A demonstration of a relaying selection scheme for maximizing a diamond network's throughput

Abstract

We demonstrate a queue-aware algorithm studied in a diamond network topology. This algorithm's decisions are obtained from an analytical optimization framework relying on our technical work [4] and we devise an implementation part by modifying the features of ath9k driver [3] and click modular router [5]. Performance evaluation is conducted through experimentation on the NITOS Wireless Testbed and it reveals a significant rise in total throughput considering a particular networking scenario while also it maintains stability of backlog queues when schedules indicated by Lyapunov-based technique as throughput optimal are selected.
