Prof. Mehta has made fundamental contributions to the modeling, design and analysis of opportunistic selection and adaptation in modern wireless communication systems, with applications to green wireless sensor networks, 4G/5G cellular radio systems, opportunistic selection, cooperative relaying, and cognitive radio.
His research on green energy harvesting networks, which exploit renewable energy and promise perpetual operation, is getting increasingly well-cited. It has highlighted several new design challenges and trade-offs that arise in these networks [J4][J12][J23][J43]. His original work on hybrid sensor networks, which consist of a mixture of energy harvesting and conventional sensor nodes, is the first to investigate this important and new class of networks [J14]. It revisits fundamental issues such as new performance measures to evaluate and compare such networks, and how to compute them efficiently. His seminal investigation in [J43] establishes the benefits of exploiting energy harvesting in cooperative relays.
He and his group in IISc have pioneered best-in-class, distributed, scalable algorithms for opportunistically selecting the best node from among the available nodes in a wireless system. These find applications in many contemporary wireless systems such as cellular radio, cooperative relaying, cognitive radio, and wireless sensor networks [J9][J17][J22][J32][J37][J45]. The structural properties that he has proved about the optimal timer algorithm have led to new computationally-efficient methods for designing and applying these popular algorithms in many opportunistic wireless systems [J10][J21][J24][J47]. He was also awarded the Swarnajayanti Fellowship for the year 2014-15 for his research proposal on new opportunistic selection algorithms.
His group has also developed energy-efficient training schemes to acquire channel state information required for opportunistically selecting a subset of the available antennas in multi-antenna capable nodes [J25][J26][J41][J44][J46][J48]. These enable the use of low-complexity multi-antenna selection technologies in 4G/5G cellular standards [J33]. Another well-known contribution by Prof. Mehta is his novel analytical framework, which is based on the concept of an effective exponential signal-to-noise-ratio mapping (EESM). It helps characterize and optimize the performance of feedback schemes in 4G cellular standards [J11][J19][J38][J39]. This has also led to novel adaptation and scheduling algorithms for reduced feedback schemes that improve cell throughput without additional feedback [J1][J3].
Cooperative communications is another technology of relevance to 5G cellular systems, to which Prof. Mehta has made several important, well-recognized recognized contributions. These include his highly cited earlier works on relay selection for cooperative beam-forming [J55] and rateless codes-based relaying [J42], which establish the benefits and fundamental limitations of cooperative techniques. His substantial body of work on optimal adaptation, relaying, and selection policies in interference-constrained cognitive radio systems is noteworthy for its systematic development of the optimal policies, and the order of magnitude performance gains achieved over ad hoc approaches pursued in the literature [J5][J6][J7][J13][J15][J16][J20][J30]. This research vastly improves the potential of the promising cognitive radio technology to effectively address the significant spectrum shortage faced currently by wireless operators in India.
(b) Impact of the contributions in the field concerned:
Prof. Mehta’s research work has led to the new advances in the design and evaluation of energy harvesting-based green wireless sensor and relaying networks. This is an impactful area of research today given the focus on the telecommunications industry and society on green, energy-efficient communications. His research vastly improves cognitive radio’s potential to effectively address the significant spectrum shortage faced by society today. His work on selection algorithms and adaptation finds applications in opportunistic techniques, which play a vital role in current and next generation wireless cellular systems, vehicular networks, and sensor networks. His work advances Indian technology in cellular standards.
