The method for calculating far field of the antenna system for a given radiation pattern requirements is developed. Antenna system is two coaxial dipoles of vertical polarization range 94–100 MHz. This method involves the influence of tower elements. The rigorous mathematical model of the antenna system, based on the Pocklington integral equations is proposed. Electromagnetic field scattering by elements of the tower is defined by a set of the integral equations of the I kind. The efficient numerical methods for developed mathematical model are used to optimize the location of the antenna system for a given configuration section of the tower.

Network virtualization (NV) allows an effective use of heterogeneous physical networks through division into application-specific virtual networks. Such virtual networks become independent from the physical infrastructure on the application level, thus decoupling applications from the physical networks. In order to maximize the revenues infrastructure providers have to allocate network resources to the virtual networks in an efficient way. This paper investigates time-varying resource allocation that means virtual network embedding for virtual networks of different purpose with time-varying virtual networks demands.
Key words: network virtualization, dynamic VNE, intelligent transportation systems, infrastructure provider, service provider.
