Abstract: This paper mainly consists of the implementation of IEEE 802.16 and provides a comparative evaluation of the different traffic sources of TCP and CBR in WiMAX networks. TCP is a connection-oriented transport layer protocol. It provides reliable byte stream services for data applications. Its key features are reliability, flow control, connection management and congestion control. AODV is used to compare and demonstrate the performance of TCP and CBR traffic, typically implemented in mobile ad-hoc environments. And in it various parameters like packet delivery ratio and throughput have been explored with change of speed. And found that the use of transmission control protocols is capable of achieving data transmission reliability in wireless systems. Therefore, this research proposes that TCP performs better than other CBR traffic. The overall simulations have done in Network Simulator. Keywords: MANET, AODV, WIMAX, TCP, CBR, Performance Metrics, NS-2.
I. INTRODUCTION In recent years, due to the high demand for Internet access and cellular services, its demand has increased in which data can be sent anywhere without any wires. It has rapidly gained popularity as an alternative to last mile connections replacing broadband wireless access cable modems and DSL connections. Wi-Fi is a wireless local area network technology designed for home and small area implementation. Wi-Fi is able to provide ad-hoc network facilities at a low level, while it had many drawbacks such as speed, distance ... etc. This gap has been overcome with the help of WiMAX. Both of these are IEEE standard, one of them is IEEE 802.16 standard which is also known as Mobile WiMAX. Worldwide interoperability for microwave access forums promises to offer a large number of high data rates to a large number of users where broadband is not available. WiMAX promises to deliver the last mile of communications services via the Internet. It provides very high data throughput over long distances. The above mentioned advantages of the IEEE 802.16 wireless network create a platform to fully fill this standard with other wireless communication technologies such as Wi-Fi. The requirement from IEEE 802.16 is to provide QoS for all possible. IEEE 802.16 is likely to emerge as a recent technology to support integrated voice, video and animation data services for broadband wireless access, fixed, roaming, portable and fully mobile operations everywhere. An algorithm is needed to manage and distribute traffic flow. The AODV protocol is used for data transmission in this work. The objectives of this paper are to get accurate perception and finding the best behavior of the MANET reactive on demand routing protocols under mobility, scalability and heavy, medium and low traffic load. The rest of the paper begins the analysis of TCP and CBR traffic based performance under different network scenarios. The results show that the variation of speed with constant no of connections. Section II, III and IV AODV, Problem Statement, WIMAX. Section- V, VI and VII, Data traffic, Simulation Model, performance metrics are carried out to evaluate the effectiveness of the proposed scheme. And section VIII Simulation Results analysis last section discussed about conclusion and References.
