today’s, a common problem in cities is increasing delay and reducing the speed of traffic. on the other wise increasing costs of acquisition in urban area are not allow new routes and highways. also construction of new highway or street such as imam ali highway and sadr highway in tehran lead to develop new applications (such as brt lane ,…) and become quickly saturate and less efficient. there...

The Internet has seen a strong move to support overlay applications, which demand a coherent and integrated control in the underlying heterogeneous networks in a scalable, res ilient, and energy-efficient manner. A tighter integration of network management and overlay service functionality can lead to cross-layer optimization of operations and management, thus, being a promis ing approach to of...

The increase in civil aviation traffic and, general, going through airspace or a military terminal control area, and the operations temporarily reserved areas bring higher requirements for throughput workload of air controllers. For an objective assessment controllers’ workload, it is desirable to set maximum level that can be required such personnel. This also important planning staffing train...

Active networks allow customized processing of data traffic within the network which can be used by applications to improve the quality of their sessions. To simplify the development of active applications in a heterogeneous environment, we propose “active pipes” as a programming abstraction to specify transmission and processing requirements. We describe how an active pipe can be mapped onto n...
