whitepaper SEAD: Secure Efficient Distance Vector Routing for Mobile Wireless Ad Hoc Networks0000-00-00 Carnegie Mellon University
  An ad hoc network is a collection of wireless computers (nodes), communicating among themselves over possibly multihop paths, without the help of any infrastructure such as base stations or access points. This paper designs and evaluates the Secure Efficient Ad hoc Distance vector routing protocol (SEAD), a secure ad hoc network routing protocol based on the design of the Destination-Sequenced Distance-Vector routing protocol (DSDV). In order to support use with nodes of limited CPU processing capability, and to guard against Denial-of-Service (DoS) attacks in which an attacker attempts to cause other nodes to consume excess network bandwidth or processing time, it use efficient one-way hash functions and do not use asymmetric cryptographic operations in the protocol.

whitepaper A Short guide to a faster WAN2007-07-20 Quocirca Ltd
  Wide areas networks (WANs) are essential to the majority of businesses, connecting remote locations and individuals back to centralised IT resources. But as the network is expected to handle more bandwidth intensive applications such as voice and video it is essential to ensure the WAN usage is well managed - eliminating unwanted traffic and accelerating business content

whitepaper A Bandwidth-on-Demand System Case-Study Based on GN2 Project Experiences2007-07-16 GARR
  The JRA3 Activity of GN2 project is heading to implement a multi-domain, heterogeneous technologies bandwidth reservation system for end users. During the design and implementation efforts of the last two years, project participants have come across a set of problems and decisions that are common for reservation systems. Having in mind the specific project objectives, supported by the knowledge and experience from similar efforts around the world, the JRA3 team has been working to identify the most suitable, and flexible approaches for inter-domain Bandwidth-on-Demand (BoD) provisioning issues. This paper presents the assumptions and decisions made so far, their background, pros and cons, and their consequences for the further project development.

whitepaper TCP Prediction for Adaptive Applications2007-07-15 Deutsche Telekom
  Adaptive applications, such as real-time multimedia streaming applications, are increasingly using TCP as their underlying transport protocol. To adapt the content, an elastic application needs a prediction of the future available bandwidth. Unfortunately, the socket API does not allow an application to get information from the transport layer. Therefore, this paper proposes an approach where a monitor collects packet information from the network interface, creates a time series by sampling the packet information, and uses prediction models to assess the future available bandwidth.

whitepaper Bandwidth Provisioning in Infrastructure-Based Wireless Networks Employing Directional Antennas2007-07-10 Pennsylvania State University
  Motivated by the widespread proliferation of wireless networks employing directional antennas, the paper study the problem of provisioning bandwidth in such networks. Given a set of subscribers and one or more access points possessing directional antennas, the paper formalizes the problem of orienting these antennas in two fundamental settings; subscriber-centric, where the objective is to fairly allocate bandwidth among the subscribers; and provider-centric, where the objective is to maximize the revenue generated by satisfying the bandwidth requirements of subscribers. For both the problems, it first designs algorithms for a network with only one access point working under the assumption that the number of antennas does not exceed the number of non-interfering channels.

whitepaper Optimizing the ASC WAN: Evaluating Network Performance Tools for Comparing Transport Protocols2007-07-01 Sandia National Laboratories
  The Advanced Simulation & Computing Wide Area Network (ASC WAN), which is a high delay-bandwidth network connection between US Department of Energy National Laboratories, is constantly being examined and evaluated for efficiency. One of the current transport-layer protocols which is used, TCP, was developed for traffic demands which are different from that on the ASC WAN. The Stream Control Transport Protocol (SCTP), on the other hand, has shown characteristics which make it more appealing to networks such as these. Most important, before considering a replacement for TCP on any network, a testing tool that performs well against certain criteria needs to be found.

whitepaper Optimal Replica Placement in Tree Networks With QoS and Bandwidth Constraints and the Closest Allocation Policy2007-06-28 French National Institute for Research in Computer Science and Control
  This paper deals with the replica placement problem on fully homogeneous tree networks known as the Replica Placement optimization problem. The client requests are known beforehand, while the number and location of the servers are to be determined. The latter problem is investigated using the Closest access policy when adding QoS and bandwidth constraints. The paper proposes an optimal algorithm in two passes using dynamic programming.

whitepaper Performance Modeling of Network Coding in Epidemic Routing2007-06-11 Association for Computing Machinery
  Epidemic routing has been proposed to reduce the data transmission delay in opportunistic networks, in which data can be either replicated or network coded along the opportunistic multiple paths. This paper introduce an analytical framework to study the performance of network coding based epidemic routing, in comparison with replication based epidemic routing. With extensive simulations, the paper show that this model successfully characterizes these two protocols and demonstrates the superiority of network coding in opportunistic networks when bandwidth and node buffers are limited. Then the paper propose a priority variant of the network coding based protocol, which has the salient feature that the destination can decode a high priority subset of the data much earlier than it can decode any data without the priority scheme.
