Technical Significance
Approach
 Develop and analyze a new architecture and protocols
for wireless internetworking that reduce communication
and processing overhead.
 Develop and analyze new methods to improve the
performance of TCP over dynamic wireless networks.
 Develop and analyze new approaches to supporting endto-end multipoint communication over multihop wireless
networks.
 Explore the interaction between channel access
mechanisms and packet forwarding in the ability of a
wireless network to support point-to-point and multipoint
reliable communication.
Impact
 Current TCP implementations perform poorly over
multihop wireless networks.
 There is little understanding on the ability of multihop
wireless networks to support end-to-end multipoint
communication.
 Signaling among wireless routers is a form of
multipoint communication.
 Prior approaches to extending the IP Internet to the
wireless domain either treat the wireless segment as a
subnet or use IP as the packet forwarding layer inside
the wireless network. Both approaches have their
limitations.
 More efficient signaling methods for networks
with very dynamic topologies.
 Novel solutions for multipoint communication
over highly dynamic environments (e.g., Naval
surface fire support, command posts ashore).
 More efficient TCP implementations that cope
with the characteristics of wireless multihop
networks.
