scholarly journals Resource Sharing for Granted & Grant-free Demands in 5G for Non-orthogonal Multiple Access

In the present days we observed a drastic change in the usage of mobile internet as well as advancements in Internet of things. With this advancements in mobile communications as well as IOT, the present generation mobile communication i.e. 4G technology is considered to be not sufficient to reach to the needs of common people, therefore the upcoming generation 5G needs in a frame way to face to ultra huge network capacity & massive wireless connectivity. A major hopeful technology which has the capacity for enabling different user equipments, sharing interweaving wireless resources in 5G is named as Non Orthogonal multiple Access (NOMA) technology, where most of the industrialists & academicians are doing research in recent years To establish good Quality of Service (QoS) & also to obtain low access latency as well as overhead signaling NOMA must compulsorily support two kinds of approaches: i) Scheduling approach ii)Random approach. The major challenge we observe in these two kinds of approach is how efficiently we obtain simultaneous support. Here we are proposing an approach for combining the granted & grant free demands which works on the principle of allowing the approaches to share the same resources simultaneously. We are proposing heuristic resource algorithm which improve capacity of network & user connectivity of NOMA in 5G networking

Today, with the need of connecting information anytime, anywhere, especially mobile Internet and Internet of Things (IoT), this has set three important  requirements:solving the number of connections, increasing the speed of access  and higher security than current networks. The ITU-R team has developed  contents that related to the technical specifications of the 5th generation (5G) mobile communication system called IMT-2020. In order to address one of the  three major requirements of network operators, which is high availability connectivity, non-orthogonal multiple access technologies (NOMA) have been used to solve the problem. In contrast to orthogonal multi-access technology, NOMA serves a large number of users due to the non-orthogonal resource allocation. This article will introduce NOMA techniques and standards for peak data rates, user experience, bandwidth, reliability, latency, transmission capacity. . .

Mobile communication system is designed to provide reliable communication with more number of services and with low cost among multiple users. Due to limited frequency spectrum and resources, mobile communication requires more development in case of both establishing communication and maintenance in service quality. To fulfill these requirements, 5G mobile communication is being developed to provide high quality reliable communication and quality of service, by using beamforming model. As the trend of next generation mobile communication, 3D directional transmission is considered to give enhanced coverage model and reusability of frequency. Phase arrayed antenna is used in this beamforming model to give orthogonal communication among users. In this paper, a new modeling of beamforming is applied to give a new dimension by considering altitude with potential field strategy. Here phase arrayed antenna is replaced by 3-D smart antenna to improve the performance of 5G mobile communications. Performance evaluation outcomes 3D beamforming leads 2D beamforming in terms of communication delay, and uplink downlink throughput.

The performance of antenna has the conclusive influence to the performance of mobile communication terminal; one excellent-performance antenna can improve the communication quality of communication device greatly. With the developing of broadband wireless communication technology, the fourth generation mobile communication technology has advanced day after day, and will turn into practical soon. This article aim at the demand of the fourth generation mobile communication technologys standard of TD-LTE, combined with the fractal technology, photonic crystal texture and top loading technique, designing a fractal photonic crystal top loading antenna which can work in 2.6GHz frequency band, and make simulate analysis to the performance of antenna and make the sample of antenna to test. The result from simulation and test shows this antenna has a low return loss and the work bandwidth is big, which is suitable for the fourth generation mobile communications TD-LTE system.

Mesh Networks are employed in various applications despite issues relevant to interference and network capacity. These networks also impose delay in routing and reconfiguration. Traditionally, TDMA and FDMA techniques have been used in these networks. This paper proposes wideband code division multiple access (WCDMA) technique for enabling maximum power transfer, low energy consumption, interference free and plug-and-play feature enabling easy implementation of the technology. The spatial configuration and node count bounds are stated ensuring continuous satisfaction of quality of service by the communication link. Additionally, dynamic parallel orthogonal transmission and turbo coding schemes are used in combination to improve the efficiency of the network even for large hop counts.

Abstract With the continuous development of society and economy, the development and application of mobile communications have become more and more popular, and more people have begun to use mobile devices for office, study and life. The quality of mobile communications network signals directly affects people’s experience of use. The scope of actual application has gradually increased with the renewal of the technology itself. Based on the random walk model, this paper constructs a mobile communication data optimization plan. Through data storage, transmission delay, and information total control, the optimization form of wireless network mobile communication data transmission performance is studied. Practice shows that this scheme can effectively improve communication quality and transmission efficiency.

Digital libraries, designed to serve people and their information needs in the same way as traditional libraries, present distinct advantages over brick and mortar facilities: elimination of physical boundaries, round-the-clock access to information, multiple access points, networking abilities, and extended search functions. As a result, they should be especially well-suited for the disables. However, minorities, those affected by lower income and education status, persons living in rural areas, the physically challanged, and developing countries as a whole consistently suffer from a lack of accessibility to digital libraries. This paper evaluates the effectiveness and relevance of digital libraries currently in place and discusses what could and should be done to improve accessibility to digital libraries for under-graduate students.

The preconditions of storage pre-schedule and real-time schedule management are wireless access and mobility support technology in aluminum profile logistic, which is vital for the automated storage/retrieval system(AS/RS) and logistics processes, such as intelligent warehousing and shipment. Understandings characters of the current wireless access technologies, applicability of networking mobility schemes, and their cooperation or compatibility with the Internet of things, decide the AS/RS and logistics structure and its whole efficiency. So the relational technologies and schemes are introduced in this paper from bottom to top according to Open System Interconnect seven layers protocols. It reveals that integration of multi-technologies was widely adopted in project implementation, which can be helpful to achieve high quality of mobile Internet access with lesser costs. Moreover, the feasibility of handover simplification and quality of service construction imply the success of schemes in design. Finally the strategic impact factors of the networking mobility support technology for AS/RS and logistics are concluded as overlapping coverage network optimization, delay tolerant network, and quality of service system based on user behavior.
