White Paper The perception of future Wireless Mesh Network (WMN) deployment and usage is rapidly evolving. In particular, in a large WMN, the dynamic assignment of users to Internet gateways will become a complex traffic engineering problem that will need to... [18 Jul 2008]
Improving Restoration Success in Mesh Optical Networks
White Paper In shared mesh restoration, a distributed signaling protocol is used to reroute connections from failed service paths to restoration paths upon failure events. However, even when the network contains sufficient capacity, the restoration paths could... [18 Jul 2008]
Differentiated Quality-of-Protection Provisioning in Optical/MPLS Networks
White Paper This paper investigates the problem of dynamic survivable lightpath provisioning against single node/link failures in optical mesh networks employing wavelength-division multiplexing (WDM). This paper present a new approach to provisioning... [11 Jul 2008]
Topological Design of Multiple VPNs Over MPLS Network
White Paper The use of sink-tree (multipoint-to-point) routing paths in a MPLS network makes the VPN design problem different from traditional design approaches where a full-mesh of point-to-point paths often is the choice. [11 Jul 2008]
Optimizing the Internet Gateway Deployment in a Wireless Mesh Network
White Paper In a Wireless Mesh Network (WMN), Mesh Routers (MRs) are interconnected by wireless links and form a wireless backbone to provide ubiquitous high-speed Internet connectivity for mobile clients. This paper addresses the IGW deployment problem which... [11 Jul 2008]
A New Paradigm for Load Balancing in Wireless Mesh Networks
White Paper Obtaining maximum throughput across a network or a mesh through optimal load balancing is known to be an NP-hard problem. This paper presents heuristic algorithms for load balancing and maximum throughput scheduling in Wireless Mesh Networks with... [10 Jul 2008]
Distributed Load Balancing Algorithm for Adaptive Channel Allocation for Cognitive Radios
White Paper There is a substantial amount of work in the field of dynamic frequency assignment for WLANs and mesh networks as well. The problem of channel allocation has been extensively studied in the context of cellular networks. [10 Jul 2008]
Load Balancing Strategies for Parallel SAMR Algorithms
White Paper Only adaptive mesh refinement methods reduce the necessary work sufficiently, allowing the calculation of realistic problems. Unfortunately, assigning tasks in a load-balanced manner is even more difficult than for unstructured mesh refinement... [10 Jul 2008]
Medial-Axes Based Cartograms
White Paper This paper, deals with the continuous cartogram problem which strictly retains the topology of the polygon mesh. We develop an algorithm to solve the problem which uses an iterative relocation of the vertices based on a modified medial axes... [03 Jul 2008]
Parallel Transient Non-Linear Analysis of Reinforced Concrete Plates
White Paper It is shown that very high computational efficiency may be obtained by decomposing the finite element mesh into a number of sub-domains for distributed analysis on multiple processors. Through examples it is demonstrated how this efficiency depends... [03 Jul 2008]
On Survivable Access Network Design: Complexity and Algorithms
White Paper New graph theory problems naturally arise from such features of access network models, different from those targeted towards survivable backbone (mesh) networks. This paper models the important problem of provisioning survivability to an existing... [11 Jan 2008]
Interference-Aware Channel Assignment in Multi-Radio Wireless Mesh Networks
White Paper The capacity problem in wireless mesh networks can be alleviated by equipping the mesh routers with multiple radios tuned to non-overlapping channels. This paper presents an interference-aware channel assignment algorithm and protocol for multi... [03 Sep 2007]
Quality-Aware Routing Metrics for Time-Varying Wireless Mesh Networks
White Paper This paper considers the problem of selecting good paths in a wireless mesh network. It is well-known that picking the path with the smallest number of hops between two nodes often leads to poor performance, because such paths tend to use links... [31 Aug 2007]
A Protocol for Macro Mobility and Multihoming Notification in Wireless Mesh Networks
White Paper The problem in such scenarios is how to make mesh nodes aware of the gateway over which data is sent towards the Internet. Wireless mesh networks are cost-efficient means to provide ubiquitous Internet access. [31 Aug 2007]
Low Latency Multimedia Broadcast in Multi-Rate Wireless Meshes
White Paper This paper considers a novel type of multi-rate mesh networks where a node can dynamically adjust its link layer multicast rates to its neighbours. In particular, the paper considers the problem of realising low latency network-wide broadcast in... [25 Aug 2007]
