Research Projects & Experiments :
(I) Integrate Indoor Location System with Virtual World:
The indoor localization system had been modified to fit on a small autonomous ground robot. The accuracy of the location estimation is increased by implementing Kalman filter. The robot had been modeled in a virtual world environment, "Second Life", where the model would move accordingly the movement of the actual robot.
(II) Pan/Tilt/Zoom Camera Control using Wireless Sensor Network:
Developed an algorithm to transform the indoor location coordinates to the angles for PTZ camera. A successful system had been developed for dynamic tracking of the object equipped with the cricket motes, being used to obtained position.
(III) MAV II:
Worked on navigation and localization of Micro Air vehicle (MAV). Various efforts were made for successful collaboration between MAV and Unmanned Ground Vehicle (UGV) with sharing location and sensor information.
(IV) Wireless Sensor Network integration with Layered Sensing Test-bad:
'NASA World Wind' software was used as layered sensing test-bad for the various sensor data coming from the wireless sensor network. The stationary camera system was integrated as a layer for a particular location on the map.
Wireless Projects :
(I) Simulation of MIMO for CDMA and MC-CDMA:
Successfully designed and simulated Multi Input Multi Output (MIMO) system for CDMA using MATLAB. Expanded the designed system for MC-CDMA. Theoretical and simulation results were compared and precise agreement was achieved.
(II) Simulation of Multi User Detection (MUD) and Multi Carrier (MC) CDMA systems:
Programmed and simulated Code Division Multiple Access technique for flat fading channel. The same project is then expanded to simulate Multi Carrier CDMA with Multi User Detection (MUD). MATLAB was used for programming and a final report was submitted in IEEE format.
(III) Simulation of OOK, FSK and QAM schemes :
Simulated various modulation techniques such as on-off keying, frequency-shift keying, quadrature amplitude modulation and phase-shift keying in flat fading channel using MATLAB.
(IV) Opnet Simulation of OSPF protocol :
Designed and implemented a virtual computer network to test OSPF protocol using Opnet simulator. Successful test results are reported in IEEE format and presented using PowerPoint in class.
(V) Advance Computer Networks :
A review paper on localization, tracking and navigation using wireless sensor network was submitted in IEEE format. Complete reviews of various localization and tracking techniques were studied. Mesh Networking protocol for wireless sensor network was studied.
Undergrad Projects :
(I) Embedded Linux based remote terminal unit using Ethernet :
The project was successfully designed and implemented as a requirement for the degree. The main objective of the project was to develop a real time data acquisition system for factory automation and remote control using embedded Linux based Real-Time Operating System (RTOS). Successfully designed and developed the embedded hardware and embedded C was used as programming language for the basic socket programming on the embedded Linux.
(II) BPSK and QPSK Simulation :
Simulated generalized BPSK and QPSK modulation concept using C++ language.
