Research Paper (postgraduate) from the year 2011 in the subject Computer Science - IT-Security, ( Middlesex University in London ), course: Telecommunication Engineering, language: English, abstract: Undeniably, networks have become very important techniques of exchanging information (data) in fast ways. (WIMAX) World Interoperability for Microwave Access is one of the greatest technologies in the communication area. WIMAX has been used widely in telecommunication for long distance communication. From this point, this paper will explore four important sections related to this technique. Firstly, it will discuss the performance conduct of the WIMAX as compared to that of Wi-Fi. Secondly, it will critically evaluate the current solutions for the security problems in WIMAX network. Thirdly, it will attempt to design a new method to improve the security performance of WIMAX network. Fourthly, it will provide a security system that can be applied in real life applications to support the security performance of WIMAX network.
