Cross-layer design methodology

One of the scientific results of the project has been the design of a new architecture for mobile multi-hop ad hoc networks. The developed architecture is based on the introduction of the cross-layer principle in mobile-ad-hoc-network organization still maintaining a layered organization of the network architecture and the compliance with TCP/IP protocol stack. More precisely, the MobileMAN cross-layer architecture is based on a layered organization, which can be enhanced with cross layering interactions if information gathered at different layers of the network stack is shared in a common local memory structure (Network Status, referred to as NeSt). Specifically,

- The NeSt, which is the key of the cross-layer architecture, has been completely defined by specifying the NeSt interaction models, and its exported interfaces.

- We designed the software architecture of a NeSt prototype supporting cross-layer interactions between a proactive routing protocol and the middleware platform, CrossROAD, which has been developed during the project.

- Starting from the software architecture, we implemented a proof-of-concept prototype of our cross-layer architecture.

- An experimental phase provided a proof of the benefits of this new approach in MANET design.

- A special attention was devoted to study the performance of our cross-layer architecture. To this end we extended the Network Simulator NS-2with a cross-layer interface (XL-interface) that standardizes vertical interactions among protocols according to the MobileMAN cross-layer architecture.
