multicast routing is one of the most important services in multi radio multi channel (mrmc) wireless mesh networks (wmn). multicast routing performance in wmns could be improved by choosing the best routes and the routes that have minimum interference to reach multicast receivers. in this paper we want to address the multicast routing problem for a given channel assignment in wmns. the channels...

many appealing multicast services such as on-demand tv, teleconference, online games and etc. can benefit from high available bandwidth in multi-radio multi-channel wireless mesh networks. when multiple simultaneous transmissions use a similar channel to transmit data packets, network performance degrades to a large extant. designing a good multicast tree to route data packets could enhance the...

The M2 channel protein on the influenza A virus membrane has become the main target of the anti-flu drugs amantadine and rimantadine. The structure of the M2 channel proteins of the H3N2 (PDB code 2RLF) and 2009-H1N1 (Genbank accession number GQ385383) viruses may help researchers to solve the drug-resistant problem of these two adamantane-based drugs and develop more powerful new drugs against...

A large number of molecules are usually required to model atomic walls in molecular dynamics simulations. A virtual-wall model is proposed in this study to describe fluid-wall molecular interactions, for reducing the computational time. The infinite repetition of unit cell structures within the atomic wall causes the periodicity of the force acting on a fluid molecule from the wall molecules. T...

We consider the problem of supporting multipoint communication at the media access control (MAC) layer of broadcastand-select WDM networks. We rst show that bandwidth consumption and channel utilization arise as two con icting objectives in the design of scheduling algorithms for multicast tra c in this environment. We then present a new technique for the transmission of multicast packets, base...

Virtual Reality Retailing (VRR) has proved to be an emerging retailing channel with an ongoing economic activity in recent years. There are plenty of virtual worlds where businesses develop, some of which have developed a self-governing economy retaining its own currency. While there has been considerable amount of research as far as store atmosphere is concerned in brick-and-mortar and web ret...

In this paper, performance of wormhole routed 2-D torus network with virtual channels has been evaluated for cache-coherent shared-memory multiprocessors with execution-driven simulation using various applications. The traac in such systems is very diierent from the traac in message-passing environment and is characterized by traac bursts, one-to-many and many-to-one traac, and small xed length...

Most routers in on-chip interconnection networks (OCINs) have multiple virtual channels (VCs) to mitigate the effects of head-of-line blocking. Multiple VCs necessitate VC allocation schemes since packets or flows must compete for channels when there are more flows than virtual channels at a link. Conventional dynamic VC allocation, however, raises two critical issues. First, it still suffers f...

Various types of Networks-on-Chips (NoCs) have been employed light-weight routers compared with those in parallel computers, and a virtual-channel mechanism, which requires additional logic and pipeline stages, is one of the crucial factors for a low cost implementation of an NoC router in the case of simple tile-based architectures. Although a torus network, which exploits wrap-around channels...
