Enhancing MAC-Layer Security and Performance with Adaptive Backoff Optimization

This paper introduces AMBA, an adaptive backoff algorithm that strengthens security at the Medium Access Control (MAC) layer for IoT and vehicular networks. AMBA effectively counters jamming and denial-of-service (DoS) attacks, delivering impressive results: 15 Mbps throughput, a 60% reduction in latency compared to JRMP, and a 67% improvement in packet loss resilience. The Security Threat Resilience Metric (STRM) shows a 20% boost in resilience in hostile environments. Leveraging real-time traffic analysis and physical layer feedback, AMBA detects and mitigates malicious activity while maintaining optimal network performance. Its lightweight design is perfect for resource-limited environments, offering a scalable, efficient solution for securing next-generation wireless networks.
