CROPS: Cross-layer Optimization in Short-Range Wireless

NORDITE Conference, Stockholm, March 22, 2007

Executive summary

CROPS is a NORDITE project with partners from KTH, NTNU and TKK. The main focus of the
project is to investigate new methods to achieve energy-efficiency in short-range wireless sensor
networks. Our main tool in this task is cooperation; among network nodes and across the OSI
protocol layers.

The project is organized into 6 work packages (WP's), spanning topics in wireless transmission,
networking, source and channel coding, application processing and radio transceiver design. In
addition one WP is devoted to fixing the basic design goals and assumptions of the project, and
one WP organizes demonstrator activities.

The researchers at KTH work mainly in wireless transmission, networking and source-channel
coding. KTH also manages a demonstrator activity build using Tmote Invent sensor nodes. The
activities at NTNU are focused toward wireless transmission, in particular problems related to
link adaptation, and source-channel coding. The team at TKK work mainly in the area of radio
transceiver design.

All researchers in the project meet regularly, and exchange and collaboration has been established.
In addition, one PhD student from KTH is presently visiting NTNU to work on problems in
source-channel coding, and one student from NTNU has visited TKK to establish closer
collaboration between the hardware oriented activities at TKK and the signal processing oriented
work on link adaptation at NTNU. Further exchanges of this kind are being planned.

The presentation will introduce the project, its partners and WP structure, and the main research
results obtained so far. Our results have been reported in traditional scientific papers, in project
reports (for example deliverable D1 on the basic design assumptions), as master thesis reports,
and also in the status reports sent to VINNOVA, NFR and TKK.
