WiMAX-WiFi unified network architecture, security, and mobility

In this paper, we focus on how WiMAX can be used in an enterprise environment under the assumption that a WiMAX network can be hosted by enterprise, together with existing WiFi networks. Three research questions naturally arise when we consider an enterprise wireless infrastructure built with WiMAX and WiFi - what an integrated wireless network architecture would look like, if it is possible to derive a unified security model for such an integrated network, and how unified seamless handoff can be realized between WiMAX and WiFi to support roaming of enterprise users. We will discuss these questions in detail based on our investigation in our research and present the results we have come up with so far.
