Optimization methods for telecommunications networks physical and logical structures

The article deals with reasons why the planned network resource is not used completely. The main attention is paid to the dynamic routing protocol, which does not consider the current load of local network segments according to the principle of its functioning. In the paper local segments loading considers with existence of a constant flow to reduce the computational complexity of the proposed method. The method is proposed in the work to maximize the use of network resources and resource allocation improving based on alternative routes variation through less loaded local segment.

Technology for building digital elevation models for creating plan of river floor

It is represented method of construction of Digital Elevation Models of river bottom. Measurement were executed double-frequency echo sounder data processing was conducted with the use of DPS “Delta”. Accurasy of DEM corresponds to the scale of topographic plane 1:5000.
