The random forest algorithm is one of important supervised machine learning (ML) algorithms. In the present paper, the accuracy of the results of the random forest (RF) algorithm has been improved by the use of the One Hot Encoding method. The Intrusion Detection System (IDS) can be defined as a system that can predict security vulnerabilities within network traffic and is located out of range on a network infrastructure. It does not affect the efficiency of the built-in network because it analyzes a copy of the built-in traffic flow and reports results to the administrator by giving alerts. However, since IDS is a listening system only, it cannot take automatic action to prevent an attack or security vulnerability detected from infecting the system, it provides information about the source address to start the break-in, the address of the target and the type of suspected attack. The IoTID20 dataset is used to verify the improved algorithm, where this dataset is having three targets, the proposed system is compared with the state-of-art approaches and shows superiority over them.

A design of MIMO antenna with four elements each one consists of two polarized ports is proposed in this research. The design of each elements based on ZORA which is applied to get the advantage of band frequency flexibility. The proposed MIMO antenna is operated as a single and dual band by adjusting a ground structure. The resonance frequency is 3.9 GHz for single band with bandwidth 1 GHz (3.4–4.4) GHz at -10 dB with −27 dB isolation. The resonance frequencies for dual band are 4.95 and 7 GHz with bandwidth 1.23 GHz (4.03–5.26) GHz and 410 MHz (6.88–7.29) GHz at −10 dB and less than −12 dB isolation for both bands. The obtained size of FR-4 PCB for single band is 77 × 150 mm2 while 82 × 150 mm2 for dual band which are suitable for future smartphone.

Black Silicon (BSi) is a semiconductor with a surface modified to get a very low reflectivity and correspondingly high absorption of visible light. P-type <100> silicon wafers were used to prepare very low reflecting samples. These samples may use as substrates in optoelectronic applications. Electrochemical etching at different etching current, and time were applied. B-silicon is chemically equal to normal silicon, differs in surface treatment that changes a morphology. This special morphology is demanded for absorption enhancement which involves maximum light absorption. Surface roughness is done by texturing or trenching a silicon wafer surface. As these structures are in place, and as they are small enough, incident light will be more absorbed and less reflected, this is what gives black silicon its name. BSi was characterized by (FESEM), structural analysis indicates that BS layers were formed. The porosity was in the range of (10–40) % and it is dependent on etching time and etching current value. Etching density is 0.1073/mm2. Reflection analysis shows satisfying minimum reflectivity spectrum with the intensity of peaks decrease and red shifted with increasing the etching current. A peak of the Photoluminescence ranges about 360 nm, PL peaks are blue shifted and proportional to etching current. The band gap energy ranged from 2 to 3.4 eV, it is affected with porous morphology and directly proportional to etching current values
