5G Applications in Heterogeneous Network Issues and Challenges

Aspirations, challenges, and open issues for software-based 5G networks in extremely dense and heterogeneous scenarios

An upsurge of heterogeneous wireless devices and wide-ranging applications on extremely dense urban scenarios has led to challenging conditions that cannot be easily handled by 4G systems, such as the inefficient use of the frequency spectrum and the high energy consumption. In order to address those challenges, the 5G system design demands new architectures to cope with specific requirements, ...

Sandwich Generation Issues and Challenges

Today, with the increase in the elderly population and life expectancy, the need to use care services for this significant part of the population is increasing. Beliefs, cultures, and social norms among different ethnicities and races are vital in the extent and nature of care. Two types of care exist, informal and formal. According to statistics by the Secretariat of the National Council on Ag...

Policy Model for Sharing Network Slices in 5G Core Network

As mobile data traffic increases, and the number of services provided by the mobile network increases, service load flows as well, which requires changing in the principles, models, and strategies for media transmission streams serving to guarantee the given nature of giving a wide scope of services in Flexible and cost-effective.
