Scheduling for interference mitigation using enhanced intercell interference ...eSAT Journals
Abstract Deployment of low power base station (pico) in macro cell is a key for providing high data rates. Cell range expansion is one of the features of LTE-advanced where low power base station in a heterogeneous network can increase their coverage area and neighboring cells can offload users to low power base station to reduce overload in macro cell. This presents a very challenging multi-user communication problem. Co-channel deployed Het-Net will experience interference between pico and macro. The main challenge of pico cells embedded into a macro cell is to let more users profit from the additional bandwidth introduced into the network. Enhanced Inter-cell Interference Coordination (eICIC) has been introduced to solve interference problem. Scheduling for eICIC is used to provide best solution for interference mitigation, overload in macro cell, fairness in resource usage by users. In this paper we have analyzed Round Robin scheduling for eICIC, results prove that fairness is maintained between users and throughput has been improved. Key Words: LTE - Long term Evolution, UE - User Equipment, eNB – eNodeB.

Solution for intra/inter-cluster event-reporting problem in cluster-based pro...IJECEIAES
In recent years, wireless sensor networks (WSNs) have been considered one of the important topics for researchers due to their wide applications in our life. Several researches have been conducted to improve WSNs performance and solve their issues. One of these issues is the energy limitation in WSNs since the source of energy in most WSNs is the battery. Accordingly, various protocols and techniques have been proposed with the intention of reducing power consumption of WSNs and lengthen their lifetime. Cluster-oriented routing protocols are one of the most effective categories of these protocols. In this article, we consider a major issue affecting the performance of this category of protocols, which we call the intra/inter-cluster event-reporting problem (IICERP). We demonstrate that IICERP severely reduces the performance of a cluster-oriented routing protocol, so we suggest an effective Solution for IICERP (SIICERP). To assess SIICERP’s performance, comprehensive simulations were performed to demonstrate the performance of several cluster-oriented protocols without and with SIICERP. Simulation results revealed that SIICERP substantially increases the performance of cluster-oriented routing protocols.

This paper proposes an Embedded Ethernet which is nothing but a processor that is capable to communicate with the network. This helps in data acquisition and status monitoring with the help of standard LAN. Currently device with processor is widely used in industrial field. The Embedded Ethernet provides web access to distributed measurement/control systems and provides optimization for instrumentation, educational laboratories and home automation. However, a large number of devices don't have the network interface and the data from them cannot be transmitted in network. A design of ARM Processor based Embedded Ethernet interface is presented. In this design, data can be transmitted transparently through Ethernet interface unit to remote end desktop computer. By typing the IP address of LAN on the ARM9 board, the user gets sensor values on the PC screen at remote station. This provides the status of the devices at remote field. The user can also control the devices interfaced to the ARM9 Board by pressing the button displayed on the GUI of the remote Desktop PC.

Various parameters in the industries can be monitored and controlled using CAN bus network integrated with Bluetooth Communication. Monitoring and controlling the industrial parameters involve a large amount of man power and time consumption. To overcome the need of huge man power and time consumption this technology was developed which makes use of single person for monitoring and controlling the entire network. This method has been implemented in order to reduce the usage of wires used for communication purpose and also to reduce the errors relating to the data transfer. In this project sensors are used to sense the variable industrial parameters and the CAN protocols are used for error free data transmission and data reception purpose along with Bluetooth, pic micro controllers are used for programming the CAN controller. The data transmission rate will be higher than other wireless systems. This application is user friendly and it can be achieved at a very low cost.
Sensor Network to monitor Atmosphere for Green House and Agriculture SciencesKarthik Sharma
Greenhouses are one of the major ways in agricultural sciences to conduct research when they need a controlled environment. For the environment, the most important factors are temperature, pressure, humidity, etc. Providing a way of continuous monitoring of these environmental changes helps the users to understand and analyze these components in a better way. These facilities are spread over the vast area, which makes it ideal for a use of Wireless Sensor Network with a large number of nodes for monitoring data. The sensor network is a collection of the sensor nodes which will send the data to the base station at a particular interval. Here we used the MTS400 and IRIS notes to collect and send data. The main idea of this project is to collect the atmosphere changes and send data wirelessly to a central server, processes raw data and stores it and allows it to be analyzed and displayed as needed. In our project, we used a mySQL database to store the data. The data is then displayed in web pages which are developed using PHP and Javascript.
A novel Ethernet based processing system for remote source harmonic detectionTELKOMNIKA JOURNAL
This work is carried out to objectively establish a new method to detect harmonics and measure the total harmonic distortion (THD) in a remote source, such as a high voltage transformer. The proposed approach utilized embedded design techniques to construct an embedded processor system with Ethernet intellectual property core to acquire data from a remote harmonics source. The designed system has several notable merits, namely, it is portable that can be applied in the work field, and it avoids workers from being subject to a hazard high voltage shock as well as its simplicity and high accuracy. The harmonics detection and analysis are achieved by inserting a microcontroller system near the high voltage transformer to acquire the necessary data and transmit it to a remote embedded processor system that is used to detect and analyze the harmonics. The microcontroller and the processor systems are connected by a wide-area network (WAN) through Ethernet and transmission control protocol/internet protocol (TCP/IP) protocols. The processor system is accommodated to perform 128 points fast Fourier transform for harmonics detection. Matlab simulations are used to validate the results. It is found that the results match very accurately the simulation results with an error of less than 0.02%.

Epistemic Interaction - tuning interfaces to provide information for AI supportAlan Dix
Paper presented at SYNERGY workshop at AVI 2024, Genoa, Italy. 3rd June 2024
https://alandix.com/academic/papers/synergy2024-epistemic/
As machine learning integrates deeper into human-computer interactions, the concept of epistemic interaction emerges, aiming to refine these interactions to enhance system adaptability. This approach encourages minor, intentional adjustments in user behaviour to enrich the data available for system learning. This paper introduces epistemic interaction within the context of human-system communication, illustrating how deliberate interaction design can improve system understanding and adaptation. Through concrete examples, we demonstrate the potential of epistemic interaction to significantly advance human-computer interaction by leveraging intuitive human communication strategies to inform system design and functionality, offering a novel pathway for enriching user-system engagements.

Effective Application Security in Software Delivery lifecycle using Deployment Firewall and DBOM
The modern software delivery process (or the CI/CD process) includes many tools, distributed teams, open-source code, and cloud platforms. Constant focus on speed to release software to market, along with the traditional slow and manual security checks has caused gaps in continuous security as an important piece in the software supply chain. Today organizations feel more susceptible to external and internal cyber threats due to the vast attack surface in their applications supply chain and the lack of end-to-end governance and risk management.
The software team must secure its software delivery process to avoid vulnerability and security breaches. This needs to be achieved with existing tool chains and without extensive rework of the delivery processes. This talk will present strategies and techniques for providing visibility into the true risk of the existing vulnerabilities, preventing the introduction of security issues in the software, resolving vulnerabilities in production environments quickly, and capturing the deployment bill of materials (DBOM).

Abstract:Short distance data collection processes have problems. These can be termed as the repetition of
work at many steps, complexity involved in cable connections; the need of real time data processing and the
electromagnetic interference etc.We are proposing design of the system of data acquisition using LPC1768 and
virtual instrument. The system leverage Cortex-M3 core ARM processor for performing the data acquisition of
the closed environment, use the Bluetooth serial port module to implement the wireless data transmission, and
use the virtual instrument to handle the received data in the host machine. The system is recommended for
wireless data collection, the wireless hand-held meter reading and the industrial real time information
collection.
Keywords: Wireless communication; Bluetooth serial port; Virtual instrument
I. Introduction
Wireless communications technologies are continuously evolving over the last few decades and as any
technology is for the betterment of human life so application of technology is next step of it. The currently well-
known wireless communication technologies are Bluetooth, Wi-Fi, zigbee, IrDA, GSM etc. There are many
problems in any data collection process, this data can be anything. Typical problems involving in these are
repetitive human work which seeds the error, complex cable connections, need of real time data processing and
electromagnetic interference arising due to various electromagnetic mediums
If we consider the application range of various techniques, the cost involved in the data transmission,
security factors, reliability and other parameters, Bluetooth communications and wireless sensor networks are
the most appropriate method in short range wireless communication and data transmission. Further, the
Bluetooth technology can solve the problems mentioned above.
The proposed system shown here is making use of Bluetooth communication technology for wireless
data transmission, uses multiple sensors for data collection, and uses the virtual instrument software to monitor
and process the data arrived at all nodes .Multi-channel data acquisition, higher processing speed of the software
based on the short-range wireless data collection are the advantages of this system. System can be widely used
in many fields, such as short-range wireless data collection, handheld meter reading and industrial real time
information collection.
II. The Principle Of The Wireless Data Acquisition System
Wireless data acquisition system comprises of two parts, the part of the data acquisition and the part of
the data processing in the host computer. The data acquisition part of the sensor circuit handles the important
task of receiving the external signals, and these changeable signals can be amplified through the amplifier
circuit. Sensor circuit includes GAS sensor, Humidity sensor and temperature sensor. Gas Sensors are from MQ
Series .The amplified signal will undergo a process of AD conversion through the peripherals of the
microprocessor LPC1768, which have a 12-bit high-resolution ADC. According to the requirements of the PC

software, the converted data can be the collected for real-time transmission, or stored in FLASH, waiting for the
host computer to read. The wireless data collection systems also provide serial bus interface, which is used to
connect the serial bus sensor. 3.3V power supply provides the power to data acquisition system. In the machine
i.e. personal computer, there is a Bluetooth serial port receiver module, which is responsible for receiving all the
data returned from the slave machine. The data received from the slave unit will be accumulated on PC and can
be plotted graphically using MATLAB.
We have selected the ARM micro controller to develop embedded PLC. The reason behind this is its
wide use across many embedded designs due to competitive price, low power consumption, and wide variety of
peripherals available. LPC1768 micro controller of ARM cortex M3 will be used.

The LM35 series are precision integrated-circuit temperature sensors, with an output voltage linearly
proportional to the Centigrade temperature. Thus the LM35 has an advantage over linear temperature sensors
calibrated in ° Kelvin, as the user is not required to subtract a large constant voltage from the output to obtain
convenient Centigrade scaling. The LM35 does not require any external calibration or trimming to provide.
The Gas Sensor(MQ5) module is useful for gas leakage detection (in home and industry). It can detect
LPG, natural gas, town gas and so on. Because it has a fast response time once it has pre-heated, measurements
are almost instantaneous. Note that the sensitivity can be adjusted by the potentiometer

IV. Software Design, advantages, disadvantages
The wireless data acquisition software consists of two parts. The first one is the driver involved in the
hardware, which includes the driver of the gas sensor, Humidity sensor, Temperature sensor. The Cortex-M3 and
its peripherals, drive configuration of the Bluetooth Serial Module. In the hardware drivers, each one must be
properly configured. The most complex drivers are the Cortex M3 driver and the driver of the Bluetooth chip.
The second one is the Mat lab PC software programming on the PC side. The host computer software controls
each Bluetooth node and can enable data transmission and data processing. In the pc software design, the core is
the VISI hardware interface driver. The wireless data acquisitionsystem uses the VISI's serial port driver to
communicate with the wireless transmission module
Advantages:
1. Low cost and reliable
2. Can be programmed using embedded C.
3. Real time data processing can be achieved with less complexity in hardware
4. Because of wireless system, data can be accessed from anywhere
Disadvantages:
1. System may fails in the absence of electricity or on the discharge of battery
2. Calibration of sensors is needed
3. Transmission of data can be interrupted if Bluetooth is out of range
V. Results Obtained And Future Scope

We have also given feature to write this data to excel sheet. This captured data in excel sheet can be used
for analytics purpose. This analytics may be of any type to arrive at conclusion. The future scope for this project
is we can add any parameter in it. We have to design a suitable part to add that parameter and provide it’sout put
to ADC of the ARM processor. In this manner, we are increasing the scalability of the system. This unit can be fit
in to any industry. Considering the current parameters, it can be applied to chemical plant where temperature,
humidity and gas are the major parameters
