performance of the fiber optic networks with different physical topologies such as point-to-point, bus, ring and star, with respect to requirements as bit rates, topology structure, bit. error rate (ber) and optical component characteristics including optical amplifiers, filters, sources and detectors, are analyzed and simulated. for this purpose, maximum number of supportable nodes and throug...

Topology issues have received more and more consideration in Wireless Sensor Networks (WSN). While WSN applications are generally optimized by the given underlying network topology, another trend is to optimize WSN by means of topology control. A number of approaches have been identified in this area, such as topology directed routing, cooperating schemes, sensor coverage based topology control...

Learning low-dimensional topological representation of a network in dynamic environments is attracting much attention due to the time-evolving nature many real-world networks. The main and common objective Dynamic Network Embedding (DNE) efficiently update node embeddings while preserving topology at each time step. idea most existing DNE methods capture changes or around affected nodes (instea...

On the basis of analysis on the scene files of mobility models in Ad Hoc network, the paper presents a network topology snapshots capturing method to obtain the Ad Hoc network topology architecture at any moment. Through analyzing on the Ad Hoc network topology snapshots, some dynamic characteristic parameters of Ad Hoc network, such as the number of network topology in steady state or unsteady...
