The recent advances in wireless communications have raised concerns on next-generation Internet architecture. Wireless sensor networks, mobile ad hoc networks, and 3G/4G cellular networks have received tremendous attention from both industry and academia. They differ themselves from the conventional networks in such characteristics like traffic variability, dynamic topologies, heterogeneity in access technologies, constraints like radio resource, energy consumption. Together with QoS in real-time interactive mobile multimedia applications, they are putting traditional design methodology on network architecture under examination. A common understanding is layering is the source of most performance related problems, and shared information among the protocols layers is critical for performance optimization in wireless networks and the Mobile Internet. With the world-wide push of the wireless communications towards an All-IP infrastructure, an appropriate architecture denotes an essential need.

In this project, a novel Performance-oriented Reference Model (POEM) for future mobile and wireless network will be proposed. Different from a bottom-up approach in classical architecture, the focus here is a much more administrative, declarative approach being top-down. The core idea lies in to realize network autonomy through autonomic management, to instrument this via policy-based management, and to actualize PBM via autonomic control. The whole process highlights facilitated interactions between management and control for which policy-based management plays a key role, and holistic cross-layer design that is part of the control plane. The logical associations are: the autonomic management serves as the interface between the business domain and policy-based management, and is the governor of the whole architecture. The PBM is the instrument of autonomic management, and it fills in the gap between autonomic management and autonomic control. The autonomic management, aligned with part of the constructs form the PBM, is where the self-governing features are realized. The autonomic control, being the actuator of the policies, coordinates the local behaviors of network elements towards the global property. As can be understood, the ultimate goal is to reduce the human network performance tuning efforts as much as possible, or even eliminate the necessity of manual network management.
We use OPNET Modeler and its specialized ACE, Distributed Agent Controller, Wireless and UMTS models to build the POEM-enabled mobile networks. OPNET will be especially helpful for us to easily introduce new components into the existing models, to simplify getting access to the low-layer information, and to effectively conduct experiments and analyze results. The node editor, process editor and the Interface Control Information (ICS) editor will be the primary tools to model the POEM management and control plane. Statistic probes will be distributed and extensive simulations will be carried out to investigate the degree of network autonomy can be achieved by POEM.
