This paper describes a dynamic and adaptive scheme for three-dimensional mesh morphing. Using several control maps, the connectivity of intermediate meshes is dynamically changing and the mesh vertices are adaptively modified. The 2D control maps in parametric space that include curvature map, area deformation map and distance map, are used to schedule the inserting and deleting vertices in eac...

This paper presents a parallel programming environment for mesh generation. Our approach is based on overdecomposition. The programming environment supports: low-latency one-sided communication, global address space in the context of data/object mobility, automatic message forwarding and dynamic load balancing. These are the minimum requirements for developing efficient adaptive parallel mesh g...

Wireless mesh networks are potentially vulnerable to a broad variety of attacks. Hence security is an important consideration for the practical operation of wireless mesh networks. Within security, intrusion detection is the first line of defense in wireless networks as well as wired networks. Unfortunately, wireless mesh networks presents additional challenges due to their decentralized nature...

We describe a dynamic load-balancing strategy for parallel finite element methods with adaptive mesh (h-) and order (p-) refinement. The load-balancing algorithm is based on the tiling load-balancing system, where global balance is achieved by performing local balancing within overlapping neighborhoods of processors. Tiling is applied to each mesh level created by the adaptive h-refinement. Wei...

Infrastructure-based Wireless Mesh Networks are envisioned as a cheap, flexible and appropriate technology to expand the radio coverage of network service providers and to create community networks. In this paper we propose a low overhead architecture which offers Internet connectivity and efficient communications among the nodes inside the mesh. Our solution enhances the performance of the Dyn...
