scaling challenges and limitations of conventional silicon transistors have led the designers to apply novel nano-technologies. one of the most promising and possible nano-technologies is cnt (carbon nanotube) based transistors. cnfet have emerged as the more practicable and promising alternative device compared to the other nanotechnologies.  this technology has higher efficiency compared to t...

In this paper, we introduce a configurable Internet browser for accessing Internet using networks with low-quality connection. The goal is to build user-configurable Internet browser from existing software. We propose a new model for accessing Internet that allows a user to keep accessing the Internet even in very low speed and/or with temporary disconnection. In this model, we integrate concep...

Coordinated checkpointing protocol is a simple and useful protocol, used for fault tolerance in distributed system on LAN. However, checkpoint overhead of the protocol is bottlenecked by the link speed. Checkpoint overhead of the protocol increases even if only one link in the network is of low-speed. In a metacomputing environment, where distributed application communicates over low speed WAN,...

Key techniques used in the ANx concept are ATM multiplexing, permanent virtual circuits (PVC), and a variety of modem techniques. These “off-the-shelf” techniques are combined with edge routers that provide IP routing, remote authentication, RADIUS and service-provider selection to create a high-speed Internet access solution. Because ANx is based on asynchronous transfer mode (ATM), it can enh...
