Nael Radwan is recognised through the Innovative Research Award for research addressing the performance, reliability, and security of message-oriented communication systems in the Internet of Things (IoT). His listed 2026 publications examine MQTT broker behaviour under high-load conditions and the correct enforcement of authentication and access-control policies. These topics are relevant to dependable connected systems, where communication efficiency must be considered alongside security and operational stability. The research profile and publication details provide the basis for this academic recognition. [1] [2]
Abstract
This research profile focuses on experimental investigations into MQTT, a lightweight messaging protocol widely associated with IoT communication. The two supplied 2026 journal articles address complementary challenges: the effect of wildcard subscriptions on broker performance, stability, and security, and the correctness of authentication enforcement and the consequences of access-control list (ACL) misconfiguration. Together, these topics concern how messaging infrastructure behaves under demanding workloads and whether security policies are applied as intended. The publications appeared in Electronics and Applied Sciences, respectively. [1] [2]
Keywords

Introduction
IoT environments depend on communication services that can distribute messages reliably while controlling access to sensitive information. MQTT supports publish–subscribe communication, but practical deployments require careful configuration and evaluation. Subscription patterns can influence message distribution and broker workload, while authentication and ACL rules determine which clients can connect and access particular topics. Experimental research into these mechanisms can help identify implementation weaknesses and inform more dependable deployment practices. [1] [2]
Research Profile
Radwan’s documented research interests, as represented by the supplied publications, encompass experimental evaluation of IoT messaging infrastructure, security enforcement, and broker behaviour under authenticated, high-load conditions. This work connects software performance assessment with practical cybersecurity concerns. Rather than treating efficiency and security as isolated objectives, the publication topics place them within the same operational environment, where configuration decisions may affect service behaviour and access restrictions. The supplied bibliographic information establishes the publication focus but does not independently verify every experimental result or establish additional institutional roles.
Research Contributions
The two studies address distinct but related evaluation priorities:
- Performance and stability: Examining wildcard subscriptions under authenticated high-load IoT conditions provides a framework for investigating broker behaviour when message distribution demands increase. [1]
- Security enforcement: Evaluating authentication correctness and ACL misconfiguration addresses whether access restrictions operate consistently with intended policies. [2]
- Practical relevance: These research directions can inform testing, configuration reviews, and risk assessment for systems relying on MQTT-based communication.

Research Impact
The supplied researcher metrics list 10 documents, 24 citations, and an h-index of 3. These figures offer a quantitative snapshot of the research record as provided; citation totals and author metrics can vary between databases and over time. The two 2026 publications address issues with practical relevance to IoT reliability and security. Their potential value lies in supporting evidence-based testing and safer configuration, although broader impact should be assessed using independently verified findings, subsequent citations, and adoption in operational settings.
Award Suitability
The research themes align with the Innovative Research Award’s emphasis on systematic investigation of technical problems. The publications focus on measurable system behaviour and security-policy enforcement rather than relying solely on conceptual discussion. Their complementary scope supports consideration of performance, stability, and access control as connected requirements for IoT infrastructure. This assessment is based on the supplied publication records and researcher metrics; it should not be interpreted as an independent audit of experimental methodology or a formal adjudication of award results.
Conclusion
Nael Radwan’s listed publications present a focused research direction in MQTT performance evaluation and deployment security. By addressing wildcard subscriptions, authentication enforcement, and ACL configuration, the work engages with practical challenges in dependable IoT communication. The publication record and supplied metrics provide a basis for academic recognition, subject to verification against the original articles and authoritative researcher profiles.
