Joint Radio Resource Management for HSDPA and WiMAX Networks

Abstract

A vision of future wireless networks is the coexistence of multiple access network technologies. Different access networks will coexist and the Internet Protocol will be the joint layer. Controlling the resources of these networks is very challenging. This paper deals with two data oriented access networks, the worldwide interoperability for microwave access (WiMAX) and the high speed downlink packet access (HSDPA). A new scheduling algorithm to work with large FTP file downloads is suggested, then a queueing model is analytically developed; this model can be used in developing an efficient joint radio resource management (JRRM) protocol to be used by the joint admission controller that controls the access to the two networks. The developed model can also be used to obtain many important performance measurements such as blocking probability, mean sojourn time and the optimum loads of the two networks.
