Abstract: Worldwide interoperability for Microwave Access (WiMAX) is a telecommunications protocol that provides fixed and mobile internet access. In addition, WiMAX can provide mobile wireless broadband access without the requirement for direct line-of-sight with a base station. In contrast with other wireless networks, WiMAX can provide high broadband speed, large coverage area, multiple bands and support for multimedia. However, a serious problem, the broadcast storm, needs to be addressed due in part to excessive communications from mobile devices, such as file, audio and video sharing. Therefore, a three-layer-based WiMAX network topology is proposed to reduce packet collisions and to enhance performance of communication efficiently. Furthermore, the stability and expansibility of the WiMAX topology can be improved.

Keywords: distribution systems; WiMAX; worldwide interoperability for microwave access; broadcast storm; performance enhancement; three layer topology; clustering; mobile communications; internet access; wireless networks; packet collisions.
