Performance Analysis of Mobile WiMAX Networks on Various Routing Protocols Using Strict Priority and Weighted Round Robin Scheduling Algorithm on CBR Traffic
Abstract: MobileWiMAX (Worldwide Interoperability Microwave Access) is a wireless system based on the IEEE 802.16e standard and it has emerged as the strongest contender for broadband wireless technology with promises to offer guaranteed Quality of Service (QoS). It offers support high mobility in WiMAX Networks. This paper presents a comparative performance analysis of Mobile WiMAX Networks AODV, DSR and OLSR routing protocols using Strict Priority and Weighted Round Robin Scheduling Algorithm …

PAPR Reduction for Single Carrier-FDMA using Pilot Sequence Techniques
Abstract: SC-FDMA (Single carrier-Frequency Division Multiple Access) with lower PAPR (Peak-to-Average Power Ratio) than OFDMA (Orthogonal Frequency Division Multiple Access) is an attractive alternative to OFDMA. SC-FDMA also possesses basic advantages of OFDM. The 3rd generation partnership project (3GPP) long term evolution (LTE) standard has adopted orthogonal frequency division multiplexing access (OFDMA) in downlink and single carrier frequency division multiple access (SCFDMA) scheme for the uplink transmissions. In this paper, we …

Performance Evaluation of 5G transmission system and Simulation Modeling
Abstract: Orthogonal multiple access (OFDMA) is a very important technology for the fifth generation (5G) wireless communication networks to provide the need of the flexible demands of users on lower latency rate, high level of reliability, good amount of connectivity, large fairness, and high data throughput. The key idea behind MIMO based 5G networks are to provide multiple users in common resource block. The MIMO OFDM principle is the main framework …

Integrated Networks: A Survey
Abstract: AbstractUniversal Mobile Telecommunication System (UMTS) networks are solution for high speed voice and internet services with ubiquitous coverage. Ericsson Mobility Report (EMR) has claimed that subscriptions of UMTS/HSPA were 2.1 billion in 2015 and predicted that these are expected to reach 3.1 billion by the end of 2021 [1–3]. They support 384 kbps maximum data rate in downlink and 128 kbps data rate in uplink over a 5 km typical …

Overview of WiMAX Technology
Abstract: WiMAX is a wireless communications standard designed to provide 30 to 40 megabit-per-sec data rates, with the 2011 update providing up to 1 Gbit/s for fixed stations. WiMAX can provide at-home or mobile internet access across whole cities or countries. In many cases this has resulted in competition in markets which typically only had access through an existing incumbent DSL (or similar) operator. Additionally, given the relatively low costs associated …

A Review of WIMAX and Various Technology
Abstract: In today’s world a large number of wireless transmission technologies exist. These technologies are distributed over different network families depending upon the networks scale such as PAN, WLAN, WMAN and WAN. As the demand for data transmission with higher data rate changed, so as the focus on the development of wireless network is changed. Technologies that promise to deliver higher data rate are attracting more and more vendors and operators …
