Geometric Broadcast Protocol for Heterogeneous Sensor Networks
White Paper GBS is scalable to the change in network size, node type, node density and topology. While broadcasting is a very energy expensive protocol, it is also widely used as a building block for a variety of other network layer protocols. [09 Aug 2008]
A Network Management Architecture for Robust Packet Routing in Mesh Optical Access Networks
White Paper The architecture can be utilized with an arbitrary, link-redundant mesh network (node-redundancy is necessary only to handle all node failures), and assumes neither the use of a star topology nor the ability to embed such a topology within the... [18 Jul 2008]
QoS Topology Control in Ad Hoc Wireless Networks
White Paper Given a set of nodes in a plane, end-to-end traffic demands and delay bounds between node pairs, the problem is to find a network topology that can meet the QoS requirements and the maximum transmitting power of nodes is minimized. [18 Jul 2008]
A Review of Traffic Grooming in WDM Optical Networks: Architectures and Challenges
White Paper Most previous research on traffic grooming is mainly based on the ring network topology. Various network and node architectures for different traffic-grooming scenarios are compared and discussed. The network performance is now mainly limited by... [18 Jul 2008]
Energy-Aware and QoS Routing in 6LoWPAN Mesh Networks
White Paper A routing protocol is needed for the mesh topology approach, which must take into account the very limited features of the network This paper proposes an energy aware QoS routing protocol for 6LoWPAN based on extension of 6LoWPAN Ad Hoc Routing... [18 Jul 2008]
Bidirectional Optical Ring Network Having Enhanced Load Balancing and Protection
White Paper The network architecture proposed in this paper is a low-cost flexible solution consisting of two dual buses located over a physical bidirectional ring network topology. The presented distributed resilience algorithm is able to automatically... [10 Jul 2008]
Load Balancing in Arbitrary Network Topologies With Stochastic Adversarial Input
White Paper It assumes a system of n processors connected by an arbitrary network topology. A node can execute one job per step, and can also participate in one load balancing operation in which it can move tasks to a direct neighbor in the network. [10 Jul 2008]
Control of End-to-End Delay Tails in a Multiclass Network: LWDF Discipline Optimality
White Paper Using large deviations techniques, this paper proves that, in a queueing network of arbitrary topology, the LWDF is an optimal discipline to satisfy asymptotic ("tail") constraints on the end-to-end delay distributions. [03 Jul 2008]
Multihop Scatternet Formation for Bluetooth Networks
White Paper The protocol is executed at each node with no prior knowledge of the network topology thus being fully distributed. The selection of the Bluetooth masters is driven by the suitability of a node to be the "best fit" for serving a master. [03 Jul 2008]
Improving Topology Data Base Accuracy with LSP Feedback
White Paper Since the bandwidth available changes as new LSPs are established and terminated the topology database will develop inconsistencies with respect to the real network. In constraint based routing a topology database is maintained on all... [03 Jul 2008]
INSIGNIA: An IP-Based Quality of Service Framework for Mobile ad Hoc Networks
White Paper The framework is based on an in-band signaling and soft-state resource management approach that is well suited to supporting mobility and end-to-end quality of service in highly dynamic environments where the network topology, node connectivity... [03 Jul 2008]
QoS-Based Virtual Private Network Design for an MPLS Network
White Paper Here, the VPN design is modeled as a mixed Integer Programming (InP) optimization problem to minimize the cost of laying out a VPN supporting different traffic types and service classes on a given topology while meeting QoS requirements. [30 Jun 2008]
Email Worm Modeling and Defense
White Paper Email worm propagation is compared on three topologies: power law, small world and random graph topologies; and then study how the topology affects immunization defense on email worms. The observations suggest that the node degrees of an email... [19 Feb 2008]
Optimal Design of Reliable Network Systems in Presence of Uncertainty
More specifically, the reliability of a network system can be improved through redundancy allocation, or for a fixed network topology, by selection of highly reliable links between node pairs, yet with limited overall budgets, and other... [09 Jan 2008]
