Adaptive Bandwidth Management Model for Wireless Mobile Ad-hoc Network
The quality of service (QoS) component in a mobile ad-hoc network has an active role in the current network scenario. In a dynamic mobile ad hoc network, ensuring optimum QoS with a scarce network resource is a significant challenge. To achieve QoS, it is essential to adopt some effective and efficient mechanisms. We have proposed an adaptive bandwidth manager model (ABMM) which uses a bandwidthsharing concept along with the flexible bandwidth reservation algorithm (FBRA) for an effective, quick and authentic data transfer. During real-time data transfer, to make communication effective, we make use of bandwidth-sharing network design problems and the concept of reserving bandwidth in high-performance networks. In our proposed model we are concentrating on the maximum utilization of resources, and using the scheduling concept to provide the minimum required bandwidth guarantee to QoS flows. Our goal is to reduce the delay in data transfer and enhance the throughput while properly utilizing the system resources. Our simulation result also shows that our model improves the network performance.

Regressive admission control enabled by real time qos measurements
We propose a novel regressive principle to Admission Control (AC) assisted by real-time passive QoS
monitoring. This measurement-based AC scheme acceptsflows by default, but based on the changes in the
network QoS, it makes regressive decisions on the possible flow rejection, thus bringing cognition to the
network path. TheREgressive Admission Control (REAC) system consists of three modules performing the
necessary tasks:QoS measurements, traffic identification, and the actual AC decision making and flow
control. There are two major advantages with this new scheme; (i) significant optimization of the
connection start-up phase, and (ii) continuous QoS knowledge of the accepted streams. In fact, the latter
combined with the REAC decisions can enable guaranteed QoS without requiring any QoS support from
the network. REAC was tested on a video streaming test bed and proved to have a timely and realistic
match between the network's QoS and the video quality.

Enhancing qo s and qoe in ims enabled next generation networks
Managing network complexity, accommodating greater numbers of subscribers, improving coverage to support data services (e.g. email, video, and music downloads), keeping up to speed with fast-changing technology, and driving maximum value from existing networks – all while reducing CapEX and OpEX and ensuring Quality of Service (QoS) for the network and Quality of Experience (QoE) for the user. These are just some of the pressing business issues faced by mobileservice providers, summarized by the demand to “achieve more, for less.” The ultimate goal of optimization techniques at the network and application layer is to ensure End-user perceived QoS. The next generation networks (NGN), a composite environment of proven telecommunications and Internet-oriented mechanisms have become generally recognized as the telecommunications environment of the future. However, the nature of the NGN environment presents several complex issues regarding quality assurance that have not existed in the legacy environments (e.g., multi-network, multi-vendor, and multi-operator IP-based telecommunications environment, distributed intelligence, third-party provisioning, fixed-wireless and mobile access, etc.). In this Research Paper, a service aware policy-based approach to NGN quality assurance is presented, taking into account both perceptual quality of experience and technologydependant quality of service issues. The respective procedures, entities, mechanisms, and profiles are discussed. The purpose of the presented approach is in research, development, and discussion of pursuing the end-to-end controllability of the quality of the multimedia NGN-based communications in an environment that is best effort in its nature and promotes end user’s access agnosticism, service agility, and global mobility
Wireless Networks Performance Monitoring Based on Passive-active Quality of S...
Monitoring of the performance of wireless network is of vital importance for both users and the service provider which should be accurate, simple and fast enough to reflect the network performance in a timely manner. The aim of this paper is to develop an approach which can infer the performance of wireless ad hoc networks based on Quality of service (QoS) parameters assessment. The developed method considers the QoS requirements of multimedia applications transmitted over these kind of networks. This approach is based on the ideas of combination of both active and passive measurement methods. This approach uses an in-service measurement method in which the QoS parameters of the actual application (user) are estimated by means of dedicated monitoring packets (probes). Afterwards, these parameters are combined to produce and assess the application’s overall QoS using the fuzzy logic assessment and based on the measured QoS parameters estimated using the probe traffic. The active scheme is used to generate monitoring probe packets which are inserted between blocks of target application packets at regular intervals. While the passive monitoring is utilized to act as a traffic meter which performs as a counter of user packets (and bytes) that belong to the application (user) traffic flow that is subjected to monitoring. After simulating the developed technique, it offered a good estimation for the delay, throughput, packet losses and the overall QoS when using different probe rates.

Abstract: Traffic is the chief puzzle problem in which every country faces to elaborate sending a
number of packets throughout the world. This paper proposes a new speculation for distributed traffic
management by availing the presumption of fuzzy logic. The routers are established by using an
IntelRate Controllers to manage the traffic congestion in the networks dynamically. Fuzzy logic is used
to previse the maximum allowable sending rate by observing the queue size of router. The network
traffic control protocol is unique to estimate the network parameter which involves link latency,
bottleneck bandwidth or packet loss rate in order to compute the allowed source sending rate. The fuzzy
logic based controller can measure queue size directly, it neglects various potential performance issues
arising due to parameter estimation as reduce consumption of computation and memory resource in
router. A network parameter, the queue size can be viewed accurately and if action should be taken to
regulate the source sending rate and it increases the resilience of the network to traffic congestion.
Using the fuzzy logic technique, QoS (Quality of Service) can achieve better performance than the
existing protocol that depends on the estimation of network parameter, to make the network more
adaptive for current traffic conditions.

Wireless Sensor Network Using Six Sigma Multi Hop Routing
Abstract: The most significant problem in the design of wireless sensor networks is to coordinate the sensors with dynamism into a wireless communication network and route sensed data to the base station. The energy efficiency is the most important key point of the network routing designing. This paper presents the efficient multi hop routing algorithm to extend the lifetime of sensor networks and focuses by employing six sigma principles to obtain the Quality of Service.

Proposed wfq based dynamic bandwidth
In this project, we proposed a framework to support heterogenous traffic with different QoS demand in
WiMAX. This framework dynamically changes the bandwidth allocation (BA) for ongoing and new arrival
connections based on network condition and service demand. The objective is to efficiently use the
available bandwidth and provide QoS support in a fair manner. Dynamic allocation of spectrum prior to
transmission can mitigate the starvation problem of Non Real time application. The WFQ based dynamic
bandwidth allocation framework uses architecture that has packet scheduler scheme (PS), call admission
policy and a dynamic bandwidth allocation mechanism. By the simulation result we have showed that this
architecture could provide QoS support by being fair to all classes of services.

This work investigates the QoS provisioning of various traffic classes on an SDN-enabled network. We
propose and implement the class-based adaptive QoS control scheme on SDN-enabled network for various
traffic classes, namely VoIP, Video Streaming and File Transfer. The effectiveness of our proposed scheme
is validated by simulation using Mininet and Ryu controller. The procedure to create the simulation
platform and all details relevant to all software used are described step-by-step in detail. The main
performance evaluation metric is the Maximum Number of Traffic Flows admittable with QoS while
Average Throughput, Latency, Jitter, and Packet Loss Rate are maintained at the comparable level of the
existing work in the literature called JMABC [11]. Our simulation results are illustrated with 95%
confidence interval. According to the simulation results, it is obvious that our proposed class-based
adaptive QoS control scheme adopting the optimization technique significantly outperforms the existing
similar QoS provision scheme in terms of the maximum number of the high priority traffic flows (VoIP)
admittable with QoS while the other evaluation metrics are maintained at the same level.

ANALYTIC HIERARCHY PROCESS FOR QOS EVALUATION OF MOBILE DATA NETWORKS
The widespread demand for data applications over mobile networks requires that service providers guarantee a well-defined quality of service (QoS) for subscribers. Evaluating the QoS provided by service providers within a geographical area to determine which network provides the best QoS is a challenging task. The complex nature of mobile networks with multi-criteria and conflicting factors makes good decision making difficult. This paper presents a measurement-based method called Analytic Hierarchy Process (AHP) for evaluating QoS in application-specific and user-centric data on 3G mobile networks. The evaluation problem is formulated as a multi-criteria decision problem. Latency, jitter, data loss, and throughput are the parameters collected as criteria in drive testing over the mobile network. Decision matrix is applied to solve the problem by reaching a final ranking of the network based on the collected measured values of the problem parameters. A case study of 3G mobile networks in Uyo metropolis is used to show how this approach can be effective in ranking the QoS in data applications to determine which network provides the best QoS based on users’ perception of quality. The implemented results in Java indicate that Etisalat network is the alternative that offers the best QoS for web browsing application based on measured criteria. This is followed by Airtel and then MTN, while Glo is ranked least. The result provides useful information to decision makers for performance improvement on service quality.

arising due to parameter estimation as reduce consumption of computation and memory resource in
router. A network parameter, the queue size can be viewed accurately and if action should be taken to
regulate the source sending rate and it increases the resilience of the network to traffic congestion.
Using the fuzzy logic technique, QoS (Quality of Service) can achieve better performance than the
existing protocol that depends on the estimation of network parameter, to make the network more
adaptive for current traffic conditions

Proposed wfq based dynamic bandwidth
In this project, we proposed a framework to support heterogenous traffic with different QoS demand in
WiMAX. This framework dynamically changes the bandwidth allocation (BA) for ongoing and new arrival
connections based on network condition and service demand. The objective is to efficiently use the
available bandwidth and provide QoS support in a fair manner. Dynamic allocation of spectrum prior to
transmission can mitigate the starvation problem of Non Real time application. The WFQ based dynamic
bandwidth allocation framework uses architecture that has packet scheduler scheme (PS), call admission
policy and a dynamic bandwidth allocation mechanism. By the simulation result we have showed that this
architecture could provide QoS support by being fair to all classes of services.

This work investigates the QoS provisioning of various traffic classes on an SDN-enabled network. We
propose and implement the class-based adaptive QoS control scheme on SDN-enabled network for various
traffic classes, namely VoIP, Video Streaming and File Transfer. The effectiveness of our proposed scheme
is validated by simulation using Mininet and Ryu controller. The procedure to create the simulation
platform and all details relevant to all software used are described step-by-step in detail. The main
performance evaluation metric is the Maximum Number of Traffic Flows admittable with QoS while
Average Throughput, Latency, Jitter, and Packet Loss Rate are maintained at the comparable level of the
existing work in the literature called JMABC [11]. Our simulation results are illustrated with 95%
confidence interval. According to the simulation results, it is obvious that our proposed class-based
adaptive QoS control scheme adopting the optimization technique significantly outperforms the existing
similar QoS provision scheme in terms of the maximum number of the high priority traffic flows (VoIP)
admittable with QoS while the other evaluation metrics are maintained at the same level.

ANALYTIC HIERARCHY PROCESS FOR QOS EVALUATION OF MOBILE DATA NETWORKS
The widespread demand for data applications over mobile networks requires that service providers guarantee a well-defined quality of service (QoS) for subscribers. Evaluating the QoS provided by service providers within a geographical area to determine which network provides the best QoS is a challenging task. The complex nature of mobile networks with multi-criteria and conflicting factors makes good decision making difficult. This paper presents a measurement-based method called Analytic Hierarchy Process (AHP) for evaluating QoS in application-specific and user-centric data on 3G mobile networks. The evaluation problem is formulated as a multi-criteria decision problem. Latency, jitter, data loss, and throughput are the parameters collected as criteria in drive testing over the mobile network. Decision matrix is applied to solve the problem by reaching a final ranking of the network based on the collected measured values of the problem parameters. A case study of 3G mobile networks in Uyo metropolis is used to show how this approach can be effective in ranking the QoS in data applications to determine which network provides the best QoS based on users’ perception of quality. The implemented results in Java indicate that Etisalat network is the alternative that offers the best QoS for web browsing application based on measured criteria. This is followed by Airtel and then MTN, while Glo is ranked least. The result provides useful information to decision makers for performance improvement on service quality.
Dynamic Quality of Service Stability Based Multicast Routing Protocol for MAN...
Mobile ad hoc networking does not possess any fixed infrastructure and hence, stable routing is
the major problem. The mobility nature of MANET’s node facilitates rediscovery of a new path
to organizing a routing. In order to intensify the Quality of Service and routing stability in
MANET, we propose a Dynamic Quality of service Stability based Multicast Routing Protocol
by modifying the Cuckoo Search Algorithm through a modernizing mechanism which is derived
from the differential evolution algorithm. Tuned CSA is a combined feature of CSA and DE
algorithms. Periodically, each node in the network creates neighbour stability and QoS
database at every node by calculating the parameters like node and link stability factor,
bandwidth availability, and delays. Finally, multicast path constructs route request and route
reply packets, stability information and performing route maintenance

- 2. Research Motivation The set of constraints such as bandwidth, delay and packet delivery ratio is termed as QoS in Manet These QoS metrics should be supported for transmitting a packet of data in order to support application requirements Problem Definition Bandwidth estimation is a mechanism to determine the data rate available on a network route The maximum possible data rate in absence of competing flows is termed as bandwidth. Available bandwidth is the maximum attainable data rate for current flows 2
- 3. Aim and Objectives Select and use a route that will satisfy the application’s bandwidth requirement. Provide an effective, scalable on demand routing protocol so that end-to-end communication with QoS requirement can be maintained. We aim at the development of routing protocols that provides Soft QoS or better than best-effort service, rather than guaranteed hard QoS. Implement bandwidth estimation techniques. Implement route maintenance mechanism. To integrate bandwidth estimation technique and admission control scheme into on demand routing protocol with data rate as the QoS requirement. Simulate QoS on demand routing protocol using network simulator (NS-2.35), Ubuntu2 12.04 OS or on Windows7 using Cygwin as linux environment. 3
- 4. Research Methodology The beginning stage of research is concentrated on review of literature, books, relevant research papers progress of IEEE task groups. Different routing protocols, MAC protocols and cross layer approach were studied. During this phase different routing protocols, passive bandwidth estimation techniques, MAC protocols, hidden and exposed node problem, radio propagation model were examined. Review of literature was done by comparing the reactive QoS aware routing protocols. The main difference involves the techniques for estimation of bandwidth and admission control schemes. In the final phase development of routing protocols based on proposed bandwidth estimation techniques, admission control and route repair mechanisms have been implemented in order to analyze them for QoS constraint included in this research DCMAC was also implemented based on channel partition The proposed methods and protocols are implemented and analyzed using NS- 2.35 4
