Resource allocation in IEEE 802.16e mobile WiMAX networks: Survey

WiMAX (Worldwide Interoperability for Microwave Access) provides Internet access across the and have a wide range of services. It has been observed many researchers working on quality of services, applications and resource allocation. WiMAX networks incorporate several Quality of Services (QoS) mechanisms for guaranteed services for data, voice and video. The problem of assuring QoS is that how to allocate available resources. For resource allocation, what are the parameters to be define because the IEEE standard does not include any scheduling mechanism. It has become an important problem to solve more efficiently for the manufacturer to design the equipment, which should handle the resources optimum and efficient way. The paper discusses the key issues and design factor to be considered for the resource allocation. We also present the resource allocation techniques proposed ideas. We classify the proposed channel condition based hybrid mechanism. The goal of this study is to elaborate the proposed techniques, which are used for resource allocation.
