    A large section of the population around the globe is migrating towards urban settlements. Nations are working toward smart city projects to provide a better wellbeing for the inhabitants. Cyber-physical systems are at the core of the smart city setups. They are used in almost every system component within a smart city ecosystem. This paper attempts to discuss the key components and issues involved in transforming conventional cities into smart cities with a special focus on cyber-physical systems in the Indian context. The paper primarily focuses on the infrastructural facilities and technical knowhow to smartly convert classical cities that were built haphazardly due to overpopulation and ill planning into smart cities. It further discusses cyber-physical systems as a core component of smart city setups, highlighting the related security issues. The opportunities for businesses, governments, inhabitants, and other stakeholders in a smart city ecosystem in the Indian context are also discussed. Finally, it highlights the issues and challenges concerning technical, financial, and other social and infrastructural bottlenecks in the way of realizing smart city concepts along with future research directions

    This paper presents a comprehensive analysis of the scholarly footprint of ChatGPT, an AI language model, using bibliometric and scientometric methods. The study zooms in on the early outbreak phase from when ChatGPT was launched in November 2022 to early June 2023. It aims to understand the evolution of research output, citation patterns, collaborative networks, application domains, and future research directions related to ChatGPT. By retrieving data from the Scopus database, 533 relevant articles were identified for analysis. The findings reveal the prominent publication venues, influential authors, and countries contributing to ChatGPT research. Collaborative networks among researchers and institutions are visualized, highlighting patterns of co-authorship. The application domains of ChatGPT, such as customer support and content generation, are examined. Moreover, the study identifies emerging keywords and potential research areas for future exploration. The methodology employed includes data extraction, bibliometric analysis using various indicators, and visualization techniques such as Sankey diagrams. The analysis provides valuable insights into ChatGPT's early footprint in academia and offers researchers guidance for further advancements. This study stimulates discussions, collaborations, and innovations to enhance ChatGPT's capabilities and impact across domains.</p

    Quality of Service aware Dynamic Source Routing Protocol in Ad hoc Networks: Proposal, Analysis and Comparison

    A Mobile Ad hoc Network (MANET) is a self-configured, infrastructure less network. Due to mobility of nodes routing is a very critical issue in MANETs. Finding and selecting an optimal and reliable path that can exist as long as possible is a complex task. Dynamic Source Routing (DSR) protocol is an on demand or reactive, source driven routing protocol. By implementing Dynamic Source Routing, we can design a self configured, infrastructure less multi hop wireless ad hoc network which has dynamic topology with mobile nodes. DSR has low overheads and require less convergence time if an existing route is failed. In DSR protocol periodic routing updates or route advertisement are not disseminated by a node to its neighbors and DSR does not perform link status sensing, these features make DSR a protocol with less overhead. Basic model of Ad hoc network depends on Best Effort delivery and not provide any guarantee of Quality of Service constraints like minimum bandwidth requirement and maximum allowable delay. Basic frame work of DSR also does not support Quality of Service constraints. In this research paper we will propose a QoS aware DSR and we will analysis and compare our proposed QoS-DSR protocol with traditional Dynamic Source Routing protocol
