Relevant Projects

Development of Embedded Linux Device Drivers

Wrote applications to interact with sensors and display devices on an ARM9 single-board computer utilizing both Linux driver APIs and directly accessing I/O registers from user space.

Evaluation of Handoff Performance in IEEE 802.11 (Wi-Fi) Wireless Networks

Layer 2 and layer 3 handoff performances of mobile WLAN devices were tested in 5 GHz band using mesh-connected and isolated access points. Correlation between handoff latency and various mobile device parameters such as number of channels scanned, permitted data rates, etc. was established.

Simulation Study of Routing Protocols for Mobile Ad hoc Networks

The project involved comparison of DSR and AODV routing protocols using ns-2 in a simulated urban environment. Data was transferred between mobile nodes over TCP connections. Performance was evaluated based on packet delivery ratio, latency, and routing load. Bash scripts were written for analyzing trace files.

Simulation Study of 4G Communication Systems

Physical layer of the uplink part of WiMax and LTE systems, which use OFDMA and Single Carrier-FDMA, was studied through simulations. Advantage of SC-FDMA in terms of peak-to-average power ratio and use of frequency domain equalization at the base station was explored.

Development of Dynamometer Platform for Validation of Nonlinear Control Algorithms

A fractional-horsepower dynamometer platform was developed to test nonlinear and adaptive control schemes using hardware-in-the-loop simulations using MATLAB or LabVIEW. Controllers including sliding mode control and adaptive friction compensation were validated on the setup.

Design and Development of a PLC-based Elevator Control System

A three-floor elevator model was designed and built using DirectLogic06 PLC as the main control unit. It was used to teach basic PLC programming to a senior-level Controls class.
