Cross-layer design in autonomous networks - why is the influence only one-way?

Joe Sventek, University of Glasgow, Scotland


There is a substantial body of work on cross-layer design in wireless networks. Most of these efforts are with regards to the passing of physical layer information to higher layers. The typical approach is for the network layer to exploit physical layer information when determining routes between nodes. As such, the network layer autonomously modifies the paths that packets take between nodes to account for signal strength, remaining battery power, and many other physical layer metrics. One can say that the physical layer informs the higher layers.

There has been surprisingly little work in which the higher layers, especially the networking layer, inform the operation of the lower layers. There is no reason to believe that cross-layers design is not a two-way street, with each layer affecting/informing the other. This talk will discuss recent work in which knowledge of routes at the network layer can be used to positively affect the operation of the MAC layer in resource-constrained, wireless networks.

Joe Sventek is the Professor of Communication Systems in the Department of Computing Science at the University of Glasgow, Scotland. His research interests include programmable networks, embedded systems, environmental sensor networks, closed-loop network management, and distributed system architectures.

Prior to joining Glasgow, he was a distinguished engineer/research fellow at Lawrence Berkeley Laboratory (1979-1986), Hewlett-Packard (1987-1999), and Agilent Technologies (1999-2002). Professor Sventek was the principal author of the original OMG CORBA specification as well as several of the Common Object Services (e.g. Trading, Events, and Naming). He has been the general chair for TINA99, Middleware 2001, Middleware 2006 and EuroSys 2008, programme chair for COOTS98, TINA99, and Middleware 2000, and a member of programme committees too numerous to mention. He is an advisor to the Wiley Series in Communications Networking and Distributed Systems and a member of the UK Computing Research Committee. He is a fellow of the Royal Society of Edinburgh, the Institution of Engineering and Technology, and the British Computer Society, and is a senior member of the IEEE.
