Adaptive Bandwidth Management in Heterogeneous, Mobile, Wireless Networks

In this project we address the management of wireless bandwidth in heterogeneous networks typified by the MOSAIC program for military applications and mixed wired, wireless, and satellite networks that are being commonly deployed for a multiplicity ofcommercial applications. The main goal is to strike a balance between efficient use of scarce and unstable bandwidth resources and the QoS guarantees made to real-time users and for low latency/ high priority applications. Specifically, we will developsolutions that will allow such a network to provide:¿ differentiated services to real time and best effort traffic¿ bandwidth allocation and, more generally, performance guarantees to accepted real time connections¿ resource aware and precedence compliant Call Admission Control to enforce guarantees¿ efficient and fair bandwidth sharing among applications in the same class;¿ enforcement of priorities across traffic classes;¿ renegotiation of bandwidth and other resource when path characteristics change after connection setup;In Phase II, we will perform high-fidelity simulations to demonstrate efficacy of these techniques in both MOSAIC and FCS communication scenarios. The software will be developed at a level of fidelity that is capable of being directly transitioned to anoperational platform.
