<h3><strong>&#39;Development of Fuzzy Logic Based Improved Schemes for Wireless Sensor Networks&#39;, Dr. Ashutosh Kumar Singh, Awarded in March 2014.</strong></h3>

<p style="margin-left:.5in">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.</p>

<h3><strong>&#39;Network Coding based Broadcasting and Multicasting over Wireless Network&#39;, Mr.&nbsp;Purnendu Shekhar Pandey, the research work is expected to be completed soon.</strong></h3>

<p style="margin-left:40px; text-align:justify">Broadcasting/ multicasting technologies over wireless networks have the potential of supporting several interesting and useful applications. There exist a great scope of improving the performances of the existing broadcasting/multicasting techniques and developing better alternatives. The Network coding theory has established its utility in improving throughput, delay, security, and robustness towards packet loss in wireless network. In this work, we are developing network coding based efficient broadcasting/ multicasting techniques and analyzing their performances using network simulator and other platforms. It has following&nbsp;objectives:&nbsp;1) Developing a protocol for&nbsp;identifying the potential nodes in the wireless network which should implement&nbsp;the&nbsp;network coding, choosing the best network coding scheme which should be used by each of&nbsp;these nodes.&nbsp;2) Developing a protocol for&nbsp;identifying the sub groups of the members of a multicast group which can form an alternate&nbsp;connection e.g. the&nbsp;primary&nbsp;multicast group may be over cellular network&nbsp;and&nbsp;the alternate connection may be the Bluetooth connections among some of the&nbsp;subgroups, developing a new multicasting strategy for efficiently delivering the multicasting packets to the members of these subgroups and then delivering all packets to each member of these subgroups using network coding scheme.&nbsp;3) Unifying the above two&nbsp;protocols.</p>

<h3><strong>&#39;Exploration of Physical Layer Technologies for Improving the&nbsp;Performance of Wireless Networks&#39;, Mr. Mahendra Shukla,&nbsp;the Literature survey and course work is going on.</strong></h3>

<p style="margin-left:40px; text-align:justify">The last decade saw an evolution of radio access network for mobile communication systems. Orthogonal Frequency Division&nbsp;Multiplexing (OFDM) remains as the transmission&nbsp;technology in such system. The evolution is progressing in full steam and&nbsp;researches are looking ahead to&nbsp;5G. The 5G systems are being conceived to support a large variety of operating scenarios.&nbsp;Many of those&nbsp;pose a great challenge to OFDM because of large symbol duration, high out of band (OoB) radiation and&nbsp;stringent synchronization requirements of OFDM. Thus, there is a great scope of research for developing&nbsp;better physical layer for 5G network. The main objectives of this research are, 1)&nbsp;Comparative study of FBMC, UFMC and OFDM Technologies. 2)&nbsp;Exploring the scope of improvement in various multicarrier modulation techniques. 3)&nbsp;Exploring the possibility of developing better alternatives for multicarrier modulation based physical&nbsp;layer as compared to existing proposals/techniques. 4)&nbsp;Extending the concept of trellis coded modulation technology by integrating the space time coding&nbsp;along with modulation an&nbsp;error control coding. 5)&nbsp;Evaluating the performance of aforementioned scheme over MIMO systems.</p>
