Admission Control and Service Differentiation Based QoS Provisioning for Mobile Ad Hoc Network 0000-00-00 Waseda University

Service differentiation is the key to today's Internet QoS. However the assumption of static network topology and stability of links make the direct application of DiffServ in mobile ad hoc networks unfeasible. This paper presents admission control and service differentiation mechanism that works only in network layer and does not require any feed back from other layer. It works with ad hoc routing protocol to perform required tasks and can be incorporated in any kind of reactive routing protocols for mobile ad hoc networks like AODV, DSR etc. Moreover it does not require maintaining any state information over the whole route.

Multi-Path Admission Control for Mobile Ad Hoc Networks 0000-00-00 University of California

As wireless networks become more prevalent, users will demand the same applications that are currently available in wired networks. Further, they will expect to receive a quality of service similar to that obtained in a wired network. Included in these applications are real-time applications such as voice over IP and multimedia streams. To enable the support of applications that require real-time communication in ad hoc networks, congestion must be prevented so that the needed quality of service can be provided. An admission control mechanism is an essential component of the quality of service solution.

A Priority-Based Distributed Call Admission Protocol for Multi-Hop Wireless Ad Hoc Networks 0000-00-00 University of California

Ad hoc networks have been proposed for a variety of applications where support for real time, multimedia services may be necessary. This requires that the network is able to offer service differentiation and Quality of Service (QoS) appropriate for the latency and jitter bounds needed to meet the real time constraint. This paper describes a design for realistic QoS support using a system approach that involves co-ordinated changes at the MAC and IP layers. At the MAC layer, the paper proposes a priority-based scheduling mechanism to provide service differentiation based on current channel status. The paper develops a priority-based delay model for the adaptive backoff scheme. The delay model allows each node to make local admission decisions.

Model-Based Resource Prediction for Multi-Hop Wireless Networks 0000-00-00 University of California

Ad hoc networks have been proposed for a variety of applications where support for real time, multimedia services may be necessary. This requires that the network is able to offer Quality of Service (QoS) appropriate for the latency and throughput bounds needed to meet the real time constraint. An important component for QoS provisioning is resource estimation and quality prediction. This paper describes a Model-Based Resource Prediction (MBRP) mechanism to support real time communication in multi-hop wireless networks. Specifically, it develops an analytical model for differentiated MAC scheduling protocols.

Leveraging Mobility to Improve Quality of Service in Mobile Networks 0000-00-00 University of California

Existing solutions for QoS-aware routing in mobile multi-hop networks attempt to discover a QoS satisfactory route for the user at the user's current location. If a suitable route is not available at the current location, the user is denied access. This approach does not take advantage of the special characteristics of mobile multi-hop networks. That is, users in these networks are mobile and their connectivity is dependent on their location and the locations of other users. By changing their location, users can alter their connectivity characteristics and potentially obtain better service from the network. This paper proposes enhancing QoS-aware routing protocols to take advantage of this characteristic.

HAWAII: A Domain-Based Approach for Supporting Mobility in Wide-Area Wireless Networks 0000-00-00 Alcatel-Lucent

Mobile-IP is the current standard for supporting macro-mobility of mobile hosts. However, in the case of micro-mobility support, there are several competing proposals. This paper presents the design, implementation, and performance evaluation of HAWAII: a domain-based approach for supporting mobility. HAWAII uses specialized path setup schemes which install host-based forwarding entries in specific routers to support intra-domain micro-mobility. These path setup schemes deliver excellent performance by reducing mobility related disruption to user applications. Also, mobile hosts retain their network address while moving within the domain, simplifying QoS support. Furthermore, reliability is achieved through maintaining soft-state forwarding entries for the mobile hosts and leveraging fault detection mechanisms built in existing intra-domain routing protocols.

QOS, QOE and Total Customer Experience 0000-00-00 Masergy

Business success requires productively and simply leveraging an increasingly rich menu of IP network-based Multimedia, Internet, Communications and Entertainment (MICE) capabilities. Due to the sophistication required to provide, support and manage MICE capabilities they are often purchased as services from a service provider. Because MICE services are critical to business success, organizations of all sizes are evolving to an enlightened, business-focused method of choosing network services and service providers called Total Customer Experience (TCE). This white paper, by James P. Cavanagh of The Consultant Registry, describes the evolution toward a TCE approach and the benefits and clarity that TCE brings to the marketplace.

Adaptive Quality of Service for a Mobile Ad Hoc Network 0000-00-00 University of California

This paper presents a QoS routing system for MANET supporting multiple traffic classes. The system takes into consideration clustering and channel allocation. Simulation experiments show that the algorithms are convergent. The system also yields a higher total throughput compared to the case in which every interface uses the same channel.

Allocating Resources to Multiple Antenna Mobile Nodes in Fading Wireless Ad-Hoc Networks With Temporally Correlated Loss 0000-00-00 University of California

Addressing the tradeoff between the Quality of Service (QoS) and consumed power is a critical issue for wireless ad-hoc networks. The loss observed in such networks is often temporally correlated. Multiple antenna systems utilizing space-time block codes are gaining increasing popularity as the result of being adopted by different wireless standards. This paper focuses on optimal resource allocation schemes for wireless ad-hoc networks with mobile nodes utilizing space-time block codes. Relying on adaptive modulation techniques for multiple antenna systems, this paper examines optimal schemes of maximizing throughput under power and loss constraints as well as minimizing transmission power under throughput and loss constraints.

A Shoelace-Based QoS Routing Protocol for Mobile Ad Hoc Networks Using Directional Antenna 2007-08-01 National Chung Cheng University

This paper proposes a new QoS routing protocol for Mobile Ad hoc NETwork (MANET) using directional antenna. The scheme offers a bandwidth-based routing protocol for QoS support in MANET using the concept of multi-path. The MAC sub-layer adopts the CDMA-over-TDMA channel model. The QoS on-demand routing protocol determines the end-to-end bandwidth calculation and bandwidth allocation from a source node to a destination node. The paths are combined with multiple cross links, called as shoelace, when the network bandwidth is strictly limited. Due to the directional antenna property, these cross links can simultaneously transmit data without any data interference.
