Data offloading schemes using device to device communication for enhancing the performance of next generation networks

Abstract

A Next Generation Network (NGN) is an all-IP packet based network that supports both voice telephony as well as data. NGN supports ubiquitous mobility of the users, with greater speeds, throughout the length and breadth of the physical world. The International Telecommunication Union (ITU) defined an NGN as, quotA packet-based network able to provide services including Telecommunication Services and able to make use of multiple broadband, Quality of Service (QoS) enabled transport technologies and in which service-related functions are independent from underlying transport-related technologies. It offers unrestricted access for users to different service providers. It supports generalized mobility which will allow consistent and ubiquitous provision of services to usersquot. The migration to NGN reduces network and operational complexity resulting in better and more reliable services. It engages a meshed core, having in-built intelligence that provides scalability, throughput and enhanced QoS. NGN offers various benefits both for the end users and the service providers. Fifth-generation (5G) cellular network is the next generation of mobile broadband communication that augments the existing fourth-generation (4G) LTE networks. newlineIn telecommunications, 5G is the standard for broadband cellular networks that is expected to provide faster data speeds, greater capacity, better coverage and signaling, lower latency, and appreciably enhanced spectral efficiency. Device-to-device (D2D) communication is an application envisioned for 5G which allows the users to directly communicate with each other without involving the central communicating authority. The 5G cellular networks, with D2D communication enabled within, have two types of communication scenarios. newline newline
