracy, 8.3% improved recall, 10.4% higher Area under the Curve (AUC), 5.9% enhanced specificity, and a 2.9% reduction in delay compared to existing methods. This model has transformative potential in revolutionizing DR and glaucoma diagnostics, paving the way for timely medical interventions and potentially reducing vision loss. The integration of advanced machine learning with medical imaging sets a precedent for future research in ophthalmology and beyond in clinical scenarios.

Design, Simulation and Analysis of Multi-Dimensional Multiple Access (MDMA) Schemes Using MATLAB for Quality of Service (QoS) Enhancement

To provide better Quality of Service (QoS), which is expected in contemporary 6G wireless networks. We project a MDMA scheme to fulfill UE-specific QoS needs with the aid of multi-dimensional radio resource cost. This method can be successfully called Multi-Dimensional Radio Resource Allocation (MDRA). Specifically, the planned scheme incorporates two novel aspects: for each UE, the choice of user-specific non-orthogonal multiple approach mode whose cost is determined by UE-specific non-orthogonal interference cancellation; and allocating multiple dimensional radio resources for co-existing UEs in dynamic network environment. To reduce the costs of using UE-specific resources, the BS mounts UEs with diverse multi-domain resources. Specific to each UE coalition by taking into consideration restrictions such as the availability of resources, the perceived quality of those resources, and the possibility for use. Every UE that is a part of the coalition has access to the radio resources that it needs, which helps to lower the costs of use while preventing resource-sharing disputes with the other nodes in the coalition. Furthermore, the allocation of multi-dimensional radio resources among co-existing user equipment makes it possible to solve the issue of maximizing the sum of cost-conscious utility. This is done to fulfil UE-specific quality of service needs as well as varied resource circumstances on the user equipment side. The gradient convexity with low complexity approximation and the Lagrange double decomposition approach are used in the development of the solution to this NP-hard issue. The efficacy of the system that we have presented is shown via the use of numerical simulations and a comparison of its performance with that of other methods.

On The Minimal Sets and Stability Conditions For Compact Sets In I(X)-spaces

The set of all isometries on a metric space X with the usual composition of functions form a group and it is called the group of isometries and is denoted by I(X). In this paper we study the generalization of the concepts of minimal sets, stability and attraction, from dynamic system into the topological transformation group (I(X),X).We find that the collection of all minimal sets of I(X)-space is the collection of all the closures of orbits of X and we found some useful results about stability and attraction and we fixed the relationship among it's kinds.

On Some Results About P - Lindelöf Spaces

In this work, we study p-Lindelöf spaces, a concept which is "stronger" than Lindelöf spaces. Every p-compact space is proven to be p-Lindelöf space, so the concept of p-Lindelöf is a generalization of the concept of p-compact. Most of the theorems which are valid for p-compact spaces will be also valid for p-Lindelöf spaces, (with a slight modification). We also study local p-Lindelöf spaces with many related theorems and examples.
