- The technology of Software Defined Radio (SDR) is a possible solution to interwork flexibly between variouswireless transport protocols. Ubiquitous network, like u-health service network, includes sensor devices or nodes whichdo not facilitate all the same transport protocols to access network. As such this may be in such unreachable situationsas poverty of all required AP (Access Point)’s, faults or contention in a path of particular protocol communication,etc. This paper presents research results of modeling and simulation to analyze transport performance of multi-protocolubiquitous network which includes SDR-based interwork nodes and congestion-controlled AP’s. Focusing mainly ondynamics of overall transport performance rather than protocol execution procedures, this paper employs the Zeigler’sDEVS (Discrete Event Systems Specification) methodology and DEVSim++simulation environment to experiment.
