- Bandwidth Allocation and Session Scheduling Using SIP
- Session Initiation Protocol SIP is a new signaling protocol designed to establish multimedia sessions in telecommunication networks. This paper suggests the extension of SIP functionalities to coordinate QoS mechanisms deployed in IP networks, and especially in DiffServ domain. Indeed, the interaction between small and big TCP sessions may have dramatic...

- Joint Allocation of Subcarriers and Transmit Powers in a Multiuser OFDM Cellular Network
- This paper considers the problem of joint bandwidth subcarriers and power allocation for the downlink of a multi-user multi-cell OFDM cellular network. This resource allocation problem is formulated as a power minimization problem, subject to meeting the target rates of all users in the network. The authors develop a distributed...

- A Shoelace-Based QoS Routing Protocol for Mobile Ad Hoc Networks Using Directional Antenna
- 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...

- Service Differentiation With MPLS
- Offering Quality of Service QoS based on the concept of Differentiated Services has been an important recent concern. This paper describes two kinds of traffic engineering techniques for implementing differentiated services based on MultiProtocol Label Switching MPLS Constraint based Routing (CR-LDP). Both use dynamic bandwidth allocation schemes and are compared...

- Optimal Bandwidth Allocation for Dynamically Priced Network Services
- The paper has proposed the use of dynamically priced network services to provide QoS guarantees within a network. End-to-end QoS can be achieved by using several of these services, perhaps from different ISPs. This paper considers the problem of determining the bandwidth to allocate each service in order to maximize...

- Multi-Bid Auctions for Bandwidth Allocation in Communication Networks
- This paper designs a bandwidth pricing mechanism that solves congestion problems in communication networks. The scheme is based on second-price auctions, which are known to be incentive compatible when a single indivisible item is to be sold (users have no interest to lie about the price they are willing to...

- Efficient Algorithms for Shared Backup Allocation in Networks With Partial Information
- This paper studies algorithms for establishing reliable connections with bandwidth guarantees in communication networks. In the normal mode of operation, each connection uses a primary path to deliver packets from the source to the destination. To ensure continuous operation in the event of an edge failure, each connection uses a...

- Intelligent Routing and Bandwidth Allocation in Wireless Networks
- Sensor networks and satellite constellations face a number of challenges for reliable and robust communications. Increasingly heterogeneous nodes and a multitude of new emerging Earth science applications put additional restrictions on throughput and delay requirements. These problems are further aggravated by energy and bandwidth constraints on the network nodes. Quality...

- Energy-Efficient MAC-PHY Resource Management With Guaranteed QoS in Wireless OFDM Networks
- Most of the current resource management algorithms are confined to a single layer of the network protocol stack, which leads to an inferior system performance. This paper proposes a joint MAC-PHY layer resource allocation algorithm. The proposed algorithm jointly optimizes the bandwidth and power allocation through an integrated design of...

- Credit Transfer Within Market-Based Resource Allocation Infrastructure
- Credit transfer protocols are being designed and implemented in market-based resource allocation infrastructures. The design details of these protocols determine the access-control policies that can be expressed and the trading patterns that can be supported. A protocol that enables fine grained manipulation of ownership authorities can support a wider range...

- A Practical Cross-Layer Mechanism for Fairness in 802.11 Networks
- Since wireless networks are more sensitive to variations in bandwidth and environmental interference than wired networks, most networks support a number of transmission rates that have different error and bandwidth properties. Access points can communicate with multiple clients running at different rates, but this leads to unfair bandwidth allocation. If...
