Seamless Integration

Light Fidelity (LiFi) is a new candidate for wireless networking that utilizes the visible light spectrum and exploits the existing lighting infrastructure in the form of light-emitting diodes (LEDs). It provides point-to-point and point-to-multipoint communication on a bidirectional channel at very high data rates. However, the LiFi has small coverage, and its optical gain is closely related to the receiver’s directionality vis-à-vis the transmitter, therefore it can experience frequent service outages. To provide reliable coverage, the LiFi is integrated with other networking technologies such as wireless fidelity (WiFi) thus forming a hybrid system. The hybrid LiFi/WiFi system faces many challenges including but not limited to seamless integration with the WiFi, support for mobility, handover management, resource sharing, and load balancing. The existing literature has addressed one or the other aspect of the issues facing LiFi systems. There are limited free source tools available to holistically address these challenges in a scalable manner. To this end, we have developed an open-source simulation framework based on the network simulator 3 (ns-3), which realizes critical aspects of the LiFi wireless network. Our developed ns-3 LiFi framework provides a fully functional AP equipped with the physical layer and medium access control (MAC), a mobility model for the user device, and integration between LiFi and WiFi with a handover facility. Simulation results are produced to demonstrate the mobility and handover capabilities, and the performance gains from the LiFi-WiFi hybrid system in terms of packet delay, throughput, packet drop ratio (PDR), and fairness between users. The source code of the framework is made available for the use of the research community.

Cloud computing technologies are getting matured day by day. Revolutions in underlying software, virtualization and hardware technologies related to storage, processing and computing technologies has helped cloud computing service providers to win trust of concerned stake holders. However, the exponentially increasing demand of cloud based resources has made task of resource management and utilization more and more challenging. A novel load balancing technique in cloud computing environment is presented in this paper. The virtual machines are implemented on an open source cloud computing platform on open source operating system. A virtual machines’ priorities based load balancing approach presented here indicates improvement in overall waiting time for load balancing. The mechanism prioritizes load balancing on same priority level virtual machines or lower priority level virtual machines.

Library Automation

Purpose – The purpose of this study was to develop and update database of books in the International Management Institute Bhubaneswar. The study presents the status of automation in International Management Institute Bhubaneswar. A properly computerized library will help its user with quick services. Library automation refers to mechanization of library housekeeping operations predominantly by computerization. Implement automated system using New Gen Lib (NGL) library integrated open source software to carry out the functions of the circulation section more effectively to provide various search option to know the availability of books in the library and generate the list of books due by the particular member and also overdue charges. NGL is an integrated software system with required models for small to very large libraries. Being an open source any library wanted to go for automation for their library housekeeping operations can make use of this software. Design/methodology/approach – Open source is a software development model and a software distribution model. In this model, the source code of programs is made freely available with the software itself, so that anyone can see, change and distribute it provided they abide by the accompanying license. In this sense, open source is similar to peer review, which is used to strengthen the progress of scholarly communication. The open source software differs from the closed source or proprietary software, which may only be obtained by some form of payment, either by purchase or by leasing. The primary difference between the two is the freedom to modify the software. An open system is a design philosophy antithetical to solutions designed to be proprietary. The idea behind it is that institutions, such as libraries, can build a combination of components and deliver services that include several vendors' offerings. Thus, for instance, a library might use an integrated library system from one of the major vendors in combination with an open source product developed by another library or by itself to better meet its internal or users' requirements. Findings – NGL free software is constantly being updated, changed and customized to meet the library's needs. While all of this is fine and dandy, and sounds like the win-win solution for your library, there are still pitfalls and hurdles we will need to overcome. Hopefully, this article provides some introductory information as to how to wean your library off of traditional computing products and dive into the pool of open source resources available today. Libraries in the developing countries are able to support electronic access, digital libraries and resource sharing because they are able to use Open sources Software (OSS). Even libraries in well-developed countries are becoming more inclined toward OSS to improve their services. Originality/value – To develop and updated database of books and other online/printed resources of the International Management Institute Bhubaneswar. To implement automated system using NGL library integrated open sources software. To carry out the charging and discharging functions of the circulation section and Provide Various search options to know the availability of books in the library.

Software Platforms

Conversational software, or chatbots in popular parlance, has been in vogue amongst organizations for a few decades now. In sync with the trend, various libraries and knowledge resource centres have also adopted them within their technological fold, with an aim to provide improved services to patrons. The only bottleneck towards such implementation has been the dearth of open source conversational software platforms. The purpose of the paper is to conceptualize a library chatbot using a recently developed, artificial intelligence-powered open source conversational software platform named Rasa Stack. It introduces the essence of chatbot technology and their present day application in libraries, illustrates how the technical underpinnings of Rasa Stack can be leveraged to develop a library chatbot, and reflects on the potential future research in this direction.
