# Committee Members Designation Position
1 Prof. Adnan Yahya Ahmed Al-Mutawakkil Internal Examiner Chair
2 Prof. Sharaf Abdulhaq Mahyoub Al-Hamadi Main Supervisor Member
3 Assoc. Prof. Ibrahim Abdullah Ahmed Al-Sermi External Examiner Member
The dissertation aimed to enhance Quality-of-Service (QoS) requirements for multimedia applications in wireless networks by designing an intelligent system that integrates cross-layer techniques with fuzzy logic.
The study yielded several key findings summarized as follows:
The proposed approach enabled intelligent and flexible control of wireless network resources to support time-sensitive applications.
The developed model effectively overcame some limitations of traditional models.
The overall performance efficiency of the network was significantly improved.
In light of these findings, the researcher recommended the following:
Adopting intelligent adaptive methodologies in managing resources of wireless sensor networks.
Generalizing the application of artificial intelligence principles to improve wireless network protocols.
Continuing to exploit cross-layer design in next-generation network research.
The dissertation defense was attended by a number of academics, researchers, and specialists, students, colleagues, and the researcher’s family.
