  • Performance Evaluation of ZigBee Protocol in Lunar Wireless Sensor Network Deployments
    Kaival Prajapati, Sachin Gajjar
    Proceedings of the 9th International Conference on Electronics Communication and Aerospace Technology Iceca 2025, 2025
    Wireless sensor networks (WSNs) are expected to play a key role in future lunar surface missions, enabling environmental monitoring, infrastructure health tracking, and in situ resource utilization (ISRU). Lunar exploration supports sustainable operations, habitat development, and autonomous surface monitoring; however, protocol-specific studies—particularly for low-power ZigBee (IEEE 802.15.4) remain largely unexplored in such extreme environments, which motivates this work. This paper presents a MATLAB-based simulation framework to evaluate ZigBee, under lunar-specific constraints. The model integrates beacon-enabled superframes, guaranteed time slots (GTS), CSMA/CA contention, duty cycling, and reconfiguration mechanisms, while accounting for free-space path loss, crater-induced attenuation, shadowing variability, and terrain-dependent busy probabilities. A detailed energy model covering transmit, receive, idle, and sleep states is also incorporated. Simulation results over a 14-day lunar cycle show that ZigBee sustains low-data-rate sensing with an average packet delivery ratio of ~33.18% and throughput and goodput of 5.8684 bps and 2.1814 bps, respectively. The corresponding FND, HND, and LND are observed at 1.23, 6.60, and 11.92 days, demonstrating ZigBee's feasibility for long-duration, energy-constrained lunar WSN applications.
  • Improved fuzzy-driven clustering and routing protocol for underwater wireless sensor networks

  • Design, Development, and Testing of Real Time Intelligent Traffic Control System using FreeRTOS
    Divyani Patel, Devanshu Upadhyay, Sachin Gajjar
    Conference Proceedings 2025 4th International Conference on Advances in Computing Communication Embedded and Secure Systems Access 2025, 2025
    This paper presents a Real-Time Intelligent Traffic Signal Control System (RTITSCS) designed to optimize urban traffic flow by dynamically adjusting signal phases based on real-time vehicle density. Unlike conventional fixed-timing systems that allocate equal green time to all lanes, RTITSCS utilizes infrared (IR) sensors for precise vehicle detection and employs FreeRTOS for efficient real-time task management. FreeR-TOS enables rapid signal adjustments, improving responsiveness to traffic conditions. Analytical evaluation demonstrates that RTITSCS reduces average vehicle wait time from 6 seconds in a fixed-timing system to 2.49 seconds — a 58.5% improvement. This reduction in idling time leads to a corresponding 58.5% decrease in fuel consumption and CO<inf xmlns:mml="http://www.w3.org/1998/Math/MathML" xmlns:xlink="http://www.w3.org/1999/xlink">2</inf> emissions, enhancing energy efficiency and environmental sustainability. With real-time adaptability, minimal infrastructure modifications, and cost-effectiveness, RTITSCS offers a scalable solution for smart city traffic management.
  • Implementation and testing of single point positioning on IRNSS/NavIC receiver data
    Mahek Vyas, Sachin Gajjar, Manisha Asit Upadhyay, Rajat Acharya
    International Journal of Communication Systems, 2024
    SummaryIndia has developed its own regional navigation satellite system called the Indian Regional Navigation Satellite System (IRNSS), also known as Navigation with Indian Constellation (NavIC). IRNSS/NavIC provides standard positioning and timing services for civilians and restricted services for authorized users. In this paper, single point positioning is implemented on the NavIC receiver data. Estimation techniques of the least squares method and extended Kalman filter are implemented after applying broadcast‐based clock corrections, orbit computation, relative time correction, and ionosphere delay correction for single and dual frequency. A data extraction and storage module is developed to store computed parameters at every intermediate stage in separate files. This is followed by an error plotter module to plot the extracted parameters for each satellite and to separately analyze their performance and the obtained errors. The estimated receiver position is visualized on Google Earth. The absolute error in both estimation techniques ranges between 5 and 15 m throughout the period.
  • Design and UVM based Verification of UART, SPI, and I2C Protocols
    Nishant Sahay, Sachin Gajjar
    Proceedings of the 5th International Conference on Smart Electronics and Communication Icosec 2024, 2024
    There are several hardware communication protocols available today, but the three most prevalent and frequently used are UART (Universal Asynchronous Receiver Transmitter), SPI (Serial Peripheral Interface), and $\\mathbf{I}^{\\mathbf{2}} \\mathbf{C}$ (Inter-Integrated Circuit). This article discusses the working, implementation and verification of these protocols. It aims to highlight the difference in hardware requirements for implementation of each of these designs, and the difference in the approach of verification of these designs. The implementation of the design is done using Quartus Prime tool. An FSM is designed for each of these protocols which is then used to write the Verilog code for the design. The design is then synthesized for Cyclone V SE Base FPGA board. The resource utilisation for each protocol is discussed based on Combinational ALUTs and Dedicated Logic Registers used. UVM (Universal Verification Methodology) based verification is preformed for each of the design. A verification environment is developed using UVM. These environments were then compiled in QuestaSim 10.7c. UVM sequences are used to create the stimuli. The verification for each protocol differs in term of the sequences that are applied. UART verification proves to be a lot more challenging because of different parameters that are configurable, such as setting the baud rate, data length, stop bits and parity types. While SPI and $I^{2} \\mathbf{C}$ have a similar type of sequences which are used for their verification, these are read, write, reset, and error sequences. However, upon implementation it can be seen that $I^{2} \\mathbf{C}$ proves to be more resource efficient.

  • Fuzzy-based unequal clustering protocol for underwater wireless sensor networks
    Hetal Panchal, Sachin Gajjar
    International Journal of Communication Systems, 2023
    SummaryUnderwater wireless sensor network (UWSN) is a network made up of underwater sensor nodes, anchor nodes, surface sink nodes or surface stations, and the offshore sink node. Energy consumption, limited bandwidth, propagation delay, high bit error rate, stability, scalability, and network lifetime are the key challenges related to underwater wireless sensor networks. Clustering is used to mitigate these issues. In this work, fuzzy‐based unequal clustering protocol (FBUCP) is proposed that does cluster head selection using fuzzy logic as it can deal with the uncertainties of the harsh atmosphere in the water. Cluster heads are selected using linguistic input variables like distance to the surface sink node, residual energy, and node density and linguistic output variables like cluster head advertisement radius and rank of underwater sensor nodes. Unequal clustering is used to have an unequal size of the cluster which deals with the problem of excess energy usage of the underwater sensor nodes near the surface sink node, called the hot spot problem. Data gathered by the cluster heads are transmitted to the surface sink node using neighboring cluster heads in the direction of the surface sink node. Dijkstra's shortest path algorithm is used for multi‐hop and inter‐cluster routing. The FBUCP is compared with the LEACH‐UWSN, CDBR, and FBCA protocols for underwater wireless sensor networks. A comparative analysis shows that in first node dies, the FBUCP is up to 80% better, has 64.86% more network lifetime, has 91% more number of packets transmitted to the surface sink node, and is up to 58.81% more energy efficient than LEACH‐UWSN, CDBR, and FBCA.

  • Design, Development and Testing of Electronic Control Unit Prototype in an Electric Vehicle
    Riththika Sukanandan, Sachin Gajjar
    Proceedings 2023 IEEE International Symposium on Smart Electronic Systems Ises 2023, 2023
    An Electronic Control Unit (ECU) acts as a vehicle's the central hub, managing functions through microcontrollers that interpret sensor input and ensure smooth operation. Over 50 microcontrollers govern the operation of low-voltage components like indicators, horns, regenerative brakes, air conditioners, power windows and airbag deployment to monitor control, and enhance diverse aspects, such as engine and motor modules' suspension, powertrain, transmission, brakes, and body functions. This paper delves into the hardware design of an electric vehicle powered by a 48V Lithium Nickel Manganese Cobalt Oxide (Li-NMC) battery. To efficiently utilize this voltage, a buck converter steps it down to 12V for the low-voltage system, with voltage regulators further reducing it to 5V for the microcontroller board's operation. Inputs from buttons like start, brake, charge, accelerator, forward, and reverse are processed by the microcontroller board and Motor Controller. They, in turn, control various LED pins to indicate different states of the car system. The system, designed for an all-terrain vehicle, underwent rigorous testing with a Brushless Direct Current (BLDC) motor, achieving 45 km/hr and 5.16 m/s2 acceleration. The implementation uses an Arduino board and C language to enhance the vehicle functionality by enabling user interactions, such as starting the car, applying brakes, charging, and controlling acceleration, all while providing clear visual feedback through LED indicators. This paper exemplifies the potential of readily available microcontroller applications for EVs and provides a forward looking vision for an all-terrain four-wheel electric vehicle, showcasing the energy-efficient utilization of low-voltage systems through readily available electronic circuit boards.
