A SDN-based Testbed for Underwater Sensor Networks
Encouraged by the success in both terrestrial wired and wireless networks,software-defined networking(SDN)is en-visioned as a promising technique to tackle inherent prob-lems in underwater wireless sensor networks(UWSNs),and propel the development of UWSNs further.As the offshore application deployments of UWSNs are both expensive and labor-intensive,it is urgent to develop efficient experimental testbeds or platforms in order to test or evaluate SDN-based algorithms.In this paper,we propose a novel experimental testbed for SDN-based UWSNs,in which the implementation of the control plane is with one-hop out-of-band RF channel,e.g.,LoRa or LoRaWAN,whereas the traditional underwater acoustic channel serves as the data plane.Armed with the global view of the whole testbed,the two-channel SDN-based architecture not only improves the testbed efficiency,but also increases the testbed flexibility and adaptability.We provide a use case to illustrate how to use the testbed by comparing three different routing control models,such as SDN-based centralized control,SDN-based semi-centralized control and distributed control,and hope to inspire more research with this novel test bed.
