An End-to-End QoS Framework for 4G Mobile Heterogeneous Environments
White Paper The framework integrates layer two and layer three handovers by exploiting minimal additions to existing IETF and IEEE standards. Next Generation Networks (NGN) will be based upon the "all IP" paradigm. [18 Jul 2008]
IP Bandwidth on Demand and Traffic Engineering Via Multi-Layer Transport Networks
White Paper This paper investigates the advantages of multi-layer methods of supplying moderate to high IP bandwidth either on demand for end users or for traffic engineering purposes over a shared, heterogeneous, wide area network infrastructure. [11 Jul 2008]
Achieving Loss Isolation for TCP Over Multiple Wireless Interfaces
White Paper When heterogeneous wireless networks overlap in coverage, a mobile terminal can use multiple wireless interfaces simultaneously to achieve higher bandwidth. A scheduling algorithm, Bandwidth Aggregation (BAG), suggests an approach to efficiently... [14 Jan 2008]
A Network Layer Approach to Enable TCP Over Multiple Interfaces
White Paper When heterogeneous wireless networks overlap in coverage, a mobile terminal can potentially use multiple wireless interfaces simultaneously. This paper motivates the advantages of simultaneous use of multiple interfaces and presents a network layer... [19 Dec 2007]
C-Snoop: Cross Layer Approach to Improving TCP Performance Over Wired and Wireless Networks
White Paper In heterogeneous wired and wireless networks, however, the high packet loss rate over wireless links can trigger unnecessary execution of TCP congestion control algorithms, resulting in performance degradation. [05 Dec 2007]
Combining Transport Layer and Link Layer Mechanisms for Transparent QoS Support of IP Based Applications
White Paper Providing IP services with QoS support in heterogeneous networks involving wired and wireless sections has been identified as a challenging task. The goal of this paper is to show how link level mechanisms can be enhanced by transport layer... [05 Dec 2007]
Investigating the Scaling Behaviour of Internet Flow Arrivals
White Paper The Internet is a highly heterogeneous complex system, linking more than 120 million host computers across more than 100000 networks. It is architectured in a series of layers, each of which relies on the next lower layer to execute more primitive... [05 Dec 2007]
Making Retransmission Delays in Wireless Links Friendlier to TCP
White Paper Heterogeneous communication networks with their variety of application demands, uncertain time-varying traffic load, and mixture of wired and wireless links pose several challenging problem in modeling and control. [05 Dec 2007]
Cross-Layer-Model Based Adaptive Resource Allocation for Statistical QoS Guarantees in Mobile Wireless Networks
White Paper The proposed scheme dynamically assigns power-levels and time-slots for heterogeneous real-time mobile users to satisfy the variation of statistical delay-bound QoS requirements. To achieve this goal, the paper applies Wu and Negi's effective... [31 Aug 2007]
Geometric Broadcast Protocol for Heterogeneous Sensor Networks
White Paper This paper presents Geometric Broadcast for Heterogeneous Sensor Networks (GBS), a novel broad-casting protocol for heterogeneous wireless sensor and actor networks. Therefore, reducing the energy consumption by optimizing broadcasting is a major... [23 Aug 2007]
Cross-Layer-Model Based Adaptive Resource Allocation for Statistical QoS Guarantees in Mobile Wireless Networks
White Paper The proposed scheme dynamically assigns power-levels and time-slots for heterogeneous real-time mobile users to satisfy the variation of statistical delay-bound QoS requirements. To achieve this goal, the paper applies Wu and Negi's effective... [10 Aug 2007]
A Framework for Querying Sensor Networks Using Mobile Devices
White Paper This will enable a heterogeneous design space that can offset the stringent resource and power constraints encountered in traditional static sensor networks by taking advantage of the more powerful mobile devices. [01 Aug 2007]
Adaptive Resource Allocation and Scheduling for Multiuser Packet-Based OFDM Networks
White Paper As it moves towards the next generation wireless communications systems featured by all IP-based protocols and heterogeneous traffic calls, new issues arise in designing resource management algorithms. [11 Apr 2007]
Physical Topology Discovery for Large Multi-Subnet Networks
White Paper This paper proposes the first complete algorithmic solution for discovering the physical topology of a large, heterogeneous Ethernet network comprising multiple subnets as well as (possibly) dumb or uncooperative network elements. [12 Dec 2006]
Topology Discovery in Heterogeneous IP Networks
White Paper This paper presents novel algorithms for discovering physical topology in heterogeneous (i.e.multi-vendor) IP networks. Earlier work has typically concentrated on either discovering logical (i.e.layer-3) topology, which implies that the... [06 Dec 2006]
