Performance Analysis of String Topology Underwater Acoustic Networks

摘要

The design of network topologies and protocols is critical to improving underwater acoustic network performance. A string topology is one essential component of underwater networks. This work analyzes its performance in an underwater environment. Theoretical results show that the number of nodes, traffic intensity, packet size, and probability of collision affect the end to end network throughput significantly while physical channel capacity fundamentally restricts it. This research gives one a theoretical direction to design future topology and network protocols for underwater acoustic networks. This work is supported by the Office of Naval Research.
