ABSTRACT
Wireless technology plays a dominant role in today’s tremendous demand for mobile user communication. Therefore, improving its ability to provide higher data rates and better quality of services (QoSs) is an urgent requirement. Al-Rubaye and Cosmas [1] highlighted the potential of integrating the cellular communication system with the Internet Protocol (IP) technology in a long-term evolution (LTE) network. The main objective is to provide a seamless and high data-rate connection with an efcient cost for global roaming and user-customized personal services. The ongoing 4G cellular network deployment involves three accessible concepts: to apply the new techniques such as interchanging the interoperability microwave access (WiMAX) backbone station with the LTE network to increase the cell capacity; to utilize the recongurable technologies, such as the cognitive radio (CR) and advanced antenna systems, to enhance the spectral efciencies; and to design a new network architecture for the mobile networks that boosts the capability to provide a seamless and robust connection. The integration of at least two of these concepts will contribute to the new generation of the cellular network that can be deployed to manage and handle the huge demand of high data trafc, while accomplishing the requirements of seamless mobility for various corresponding technologies.
