A Hybrid Network Using HLA Federation with Conservative Data Compensation

Abstract

federation that it comprehensively incorporates with wired and wireless network environments, and IEEE 1516 high level architecture (HLA) to not only support seamless data communication but also facilitate mobile hosts to get the higher interoperabilities. We elaborate the IP-based mobility management agent with forwarding client mechanism and deploy federate agents to achieve a low-complicated but high-practical mobility management for a wide variety of mobile devices. As a conventional wireless LAN is concerned, it inherently suffers from an information suspension and intermittent message loss as long as a phenomenon known as handoff occurs. Accordingly, we devise a conservative data compensation model (DCM), namely backup starting point scheme, to cope with the information suspension problem incurred by the handoff procedure. In particular, the DCM would not aggravate distributed servers’ computing loads and exhaust buffer space during client’s short-term disconnection phase. As a consequence, the simulation results indicate that the proposed architecture of HLA federation supports the efficient mobility management, seamless data communication, and low system resource consumption for wireless and mobile distributed systems .
