The objective of this research paper is to provide brief overview on simulative investigation on VOIP over WiMAX communication network for static environment. The mobile WiMAX (IEEE802. 16e) support VOIP traffic under different scenario, QOS, the system throughput, the packet delay,the signaling overhead,various design choices and performance analysis. This paper reports about the various VOIP ...

Fractional Frequency Reuse (FFR) is a key concept for increasing the spectral efficiency of OFDMA-based broadband wireless access systems such as Mobile WiMAX. One of the main challenges when using FFR is to decide which mobile stations are assigned to which FFR time zone within a WiMAX MAC frame, so that the frame resource utilization efficiency is maximized while meeting the QoS demands of al...

-The demand for wireless broadband services is growing rapidly. Mobile WiMAX is one of the most promising technologies for broadband wireless communication. It allows users to roam over the network under vehicular speeds. However since IEEE 802.16e standard for Mobile WiMAX defines only hard handover mandatory, Mobile WiMAX cannot transmit or receive packets during handover. Thus real-time pack...

Mobile WiMAX is a promising wireless technology approaching market deployment. Much discussion concentrate on whether mobile WiMAX will reach a tipping point and become 4G or not. As a pre-mobile WiMAX system is being delivered, we decided to set up a real life field trial and perform the most important measurements over the system setup. The system was delivered with 4th order diversity. In th...

This paper aims to The mobile WiMAX air interface adopts orthogonal frequency division multiple access (OFDMA) as multiple access technique for its uplink (UL) and downlink (DL) to improve the multipath performance. All OFDMA based networks, including mobile WiMAX experiences the problem of high peakto-average power ratio (PAPR). This thesis presents: Discrete-Cosine transform matrix (DCTM) pre...

Real-time peer-to-peer (P2P) streaming video traffic will constitute a significant proportion of future Internet traffic. With the availability of WiMAX, a large number of these peers will be ubiquitous and located on WiMAX based mobile nodes across the Internet. This chapter proposed a framework for providing quality of service (QoS) to the overlay P2P network over a WiMAX infrastructure. The ...

Many of the features of EPON and WiMAX are complementary. In [1] we proposed four basic architectures for the integration of EPON and WiMAX, which employs an EPON as a backhaul to interconnect multiple WiMAX base stations. The integration takes advantage of the high capacity of fibre communication as well as the mobile and non-line of sight (NLOS) features of wireless communication. In this art...

WiMAX—the Worldwide Interoperability for Microwave Access is a promising technology for offering high-speed data, video and multimedia services over mobile platform evolving toward all IP networks. The increasing demand of WiMAX for VoIP and high-speed multimedia is due to the simplicity of installation and cost reduction compared with the traditional wired DSL cable. The challenges to service ...

IEEE 802.16 Worldwide Interoperability for Microwave Access (WiMAX) is an emerging broadband wireless communication standard used as a model of transmission and high speed Internet access. 3G Long Term Evolution (LTE) is the leading standard for wireless communication of high-speed data for mobile users. In this report we compare the performance of voice and video applications over WiMAX and LT...

A link adaptation (LA) scheme for the downlink of mobile hotspot, which is supported by an IEEE 802.16e or mobile WiMAX network, is proposed. The mobile WiMAX uses orthogonal frequency division multiple access (OFDMA) in its physical layer. The main function of the LA scheme is to select an appropriate burst profile, which includes a multiple input multiple output (MIMO) transmission mode, modu...
