Code Division Multiple

<p>Since the wireless systems are working under nature environments and influenced by turbulence, weather in Iraq that leads to extended amount of fading signal, dissipation or attenuation. Basic “hybrid Subcarrier Multiplying Spectral Amplitude Coding (SCM-SAC) of Optical Code Division Multiple Access (OCDMA)" indoor or outdoor optical system depends on generally “Multi-Diagonal (MD)" security code by using optical space known as “Free Space Optic (FSO)" that was proposed in this work. It is found that the mention hybrid wireless systems can be used in operating mesh networks. The main proposed idea of hybrid optical technique was analyzed and simulated by normally taking into simulation account that the directly effecting by rain and haze attenuations. In addition, there are mention and description for atmospheric effects, FSO mesh network, modulation scheme, simulation, and the data security. From simulation results, the hybrid system using MD code produces reduced “bit-error rate (BER)" at heavy storm rain to distance or range of 500 m and at drizzle rain up to 2500 m range. And also investigates the performance of using the proposed system with radio over fiber (RoF) for UWB signals through indoor propagation in building applications of wireless channel.</p>

The article presents a hierarchical diagram of the network farm and a model of the network architecture levels. Protocols for disposal full mesh network topologies are considered. Modern data transfer protocol TRILL is presented. Its advantages are analysed in comparison with other possible protocols that may be used in the full-mesh topology. Empirical calculations of data routing based on a Dijkstra's algorithm and a patent formula of the TRILL protocol are given. Two monitoring systems of downloading data channels are described. The data obtained from 40G interfaces through each monitoring systems is presented, and their behaviour is analysed. The main result is that the discrepancy of experimental data with theoretical predictions to be equal to the weight balancing of the traffic when transmitting the batch information over the equivalent edges of the graph. It is shown that the distribution of the traffic over such routes is of arbitrary and inconsistent with the patent formula character. The conclusion analyses issues of the traffic behaviour under extreme conditions.
