The growing number of mobile devices challenges existing radio-frequency networks. Therefore, the LiFi/RF hybrid network (HLRN) was proposed to mitigate the increased load of the radio-frequency data rate, providing greater system throughput than that of independent LiFi or RF networks. In hybrid networks, the main problem lies in load balancing which reduces network performance. Therefore, MT studied load balancing techniques in the hybrid network, focusing on the part of assigning the access point to users. In it, user allocation of the domain is a challenge since it is limited to the productivity expected by each user. Five techniques were used divided into three phases, namely: received signal strength (RSS), particle swarm optimization (PSO) and deep learning methods (FFNN, CNN and CBPNN). An event such as the availability of high noise for power or the effect of basic user volatility (mobility) on productivity was studied, which was carried out in three stages. The results showed that the highest productivity and load balance was obtained using the technique of improving the swarm of particles while the satisfaction of the user was obtained the highest percentage using deep learning methods (CNN). The discussion was attended by the assistant head of the department for scientific affairs and graduate studies (Prof. Dr. Mohammed Yousef Hassan). On this occasion, we congratulate the student Iman Khaled Ibrahim and wish her continued success.

The Internet of Things (IoT) has tremendous advantages in many applications such as industrial environments, smart homes, smart cities, smart environments, agriculture, control of critical infrastructure and smart health. However, as the number of IoT devices increases and more information is shared between IoT devices, providing security becomes a primary concern for researchers and developers. IoT devices have low power, and limited computing and storage capabilities and most of their connections are wireless, making them vulnerable to multiple attacks. The objective of this thesis is to propose a safe environment for the operation of the Industrial Internet of Things (IIoT). The research methodology consisted of three phases. Phase one includes implementation of two-factor authentication (TFA) via token (APIKey), between industrial IoT devices, using the TOTP algorithm and ESP8266 microcontroller. The second stage is to build a security portal (Raspberry pi) to detect and prevent intrusions on IoT devices. The third stage is the use of monitoring and logging tools based on the SIEM system, which consists of a group of open source systems such as (wazuh, Elasticsearch, Logstash, and Kibana) to collect and analyze log data, display it on the Dashboard and issue real-time alerts. The proposed system could prevent and detect (Brute-force, Dictionary DDoS / DoS, MITM) attacks and rootkits and hidden processes. The discussion was attended by the Assistant Head of the Department for Scientific Affairs and Graduate Studies (Prof. Dr. Mohamed Youssef Hassan). On this occasion, we congratulate the student (Marwan Alaa Hussein) for obtaining the master's degree, and we wish him continued success. 

A seminar entitled (AUTOMATIC FOOD-INTAKE MONITORING BASED ON IOT EMBEDDED SYSTEM FOR ALZHEIMER’S PATIENTS) was given by Lect. Dr. Amir Qais Obaid from the Control and Systems Engineering Department. The lecture was related to his Ph.D. thesis from Western Michigan University / College of Engineering and Applied Sciences.

In the United States, more than 80% of patients care is provided at home by more than 16 million family members, friends, or other unpaid caregivers. Alzheimer’s patients in the middle and late stages begin to lose the ability to know the significance of drinking and eating even when hungry. It is essential to use technology to enhance these patients’ daily lives while simultaneously reducing the significant time spent by the caregivers. Developing a successful Food-Intake Monitoring System (FIMS) to monitor and encourage the patients to get their meals will reduce the cost of individual caregiving and ease the situation of loved ones caring for their elders and allow the patients to feed themselves. In this dissertation, FIMS implementations based on three different realizations have been defined and implemented using embedded IOT system Raspberry Pi 3 Plus, and tested at the Digital Signal and Image Processing Laboratory (DISPLAY) at Western Michigan University. The FIMS will monitor the eating activity and send alerts or emails to the caregiver and, at the same time, prompt a video after a period of time when the patient does not eat, encouraging them to eat or reminding them how to eat. The seminar was attended by the Assistant Head of the Department for Scientific Affairs and Graduate Studies (Prof. Dr. Mohamed Youssef Hassan).

The performance of WLAN working at 2.4GHz and 5 GHz is assessed in home-like areas under the widely used applications and the assessment is in terms of throughput and delay. The utilization of a single AP showed degradation in performance, due to congestion because all nodes use the same transmission channel, which was shown clearly in the home use case, which is the case that used a data rate of 6 Mbps, in both (a and g) standards and the effectiveness is about (1.1% and 1.3%), respectively. On the other hand, using two APs improves the performance for the same case, where the effectiveness ratio reaches about (28% and 65%). Since it mitigates the congestion because each AP uses different communication channels in the home case. In the case of the office environment, we found that in the case of data rates of 6 Mbps, the effectiveness ratio of both (a and g) standards is about (0.33 % and 0.25 %), respectively. The discussion was attended by the Assistant Head of the Department for Scientific Affairs and Graduate Studies (Prof. Dr. Mohamed Youssef Hassan). On this occasion, we congratulate the student (Sarah Khalaf Jawad) for obtaining the master's degree and we wish her continued success.

In heterogeneous computing systems, work scheduling effectiveness is crucial for high-performance software execution. The programs are to be considered as multiple sequences of tasks that are presented as directed acyclic graphs (DAG). The problem of the current work is divided into two parts. The first part shows that increasing broadcast and redundancy lead to an increase in time consumption. The second problem is solving complexity problems when tasks are scheduled in a heterogeneous manner in a computing system, where the processors in the network may not be identical and take different time periods to carry out the same task. The goals of this work are to reduce the total cost of network-wide broadcasting to minimize the search space and to solve the complexity problem when tasks are scheduled in a heterogeneous way in the computing system. The objectives of this research include, firstly, the implementation of the MOCAB algorithm to find the shortest path between nodes (the least expensive) and calculate the alternative paths. Second, the HEFT algorithm is used to calculate the actual finish time (AFT), earliest start time (EST), and earliest finish time (EFT). Third, performance is evaluated by throughput and response time. Finally, the results were improved by 37% using the genetic algorithm. The performance of the MOCAB algorithm was evaluated with that of the HEFT algorithm in terms of the delivery ratio of packets delivered from the source node to the target node in the network. The results showed that the MOCAB algorithm outperformed the HEFT algorithm by 8%. On this occasion, we congratulate the student (Thaer Habib Nasser) for obtaining the master's degree, and we wish him continued success.
