Cross-layer (MAC and transport) optimal rate assignment in CDMA-based wireless broadband networks

Increased demand for wireless broadband data services has led to a reexamination of system design, particularly with respect to optimal resource allocation. This paper considers a wideband CDMA network with arbitrary but known layout and variable rate assignments, which is connected to a traditional wired network. We show that, by using an optimization framework, it is possible to construct a distributed rate assignment algorithm which addresses both MAC and transport layer issues (i.e., interference and congestion control) simultaneously.
