The technology of Dynamic Spectrum Access (DSA) can utilize unused licensed bands not being used by licensed users to improve the capacity and throughput of multi-hop wireless networks working on the ISM bands. However, DSA also brings us a new challenge: how to network the radios in multi-hop DSA networks to improve network performance, such as throughput and end-to-end delay? To address this issue, we propose a STability-Aware Routing Protocol (STARP) for multi-hop DSA networks. STARP can find the most stable path among multi paths to the destination for upper layer protocol. STARP evaluates path stability by utilizing a novel routing metric, which takes into account spectrum switching frequency, spectrum usage, and path length together. Simulation results of NS-2 show STARP is efficient and robust. In addition, STARP can achieve good improvement of TCP performance and shorten end-to-end packet delay significantly.
