This document proposes a new MAC protocol for wireless access over TV white spaces that accounts for diverse user locations and spectrum-dependent channel rates to provide fair data rates and efficient utilization. The proposed MAC architecture supports multiple radios at the access point to address the fragmented and limited bandwidth of the available spectrum. Simulation results show throughput gains of 30-76% and reductions in collisions of up to 80% compared to a standard Wi-Fi MAC. A prototype implementation demonstrates the feasibility and robustness of the new design.

A Novel Resource Allocation Method For Multicasting Network Using Call Admiss...IJTET Journal
Abstract— WiMAX relay networks make resource allocation decisions once per frame. An IEEE 802.16j frame consists of a downlink sub frame and an uplink sub frame. This study focuses on the downlink multicast problems. The downlink sub frame can be divided into an access zone and a relay zone. In the access zone, the BS transmits the video data to its served RSs and SSs. In the relay zone, the RSs further relay the video data to their served SSs. To determine the data transmissions within each frame, the BS should make a scheduling decision at the beginning of each frame using an appropriate resource allocation scheme. WiMAX is generally used to reduce the delays and packet loss. It a wireless standard designed to provide data transfer. In this paper mainly focuses on implementing BGWA based algorithm in order to avoid unwanted intrusion occurrences in handoff time. The Mobile Motion Prediction algorithm generally keeps track of the positions of the mobile stations and their relevant connections. The task of motion prediction is to track the motion of the mobile station in different gateways. Then different prediction methods are applied according to the sensitivity of the range to gain high precision. CAC Approach can be used to the worldwide interoperability for microwave access (WiMAX) is a promising technology for last-mile Internet access, particularly in the areas where wired infrastructures are not available. Mainly this approach is used to transmitting the video/Audio sending from base station to relay station with transmitting or secretes code.

The performance of varied (QPSK) and (QAM) modulation techniques, by applying the (OPNET) simulator version 17.5. This work is finished in terms of the transmitted traffic and received traffic. Simulation result indicates that once nodes are moving by (SVC) code schema in (WiMAX). The result is an effective and attainable overall performance of (QPSK) which is better than (QAM) modulation technique.
Emerging Radio Technologies that are mmWave communications, Massive MIMO, Novel Waveforms and Multiple Access techniques etc. will provide ultra-high data rate traffic per user. However, only new Radio techniques implemented in lower layers of legacy networks could not guarantee the all 5G requirements, consequently the new network architecture along with new Radio technologies will emerge to fulfill all 5G requirements.

Satellite IP Trunking networks provide local networks with access to the internet (or any other type of network) from a remote access point to the backbone. Providing IP Trunking and Backbone services to ISPs and Telecom operators requires constant scrutinizing of the operational expenses due to a highly competitive market with razor- thin margins.

RESOURCE ALLOCATION ALGORITHMS FOR QOS OPTIMIZATION IN MOBILE WIMAX NETWORKSijwmn
WiMAX is based on the standard IEEE 802.16e-2009 for wireless access in Metropolitan Area Networks. It
is one of the solutions for 4G IP based wireless technology. WiMAX utilizes Orthogonal Frequency
Division Multiple Access which also supports Multicast and Broadcast Service with appropriate
Modulation and Coding Scheme. Presently, Scheduling and Resource allocation algorithm in Opportunistic
Layered Multicasting provides multicasting of layered video over mobile WiMAX to ensure better QoS.
Initially, the knowledge based allocation of subcarriers is used for scheduling. In addition, to reduce the
burst overhead, delay and jitter, SWIM (Swapping Min-Max) algorithm is utilized. Another promising
technology that can greatly improve the system performance by exploring the broadcasting nature of
wireless channels and the cooperation among multiple users is the Cooperative Multicast Scheduling
(CMS) technique. The simulation results show, Swapping Min-Max performs better with lesser number of
bursts, Zero jitter and with optimal throughput. The results with Cooperative Multicast Scheduling show
the enhanced throughput for each member in the Multicasting Scenario.

An agile and efficient mac for wireless access over tv whitespaces
1. An Agile and Efficient MAC for Wireless Access over TV Whitespaces
Abstract:
The FCC mandate of allowing TV Whitespaces for unlicensed access has
the potential for dramatic improvements in wireless access data rates. We
argue that an ideal MAC should account for diverse user-location and
spectrum dependent channel rates to provide fair data rates and efficient
utilization. Furthermore, due to limited tunable bandwidth of a radio and
fragmented spectrum, the AP should support multiple radios. We make
the following contributions by designing a MAC for wireless LAN access
over TV Whitespace. (i) We propose an architecture and beaconing
mechanism to enable such a MAC. Our MAC is an evolution of 802.11
MAC. (ii) We propose an algorithm that chooses the Whitespaces for the
different radios of the AP and assigns clients to the radios. Our algorithm
has provable guarantee and is near-optimal in many scenarios. (iii)
Extensive simulation over OMNET platform demonstrates the benefit of
our design over a frequency and client-location agnostic Wi-Fi-like MAC.
The typical throughput gain is 30-76 percent, whereas, the reduction in
collisions is up to 80 percent. (iv) We implemented a proof-of-concept
prototype (by modifying madWiFi drivers) that demonstrates feasibility of
our design, robustness to temporal variation of available spectrum, and
system throughput.
