ReSNE: Reconfigurable sensor network emulator virtualizing integrated large-scale sensor network

In this study, we propose a reconfigurable sensor network emulator (ReSNE) that realizes a virtual large-scale sensor network environment by combining pseudo sensor/network devices and real ones. This is necessary as it is difficult to evaluate nationwide sensor networks using a real environment because of the need for a large number of real sensor nodes and related devices such as base stations, in addition to a large dedicated communication network. To emulate sensor network traffic, we also use a sensor data generator that generates sensed data packets in the network based on specific user-defined parameters. Furthermore, we develop an auto-configuration tool to enable us to set up the environment quickly. Here, we discuss details of the proposed ReSNE architecture and present some of the evaluation results obtained.
