A multifarious study on Low-Power Wide-Area Networks
The Department of Electronics and Communication Engineering is delighted to announce that Assistant Professor Dr Anirban Ghosh and Research Scholar Mr Naga Srinivasarao Chilamkurthy have published their article titled “Low-Power Wide-Area Networks: A Broad Overview of its different aspects” in IEEE Access, a Q1 Journal, having an Impact Factor of 3.476. The work was published in collaboration with Dr Om Jee Pandey from the Indian Institute of Technology BHU, Dr Cenkeramaddi Linga Reddy from the University of Agder, and Dr Hong-Ning Dai from Hong Kong Baptist University, Hong Kong.
This is a survey article on Low-power Wide-area networks which provides a detailed description of LPWAN technologies in the context of IoT applications. In this survey article, they review and provide an overarching description of LPWAN in terms of design goals, techniques to improve design objectives, and system architecture. They have also evaluated several existing and non-standardized LPWAN technologies and the market opportunities of LPWAN. With the help of this article, the researchers can choose the best LPWAN technology for their specific applications.
The practical implementation of the article can be found in various social and commercial applications such as smart healthcare, intelligent transportation, climate-smart agriculture, rescue operations, logistics, smart cities, industries, utilities, smart buildings, consumer electronics, security, asset tracking, smart waste management systems, cognitive manufacturing, and Machine-to-Machine (M2M) communications. Their future research plans include working on Wireless Sensor Networks, Low-Power Wide-Area Networks, Small-World Networks, and applying machine learning and reinforcement learning techniques in the context of wireless networks for cyber-physical systems and IoT applications.
Abstract of the Research
Low-power wide-area networks (LPWANs) are gaining popularity in the research community due to their low power consumption, low cost, and wide geographical coverage. LPWAN technologies complement and outperform short-range and traditional cellular wireless technologies in a variety of applications, including smart city development, machine-to-machine (M2M) communications, healthcare, intelligent transportation, industrial applications, climate-smart agriculture, and asset tracking. This review paper discusses the design objectives and the methodologies used by LPWAN to provide extensive coverage for low-power devices. We also explore how the presented LPWAN architecture employs various topologies such as star and mesh. We examine many current and emerging LPWAN technologies, as well as their system architectures and standards, and evaluate their ability to meet each design objective. In addition, the possible coexistence of LPWAN with other technologies, combining the best attributes to provide an optimum solution is also explored and reported in the current overview. Following that, a comparison of various LPWAN technologies is performed, and their market opportunities are also investigated. Furthermore, an analysis of various LPWAN use cases is performed, highlighting their benefits and drawbacks. This aids in the selection of the best LPWAN technology for various applications. Before concluding the work, the open research issues, and challenges in designing LPWAN are presented.

Prof G S Vinod Kumar to be the Chief Faculty Mentor of Patent Maker
The Hatchlab Research Centre has been nurturing innovative ideas and inspirational ambitions for paving the way to an extraordinary tomorrow. Patent Maker was the beginning of a new chapter in these explorations, armed with the potential to work out the unworkable. The Directorate of Entrepreneurship and Innovations and is glad to announce that Prof G S Vinod Kumar, Department of Mechanical Engineering, has been appointed as the Chief Faculty Mentor of Patent Maker.
Prof G S Vinod Kumar, an expert, mentor, and multidimensional professional, has been there from the very inception of this initiative. Patent Maker is a common platform which will not only facilitate the conversion of ideas, products, concepts, and research papers to patents but will also help them commercialise with the help and support of the industry. It encourages every aspirant who wants to contribute to the nation and bridges the gap between industry and academia.
Hatchlab Research Centre believes in the power of connection and creates opportunities for students to converse their field of interest with experts around the map. The team actively engages in the university’s innovation, research, and entrepreneurship activities. The focus also relies on concreting a start-up ecosystem with the help of corporates, enablers, world-class mentors, top-class institutions, foundations, incubators, and the government. Patent Maker is one of the biggest initiatives of the Hatchlab Research Centre. It aspires to be a support system for projects and patents that deserve a high commercial application.

SRM University- AP inked MoU with Rennes Business School
Indo-French diplomatic relations have always tailored development across all major disciplines. SRM University- AP has inked an MoU with the Rennes School of Business on August 23, 2022. The two institutions agreed to promote mutually beneficial activities in education, research, and other academic areas. The alliance in specific targets the internationalisation of higher education.
SRM University- AP aspire to strengthen the ties with Rennes School of Business following the mutual interests in delivering programmes of academic excellence and cultural diversity. Honourable Vice-Chancellor Prof V S Rao commented that the collaboration would open the gates of higher studies and research work for SRM University- AP and Rennes Business School. Both institutions are determined to work together with the spirit of prolific international relations and academic cooperation.
Dr Thomas Froehlicher, Dean, Rennes School of Business, and Ms Maud LE BARS, South Asia Area Manager, Rennes School of Business, were the delegates who visited the campus to sign the MoU. “India and France share common historical events and many cultures. This collaboration will benefit both the nations and the students”, said Dr Thomas as he briefed his thoughts on the alliance.
The coordination between the institutes may include but is not limited to progression programmes and semester abroad programmes. The agreement looks forward to organising executive programmes for the professional community, joint research projects, joint conferences and publications, exchange of faculty members, collaborative virtual student projects, short study abroad seminars, executive education, and admission to degree-seeking students on a fee-paying basis.
Dr Bharadwaj, Dean SEAMS, Dr CA Mahalakshmi Mudliar, Associate Professor of SEAMS, and Dr Naga Swetha Pasupuleti, Associate Director of International Relations, had a vigorous discussion with the Rennes business school representatives regarding the areas of collaboration. Dr R Premkumar, Registrar and Dr Thomas Froehlicher, Dean of Rennes Business School, signed the MOU and exchanged the documents.

DST-SATHI cluster with KLU, ANU, Vignan University and AIIMS
SRM University-AP formed a cluster with Acharya Nagarjuna University, KL University, Vignan University, and AIIMS Mangalagiri for the DST-SATHI initiative of the Ministry of Science and Technology. Sophisticated Analytical & Technical Help Institute (SATHI) aims to provide professionally managed services with efficiency, accessibility and transparency of the highest order under one roof to service the demands of industry, start-ups and academia. Dr P Siddaiah – Dean, Acharya Nagarjuna University; Dr Mukesh Tripathi, Director-AIIMS Mangalagiri; Dr G Pardha Saradhi Varma – Vice Chancellor, KL University; and Dr P Nagabhushan – Vice Chancellor, Vignan University; attended the meeting held at SRM University-AP campus on Monday.
SRM AP Vice-Chancellor Prof V S Rao invited the Vice-Chancellors of the respective universities to come forward for the formation of a cluster for the ‘SATHI’ programme. Pro-Vice Chancellor Prof D Narayana Rao did an elaborate presentation on DST projects. “The host institute, which is the lead partner in the cluster, will have to provide a functional space of 20,000 square yards, and SRM University-AP is suitable for this in every way”, Prof D Narayana Rao said. “The equipment worth Rs 75 crore to be provided through the SATHI programme will help in carrying out extensive research in all the five universities,” he added. The Vice-Chancellors and Directors of these 5 institutions have agreed to form the cluster and submit the proposal to the Department of Science & Technology (DST), Government of India.
