Network Quality

Up-gradation of wireless communication system is mainly based on some critical attributes like speed, coverage, interoperability, reliability, cost, security etc. This paper looks potential approaches to network quality analysis based on mobility. In this paper, focus is given to determine handover latency, vital property of mobility. This paper presents simulation to investigate handover effects-handover latency in homogeneous and heterogeneous environment using network simulator NCTUns 6.0 and simulator version 2 (NS-2) respectively for different generations of wireless communication. Also simulation is performed to find out the handover latency with respect to mobile node’s speed and then the results are compared with each other for performance analysis. The obtained results show that advanced generations of wireless communication provides low handover latency as well as higher mobility support which leads to better network performance and seamless connectivity.

Simulation Results

     NS-2 is a tool to simulate networks and events that occur per packet sequentially based on time and are widely used in the research field. NS-2 comes with NAM (Network Animator) that produces a visual representation it also supports several simulation protocols. The network can be tested end-to-end. This test includes data transmission, delay, jitter, packet-loss ratio and throughput. The Performance Analysis simulates a virtual network and tests for transport layer protocols at the same time with variable data and analyzes simulation results based on the network simulator NS-2.

The Impact

The performance of the underwater optical wireless communication (UOWC) system is highly affected by seawater´s inherent optical properties and the solar radiation from sunlight, especially for a shallow environment. The multipath effect and degradations in signal-to-noise ratio (SNR) due to absorption, scattering, and ambient noises can significantly limit the viable communication range, which poses key challenges to its large-scale commercial applications. To this end, this paper proposes a unified model for underwater channel characterization and system performance analysis in the presence of solar noises utilizing a photon tracing algorithm. Besides, we developed a generic simulation platform with configurable parameters and self-defined scenarios via MATLAB. Based on this platform, a comprehensive investigation of underwater channel impairments was conducted including temporal and spatial dispersion, illumination distribution pattern, and statistical attenuation with various oceanic types. The impact of ambient noise at different operation depths on the bit error rate (BER) performance of the shallow UOWC system was evaluated under typical specifications. Simulation results revealed that the multipath dispersion is tied closely to the multiple scattering phenomenon. The delay spread and ambient noise effect can be mitigated by considering a narrow field of view (FOV) and it also enables the system to exhibit optimal performance on combining with a wide aperture.
