Abstract:
With the advent of cheap, consumer-owned, wireless networking 
technology, major changes in the fundamentals of contemporary networking 
are under way, replacing customers and providers with anonymous peers, 
and wires with antennas. As networking becomes increasingly open, 
wireless, and disorganized, many new challenges arise. In my talk, will 
present two of my main contributions to this field: DART, and TrueLink.
DART: Dynamic Address RouTing, was the first routing protocol for ad hoc 
and mesh networks to support a table size logarithmic in the size of the 
network. As a node moves, DART dynamically assigns it a routing address 
that corresponds to its current location in the network. Consequently, 
DART can route packets in a highly hierarchical fashion, with large 
scalability gains. An elegant technique for finding the current routing 
address of a node is also provided.
TrueLink is the first practical and comprehensive countermeasure to the 
powerful "Wormhole" attack in wireless networks. Using a wormhole 
attack, malicious parties are able to cause widespread disruption in a 
network, using few and readily available resources. In contrast with 
previously proposed methods, TrueLink requires no synchronization, no 
overhearing assumptions, and can be implemented on standard IEEE 802.11 
hardware.

Biography
Jakob Eriksson is a Ph.D. Candidate at the University of California, 
Riverside, working with advisors Michalis Faloutsos and Srikanth 
Krishnamurthy. He received his M.S. degree in Computer Science in 1998 
from the Royal Institute of Technology (KTH), Stockholm, Sweden. His 
main research interests are in open networks, wired and wireless, and 
the design and implementation of protocols, tools and prototypes to 
facilitate their widespread adoption. Before starting his Ph.D. studies, 
Jakob spent the .com boom as a software developer, teacher and 
entrepreneur in Stockholm. He is also a serial intern, having recently 
visited NEC Laboratories, Microsoft Research, and Intel Research - Berkeley.
