'Development of Fuzzy Logic Based Improved Schemes for Wireless Sensor Networks', Dr. Ashutosh Kumar Singh, Awarded in March 2014.

Fuzzy logic based schemes were developed for clustering and other important tasks of WSN. The performance of these schemes was compared with other alternative approaches.Further, the applications of WSNs with movable sink were explored. The fuzzy logic based schemes with various plausible movements for such type of WSNs were developed and their performance analysis was done.

'Implementation of Network Coding Schemes for Efficient Data Streaming over D2D assisted Cellular Network', Mr. Purnendu Shekhar Pandey, the thesis is to be submitted shortly.

We have exploited the network coding and Device-to-Device (D2D) Communication with the aim of reducing the cellular network traffic for data streaming applications which involve delivering exactly same data (e.g. television, news, sports, etc. applications) to several spatially closely located mobile stations (MSs). We emphasized on the development of easily implementable schemes for better end-to-end data delivery, thus an experimental setup has been created using Android Studio and supported mobile phones. Within the associated practical constraints of the experimental setup a customized scheme has been developed for D2D assisted data streaming. Moving ahead, we modelled the system as a graph and proposed Matroid based spanning tree selection scheme for addressing the node selection problem for network coding in the dynamic scenario. A clique based scheme is also proposed for dealing with the problems of complex network generation associated with Connecting Dominating Set Network Coding (CDS-NC) and Tree-NC approaches. Performance evaluation of these schemes has been carried out on NS-3 simulator and the results along with other competitive approaches have been analyzed.

'Study of Rate Conversion Filtering for Cognitive Radio', Mr. Abhishek Kumar, Ongoing.

Cognitive radio technology involves reliable data transmission over dynamically available spectrum bands of different bandwidths. It requires spurious transient free rate conversion filters which should have lower computational complexity too. Development of a novel rate conversion filter which should meet the aforesaid requirements of cognitive radio is the primary aim of this research work. Its scope includes the exploration of spectrum blind sampling and other relevant techniques which contribute in improving the overall performance of the cognitive radio technology. The outcome of this research can enhance the commercial viability of the cognitive radio technology.

'Performance Evaluation and Optimization of Cellular Two-Way Relay Networks with Spatial Diversity', Mr. Mahendra Shukla, Ongoing (Dr. Suneel Yadav is another Supervisor)

The aim is to evaluate and optimize the performance of two- way AF relay in cellular context under various fading channels. With this, we will analyze several performances measure such as outage probability, symbol error rate and ergodic sum-rate. In addition we will optimize the system performance by optimizing the several factors such as power allocation, relay location, joint power allocation and traffic asymmetric parameter. 

'Explication of SAR Polarimetry and its applications', Ms. Nidhi Verma, ongoing. (Dr. Pooja Mishra is another Supervisor)

This research aims to contribute in improving the Synthetic Aperture Radar Polarimetry technology and to explore new applications wherein this technology can be used for gaining some useful information.

'Design of quantum gates by interacting quantum elactromagnetic field by N-level atom having NXN hemiltonion matrix with a small random perturbation' Ms. Preeti Kharwar, ongoing. (Prof. Harish Parthasarathy, NSIT New Delhi is another Supervisor)

This research aims to contribute in the possible development of a computer which should follow the quantum principles.
