A Review: The Internet of Things Using Fog ComputingIRJET Journal
Fog computing is a new computing paradigm that processes data and analytics at the edge of the network, rather than sending all data to a centralized cloud. This helps address issues with the cloud-based Internet of Things (IoT) model, such as high latency, bandwidth constraints, location awareness, and mobility. Fog computing brings computing resources closer to IoT devices and end users by using edge devices like routers, switches, and access points as "fog nodes" that can perform analytics and decision making. This allows time-sensitive IoT applications to function more efficiently. Fog computing also helps optimize resource usage by balancing processing between the edge and cloud.
The document defines cloud computing according to the National Institute of Standards and Technology (NIST). It identifies five essential characteristics of cloud computing (on-demand self-service, broad network access, resource pooling, rapid elasticity, and measured service). It also outlines three service models (Software as a Service, Platform as a Service, and Infrastructure as a Service) and four deployment models (private cloud, community cloud, public cloud, and hybrid cloud). The purpose is to provide a baseline definition and taxonomy to facilitate comparisons of cloud services and deployment strategies.

This document discusses a proposed smart transportation system that integrates Internet of Things (IoT), big data approaches, and cloud computing. The system would use sensors to capture transportation data from vehicles and infrastructure in real-time. This IoT data would generate large volumes of diverse data (the "4Vs" of big data) that could be stored and analyzed in the cloud to provide insights for transportation planning and management. The proposed system aims to combine these technologies to develop intelligent transportation system cloud services to help optimize traffic flow and infrastructure usage.
Effect of Mixing and Compaction Temperatures on the Indirect Tensile Strength...IRJET Journal
This document proposes an e-toll payment system using Azure cloud that automates toll payments. A mobile app allows users to pay tolls digitally via wallet, credit/debit cards, or banking. Successful payments are recorded on Azure cloud along with the vehicle's RFID tag ID. At toll gates, RFID readers scan tags and check the cloud to see if payment was made. If so, the gate opens, streamlining the toll process and reducing congestion. The system aims to provide a more convenient cashless toll payment alternative compared to existing smart card or queue-based systems.

Integrated Analytics for IIoT Predictive Maintenance using IoT Big Data Cloud...Hong-Linh Truong
For predictive maintenance of equipment with In-
dustrial Internet of Things (IIoT) technologies, existing IoT Cloud
systems provide strong monitoring and data analysis capabilities
for detecting and predicting status of equipment. However, we
need to support complex interactions among different software
components and human activities to provide an integrated analyt-
ics, as software algorithms alone cannot deal with the complexity
and scale of data collection and analysis and the diversity of
equipment, due to the difficulties of capturing and modeling
uncertainties and domain knowledge in predictive maintenance.
In this paper, we describe how we design and augment complex
IoT big data cloud systems for integrated analytics of IIoT
predictive maintenance. Our approach is to identify various
complex interactions for solving system incidents together with
relevant critical analytics results about equipment. We incorpo-
rate humans into various parts of complex IoT Cloud systems
to enable situational data collection, services management, and
data analytics. We leverage serverless functions, cloud services,
and domain knowledge to support dynamic interactions between
human and software for maintaining equipment. We use a real-
world maintenance of Base Transceiver Stations to illustrate our
engineering approach which we have prototyped with state-of-
the art cloud and IoT technologies, such as Apache Nifi, Hadoop,
Spark and Google Cloud Functions.

A review on orchestration distributed systems for IoT smart services in fog c...IJECEIAES
This paper provides a review of orchestration distributed systems for IoT smart services in fog computing. The cloud infrastructure alone cannot handle the flow of information with the abundance of data, devices and interactions. Thus, fog computing becomes a new paradigm to overcome the problem. One of the first challenges was to build the orchestration systems to activate the clouds and to execute tasks throughout the whole system that has to be considered to the situation in the large scale of geographical distance, heterogeneity and low latency to support the limitation of cloud computing. Some problems exist for orchestration distributed in fog computing are to fulfil with high reliability and low-delay requirements in the IoT applications system and to form a larger computer network like a fog network, at different geographic sites. This paper reviewed approximately 68 articles on orchestration distributed system for fog computing. The result shows the orchestration distribute system and some of the evaluation criteria for fog computing that have been compared in terms of Borg, Kubernetes, Swarm, Mesos, Aurora, heterogeneity, QoS management, scalability, mobility, federation, and interoperability. The significance of this study is to support the researcher in developing orchestration distributed systems for IoT smart services in fog computing focus on IR4.0 national agenda.
1) Predictive analytics using IoT data faces unique challenges due to issues with data quality from IoT sources. The "data-insight gap" is a challenge for obtaining accurate predictions from incomplete and inconsistent IoT data.
2) Current IoT+predictive architectures are cloud-centric but future architectures will move more of the processing and analytics to the edge to improve responsiveness and deal with high data volumes.
3) Cleaning and preparing IoT data for machine learning algorithms is a major challenge since most advanced techniques require large volumes of consistent, high-quality data but IoT data is often incomplete and inconsistent. A two-tiered approach using ML for both data cleaning and predictive modeling may help

MULTI-ACCESS EDGE COMPUTING ARCHITECTURE AND SMART AGRICULTURE APPLICATION IN...ijmnct
The Ubiquitous Power Internet of Things (UPIoT) is a deep integration of the interconnected power
network and communication network, enabling full perception of the system status and business operations
for power production, transmission, and consumption. To address the challenges of real-time perception,
rapid response, and privacy protection, UPIoT can benefit from the use of edge computing technology.
Edge computing is a new and innovative computing architecture that enables quick and efficient
processing of data close to the source, bypassing network latency and bandwidth issues. By shifting
computing power to the edge of the network, edge computing reduces the strain on cloud computing
centers and decreases input response time for users. However, access latency can still be a bottleneck,
which may overshadow the benefits of edge computing, particularly for data-intensive services. While edge
computing offers promising solutions for the IoT network, there are still some issues to address, such as
security, incomplete data, and investment and maintenance costs. In this paper, researcher conducts a
comprehensive survey of edge computing and how edge device placement can improve performance in IoT
networks. The paper includes a comparative use case of smart agriculture edge computing
implementations and discusses the various challenges faced in implementing edge computing in the UPIoT
context. The results also aim to inspire new edge-based IoT security designs by providing a complete
review of IoT security solutions at the edge layer in UPIoT

Lightweight IoT middleware for rapid application developmentTELKOMNIKA JOURNAL
Sensors connected to the cloud services equipped with data analytics has created a plethora of new type of applications ranging from personal to an industrial level forming to what is known today as Internet of Things (IoT). IoT-based system follows a pattern of data collection, data analytics, automation, and system improvement recommendations. However, most applications would have its own unique requirements in terms of the type of the smart devices, communication technologies as well as its application provisioning service. In order to enable an IoT-based system, various services are commercially available that provide services such as backend-as-a-service (BaaS) and software-as-a-service (SaaS) hosted in the cloud. This, in turn, raises the issues of security and privacy. However there is no plug-and-play IoT middleware framework that could be deployed out of the box for on-premise server. This paper aims at providing a lightweight IoT middleware that can be used to enable IoT applications owned by the individuals or organizations that effectively securing the data on-premise or in remote server. Specifically, the middleware with a standardized application programming interface (API) that could adapt to the application requirements through high level abstraction and interacts with the application service provider is proposed. Each API endpoint would be secured using Access Control List (ACL) and easily integratable with any other modules to ensure the scalability of the system as well as easing system deployment. In addition, this middleware could be deployed in a distributed manner and coordinate among themselves to fulfil the application requirements. A middleware is presented in this paper with GET and POST requests that are lightweight in size with a footprint of less than 1 KB and a round trip time of less than 1 second to facilitate rapid application development by individuals or organizations for securing IoT resources.

F2CDM: Internet of Things for Healthcare Network Based Fog-to-Cloud and Data-...Istabraq M. Al-Joboury
Internet of Things (IoT) evolves very rapidly over time, since everything such as sensors/actuators linked together from around the world with use of evolution of ubiquitous computing through the Internet. These devices have a unique IP address in order to communicate with each other and transmit data with features of wireless technologies. Fog computing or so called edge computing brings all Cloud features to embedded devices at edge network and adds more features to servers like pre-store data of Cloud, fast response, and generate overhasty users reporting. Fog mediates between Cloud and IoT devices and thus enables new types of computing and services. The future applications take the advantage of combing the two concepts Fog and Cloud in order to provide low delay Fog-based and high capacity of storage Cloud-based. This paper proposes an IoT architecture for healthcare network based on Fog to Cloud and Data in Motion (F2CDM). The proposed architecture is designed and implemented over three sites: Site 1 contains the embedded devices layer, Site 2 consists of the Fog network layer, while Site 3 consists of the Cloud network. The Fog layer is represented by a middleware server in Al-Nahrain University with temporary storage such that the data lives inside for 30 min. During this time, the selection of up-normality in behavior is send to the Cloud while the rest of the data is wiped out. On the other hand, the Cloud stores all the incoming data from Fog permanently. The F2CDM works using Message Queue Telemetry Transport (MQTT) for fast response. The results show that all data can be monitored from the Fog in real time while the critical data can be monitored from Cloud. In addition, the response time is evaluated using traffic generator called Tsung. It has been found that the proposed architecture reduces traffic on Cloud network and provides better data analysis.

TIME DIVISION MULTIPLEXING TECHNIQUE FOR COMMUNICATION SYSTEMHODECEDSIET
Time Division Multiplexing (TDM) is a method of transmitting multiple signals over a single communication channel by dividing the signal into many segments, each having a very short duration of time. These time slots are then allocated to different data streams, allowing multiple signals to share the same transmission medium efficiently. TDM is widely used in telecommunications and data communication systems.
### How TDM Works
1. **Time Slots Allocation**: The core principle of TDM is to assign distinct time slots to each signal. During each time slot, the respective signal is transmitted, and then the process repeats cyclically. For example, if there are four signals to be transmitted, the TDM cycle will divide time into four slots, each assigned to one signal.
2. **Synchronization**: Synchronization is crucial in TDM systems to ensure that the signals are correctly aligned with their respective time slots. Both the transmitter and receiver must be synchronized to avoid any overlap or loss of data. This synchronization is typically maintained by a clock signal that ensures time slots are accurately aligned.
3. **Frame Structure**: TDM data is organized into frames, where each frame consists of a set of time slots. Each frame is repeated at regular intervals, ensuring continuous transmission of data streams. The frame structure helps in managing the data streams and maintaining the synchronization between the transmitter and receiver.
4. **Multiplexer and Demultiplexer**: At the transmitting end, a multiplexer combines multiple input signals into a single composite signal by assigning each signal to a specific time slot. At the receiving end, a demultiplexer separates the composite signal back into individual signals based on their respective time slots.
### Types of TDM
1. **Synchronous TDM**: In synchronous TDM, time slots are pre-assigned to each signal, regardless of whether the signal has data to transmit or not. This can lead to inefficiencies if some time slots remain empty due to the absence of data.
2. **Asynchronous TDM (or Statistical TDM)**: Asynchronous TDM addresses the inefficiencies of synchronous TDM by allocating time slots dynamically based on the presence of data. Time slots are assigned only when there is data to transmit, which optimizes the use of the communication channel.
### Applications of TDM
- **Telecommunications**: TDM is extensively used in telecommunication systems, such as in T1 and E1 lines, where multiple telephone calls are transmitted over a single line by assigning each call to a specific time slot.
- **Digital Audio and Video Broadcasting**: TDM is used in broadcasting systems to transmit multiple audio or video streams over a single channel, ensuring efficient use of bandwidth.
- **Computer Networks**: TDM is used in network protocols and systems to manage the transmission of data from multiple sources over a single network medium.
### Advantages of TDM
