Abstract

In this paper, a critical view of the utilization ofcomputational intelligence approach from the text steganalysisperspective is presented. This paper proposes a formalization ofgenetic algorithm method in order to detect hidden message on ananalyzed text. Five metric parameters such as running time, fitnessvalue, average mean probability, variance probability, and standarddeviation probability were used to measure the detection performancebetween statistical methods and genetic algorithm methods.Experiments conducted using both methods showed that geneticalgorithm method performs much better than statistical method,especially in detecting short analyzed texts. Thus, the findings showedthat the genetic algorithm method on analyzed stego text is verypromising. For future work, several significant factors such as datasetenvironment, searching process and types of fitness values throughother intelligent methods of computational intelligence should beinvestigated.

Abstract

5G is speculated to transform the mobilecommunications landscape by increasing data rates, latency,coverage and energy efficiency. Radio-over-fiber (RoF) provides ahigh-capacity, efficient and scalable 5G architecture fortransporting radio signals through optical fibers, exploiting theenormous bandwidth of the optical fiber cables. In this paper, anew radio-over-fiber (RoF) architecture for future 5G networks isproposed using SCM-MDM for converging data streams fromdifferent picocells. Different sets of the Hermite-Gaussian (HG)modes are introduced for the SCM-MDM system in RoF. The effectof different sets of HG modes on the RoF system performance arecompared in terms of the transverse electric fields, eye diagrams,modal analyses and bit-error rates. A total throughput of 19.5 Gb/sis achieved

Abstract

Radio-over-free-space-optics (Ro-FSO) is a strongcontender for providing a ubiquitous platform for seamlessintegration of high capacity radio and optical networks withoutexpensive optical fiber cabling. This work presents mode divisionmultiplexing of LG and HG modes in a 40 GHz Ro-FSOtransmission system to realize 4 x 20Gbps over a free space opticallink under clear weather conditions. The signal-to-noise-ratio,received power and constellations will be analyzed.

Abstract

This paper reports on MDM of a combination ofhelical-phased modes comprising ring modes and HG modes.44Gbps data transmission is achieved by a wavelength divisionmultiplexing (WDM) - MDM system of two center-launchedhelical-phased ring modes and two 3μm radially offset HG modeon wavelengths 1550.12nm and 1551.72nm for a 1500m-longmultimode fiber. The power coupling coefficients, degeneratemode group delays and bit error rates are analyzed for differentHG modes and radial offsets.

Abstract

Vehicular Ad hoc Networks (VANET) play a vital Vehicle to Infrastructure (V2I) correspondence frameworks where vehicle are convey by communicating and conveying data transmitted among each other. Because of both high versatility and high unique network topology, congestion control should be executed distributedly. Optimizing the congestion control in term of delay rate, packet delivery ratio (PDR) and throughput could limit the activity of data packet transmissions. These have not been examined altogether so far – but rather this characteristic will be fundamental for VANET system execution and network system performance. This paper exhibits a novel strategy for congestion control and data transmission through Service Control Channel (SCH) in VANET. The Taguchi strategy has been connected in getting the optimize value of parameter for congstion control in highway environment. This idea lessens the pointless activity of data transmission and decreases the likelihood of congested in traffic in view of execution for measuring the delay rate, packet delivery ratio (PDR) and throughput. The proposed execution performance is estimated with the typical VANET environment in V2I topology in highway driving conditions and the simulation results demonstrate and enhance network execution performance with effective data transmission capacity.
