Efficient Communication and System Model for Delay Minimization in UAV-Assisted IoT Networks

An ECSMDM is an efficient Unmanned Aerial Vehicle (UAV) communication and system model that utilizes UAPs as mobile relays to facilitate data transfer across IoT networks. By optimizing the ECSMDM protocol, factors such as packet size and throughput optimization are considered alongside energy efficiency (energy savings) and routing overhead. The purpose of UAVs is to provide a weak direct link between nodes. The Age of Information (AoI) metric ensures information is current. The UAV-BS adjusts its position to improve A2G channel connectivity, considering LOS, NLOS factors, and UAV energy usage. ECSMDM surpasses existing protocols like DSVO, OFDC, and IBUR in all aspects of measurement. The ECSMDM protocol achieves the highest packet delivery ratio of 91.07%, indicating superior network reliability, and the highest network throughput of 567.94 Kbps, reflecting better data transmission. It also records the lowest average latency of 116.36ms, which highlights its responsiveness, and the highest energy efficiency of 405.36 joules, indicating significant saving features. ECSMDM has the lowest routing of 312.54 packets, showing reduced network congestion and better performance. The ECSMDM protocol's performance enhancement in UAV-assisted data transmission highlights its potential to enhance network reliability, efficiency, and effectiveness in IoT networks.
