Emerging technologies provide a highly compatible platform for analyzing substantial data volumes relating to crowd man- agement. ese technologies are not only effective in providing remedial solutions but they are also cutting-edge, saving both time and money, and user-friendly. About twenty percent of the world’s Muslims are granted the ability to take part in religious observances on an annual basis. An in-depth analysis of the technologies and applications used in the Hajj and Umrah systems is required given the importance of utilizing and adapting technology to assist pilgrims performing the Hajj and Umrah. Both of these pilgrimages are considered acts of worship by Muslims. As a result, the services provided during Umrah and Hajj will be significantly enhanced if the numerous technological advancements that are evaluated in this paper are implemented. e majority of previous research is shown to revolve around artificial intelligence and embedded Internet of ings technologies in the paper, highlighting a gap in the research that should be filled by investigating the necessity of discussing and introducing immersive technologies. During the annual pilgrimage to Makkah, Saudi Arabia, several different technologies are utilized with the goal of enhancing the quality of services provided to pilgrims performing the Umrah and Hajj. is paper provides an analysis of these technologies. e findings of this paper point to new research directions as well as a more realistic and practical approach to improving services during Umrah and Hajj. 1. Introduction In recent years, the field of Internet of ings (IoT) tech- nologies has advanced significantly in a variety of industries and spheres of human activity. Today, technological ap- plications are essential to the growth and prosperity of people and nations across the globe and in sensitive services. Hajj is one of the five pillars of Islam and is an annual Islamic pilgrimage to the Saudi Arabian city of Makkah. Hajj is also referred to as a religious obligation that every physically fit and financially able adult Muslim must perform once every few years. When pilgrims from around the world reach the vicinity of the city of Makkah, they may be constrained by specific religious obligations [1]. In the context of Hajj, a large number of pilgrims must be efficiently managed due to a problem with crowd management that necessitates the use of technology [2]. e concept of crowd management is regarded as the most significant challenge facing Hajj and many other countries where large groups of people con- gregate. e procedure for controlling the flow of crowds has been described as an important and crucial concern, par- ticularly when a matter or an accident causes panic [3]. us, the concept of the emergence of technologies could aid in the development of crowd management solutions for actual disasters. In the past few years, the world has witnessed a variety of crowd-related disasters, including the deaths of thousands of people. For centuries, Hajj has been one of the most crowded places because it annually attracts millions of pilgrims to congregate in one location. e Kingdom of Saudi Arabia has been working to serve and manage the pilgrims, and Hajj aims to provide the best possible safety and security measures with regard to the facilities used for crowd control [2]. Utilizing modern technology in crowd management may be the optimal way to overcome the challenge and dispose of the potential problem. In the last 10 years, the Internet of ings (IoT) has created a primary Hindawi Applied Computational Intelligence and So Computing Volume 2022, Article ID 1919152, 10 pages https://doi.org/10.1155/2022/1919152
