Abstract: Due to fast development of technology, future communication and transmission are totally depends upon wireless network. Wireless networking has become an important area of research in academic and industry. This thesis is provides the analysis of the two emerging broadband wireless technology Wi-Fi and WIMAX, both of this IEEE MAC standard. With emerging technologies and higher data rate requirements new ways of communications are being developed. In Main challenges of Wi-Fi is security, limited Area, lower rate of data speed etc... We have solved these challenges using WiMAX. In this thesis we have implemented WiMAX MAC/802.16 standard and compare with Wi-Fi MAC/802.11 using AODV routing scheme. and we have found from simulation experimental Analysis the behavior of the network And finally have evaluated their performances in terms of delay and load. And It has been observed that the performance of the WiMAX is better than the Wi-Fi. Keywords: MANET, AODV, Wi-Fi, WiMAX, NS-2.
I. INTRODUCTION Due to fast development of technology, future communication and transmission are totally depends upon wireless network. The wireless medium has limited bandwidth, higher packet error rate, and higher packet overheads that in total to limit the capacity of the network to offer guaranteed Quality of services. WiMAX system has been widely accepted as the next-generation high-speed wireless communication system for future broadband services due to the high capacity, large coverage, and strong QoS support it can provide. As one of the most well-known and commonly used protocols, Wireless Fidelity (WiFi) network is based on the IEEE 802.11 standard that is used specifically for local network access. In response to the increasing QoS challenge in wireless networks, researchers have made significant modifications in Wireless Fidelity (WiFi) in the legacy IEEE 802.11 standards is based on IEEE 802.16, the Worldwide Interoperability for Microwave Access (WiMAX) is a standard with similar principles that is used in mobile devices to support high speed, long-range information exchange. It has been observed that the main advantage of WiMAX over WiFi is that it is capable of covering larger areas along with having higher data rates. Now, Wi-Fi and WiMAX are two broadband technologies but these technologies may have few similarities, and they differ in the technical execution and ultimately their business case is very different. And depth knowledge about the WiFi and WiMAX technology and how it works and understand the problems about the WiFi and how to solved using WiMAX technology in maintaining and deployment. WiMAX is the upcoming wireless system which uses IEEE standard 802.16. By using WiMAX technology we can overcome the limitations of the existing Wi-Fi like short coverage area, lack of security and low data rate. In our thesis, initially we analyzed the basic concept of WiMAX and comparison with Wi-Fi using AODV routing scheme. The rest of the paper is organized as follows. In Section 2, we introduce overview of overview of AODV, Section 3 Wi-Fi and Next Sections presents a WiMAX for increase network efficiency, result and lastly discussed conclusion.
