My areas of Research include Resource allocation for Multicast/Broadcast Communication Systems, Small/Femto-Cell Networks, Cognitive Radios, MEC, IRS, FOG Computing, Block-chain for Communication, D2D Communication, V2V Communication, Cloud-RAN, IoT, GNSS Signal Processing, SDR, Evolutionary Algorithms and their use in Engineering Applications (mainly Signal and Image Processing) etc. Currently I am working in Collaboration with professors in leading universities such as NTU Singapore, The Hongkong Polytechnic University, Hongkong and Ryerson, University, Canada, Cranfield University, U.K, Newcastle University, U. K, Ohio University USA.
Current Research:
I am currently working on following research projects/areas:
GNSS Signal Processing:
1. Advanced Signal Processing Techniques for Performance Enhancement of GNSS Software Receiver. (Hardware: USRP/DSP Board/FPGA; Software: MATLAB, LabView).
2. Machine Learning based GNSS Scintillation, interference, multipath etc detection, classification and mitigation. (Software: MATLAB, Python, LabView).
3. Machine Learning based Satellite selection for GNSS Software Receiver. (Software: MATLAB, Python, LabView).
IoT and Image/Video Processing:
4. Real time IoT and GNSS based Navigation, Localization and monitoring of High Speed Vehicles. (Software: MATLAB, Python, LabView).
5. Machine Learning based identification and classification of high speed vehicles from videos. (Software: MATLAB, Python, LabView).
4G-5G Communication
6. Energy Efficiency and Resource allocation in MEC/FOG Computing/D2D/ V2V/ Cloud RAN/ HetNets etc. (Software: MATLAB, Python, LabView).
For Resource allocation we use Machine Learning, Evolutionary Algorithms and other Optimizations tools such as Convex Optimization toolbox, Game theory, Matching theory etc.
Funded Projects:
1. ISRO/RES/3/720/2016-17 Development of Software Defined Radio (SDR) Based GNSS (GLONASS + IRNSS) Receiver. Funded By: ISRO under RESPOND.
We designed a multi-constellation muti-frequency Software receiver both in MATLAB and in LabView separately.
The developed Software Receiver is capable of providing individual and hybrid solution for following constellations as of now:
1) IRNSS L5 / IRNSS S/GPS L1 / GLONASS L1
2) IRNSS L5 + GPS L1 + GLONASS L1
3) IRNSS S + GPS L1 + GLONASS L1
4) GPS L1 + GLONASS L1
Salient Features:
1. LabView based SDR, which allows simultaneous and parallel tracking of the acquired satellites from different constellations and/or different frequencies. It also allows to use hardware accelerators such as Multi-core, Multi-threading (SIMD) etc. Therefore, significantly reduces the overall execution time.
2. Improved reliability, availability and accuracy especially in an environment with limited satellite visibility, such as in urban or mountainous areas.
3. Interoperability provides user a PNT solution using signals from different GNSS systems.
4. Iono-Grid corrections and Tropospheric corrections provided with user selectable option. GUI with options for end user to select Iono-grid and/or Tropospheric corrections.
5. MENU driven user configurability for acquisition, tracking thresholds, satellite elevation mask angle, selection of satellite channels etc.
6. MENU selectable option for real time display of observables such as I/Q correlation values, C/N0, GDOP, PVT solutions, XYZ coordinates of selected satellite etc.
7. SDR provides session wise time stamped logs for various observables such as C/N0, PR, Navigation message of all the channels, SV time, PVT logs, GDOP etc. for post processing.
8. Real time visualization of PSD of received satellite signals.
2. Work Oder No. 11/401/UWR(G)/110(P) regarding Indigenous Development of Automated Correlation System, for Under Water Ranges DRDO, Goa.
As Co-PI:
Cloud Based Analytical Sensor Test Kit for Advanced Process Control, funded by Melinda & Gates foundation in collaboration with Prof Srikanth Mutnuri, Head Biological Sciences, BITS Pilani K K Birla Goa Campus, Crainfield University UK and Ohio University USA.
My Part was to develop a plug and play kind of IoT based Sensor kit which is capable of transmitting real time data from different sensor to Azure and Google cloud. The indigenous devices developed for communication is called “Cube” which is a solar powered (self sustained) device. It used XBee 3G for communication. The end user can communicate with the cube using developed web/mobile application. The end user can plug any sensor and just to need to provide the upper and lower threshold for warnings or control. The application automatically updates the system as per the inputs provided by the end user.
The best part is that the end user required no knowledge of programming to use this device.
