Efficient and secured framework for emergency communication in next generation networks supported hotspot regions

Abstract

Accommodating various devices and their connections in and beyond newlineFifth Generation (5G) networks obtain a lot of research attention from academia newlineand industry. The two important factors that stimulate next-generation wireless newlinenetworks to be integrated with the spectrum of several enabling technologies are, newline1) Providing energy-aware, cost-effective, and reliable communication, and 2) newlineEstablishing urgent communication networks, maximizing network coverage and newlineenhancing the efficiency of mobile devices either within the macro hotspot newlineregion or within the disaster region. For establishing effective emergency newlinecommunication, researchers suggest emerging technologies such as Device-to- newlineDevice (D2D), Light Fidelity (LiFi), and moving base stations. While in newlinedynamic environment, D2D may cause many critical challenges such as i) newlinechoosing a cluster head, ii) rediscovering a device, iii) inclusion of a new device newlineto the network, iv) configure cooperative sites, v) safety risks, vi) orchestrate newlineclusters, and vii) maintain vast heterogeneous clusters in a diverse channel. newlineSimilarly, LiFi works effectively in a dynamic environment but only at Line of newlineSight (LoS). newlineEven moving base stations have the capability to function with high newlinemobility, but unable to cross the paths of a transient network. It must be newlinesupported with offloading, maintaining global clock, discovery of path, coverage, newlinereliability and interoperability. In addition, it is imperative to provide stable newlineenergy in catastrophe situations because of battery restrictions newline
