Extensions for Wireless Technology Emulation to Wire-based Network Testbed

Abstract

Services premised on wireless communication are diversifying, and their reliability of the communication is required. On the other hand, many factors are involved in the parameter change of the wireless section, and it is difficult to clearly determine the cause and effect when the wireless section is actually incorporated into the evaluation environment. By emulating the wireless section and fixing the quality of the wireless section, the behavior of the implementation of a specific wireless service can be efficiently evaluated. We have been developing StarBED, which is a large-scale network testbed built with wired networks, and NETorium, which enables application evaluation by imitating a wireless section on a wired network on a large scale. We are designing and prototyping supporting software that can flexibly introduce new functions as an alternative to the supporting software SpringOS that has been operated on StarBED. This paper describes the design of architecture and implementation of the supporting software when the wireless emulation function is realized as an additional function.
