What is the main problem that the APID routing protocol aims to solve in multi-UUV underwater mobile swarm networks?
The main problem that the APID routing protocol aims to solve in multi-UUV underwater mobile swarm networks is the challenge of achieving stable and energy-efficient communication under conditions of high mobility, energy constraints, and unstable acoustic links. Specifically, existing routing protocols suffer from excessive topology maintenance overhead, poor tracking of moving destination nodes, overly simplistic forwarder selection criteria, and inefficient handling of routing voids. APID addresses these issues through adaptive beaconing, self-decision location information diffusion, confidence and angle-based forwarding, and packet buffering, thereby improving packet delivery rate and reducing energy consumption in dynamic underwater environments.
