Mobile WiMAX is a broadband wireless solution that enables convergence of mobile and fixed broadband network through a common wide area broadband radio access technology and flexible network architecture.Performance evaluation of mobile WiMAX under varying channel is one of the convincing research interest.Most of the existing works,based on performance evaluation under channel condition are limited...
The challenge of providing seamless services to the end users moving from one network area to another has become a critical issue for the operators to focus on. Intersystem handover can be a solution whilst to maintain the continuation of an on-going session, IP management is a key issue. Henceforth, to resolve the intersystem handover, both application layer and network layer should be the points...
The IEEE 802.16/802.16e provides powerful tools in order to achieve different QoS constraints. The MAC layer defined five scheduling service types to provide QoS differentiation for different types of applications. In this paper, we investigate the performance of the scheduling schemes deployed in the OPNET modeler by considering VoIP, video conferencing and non-real-time services. We further investigate...
