Purpose and goal
This project studies the general area of co-optimized designs in wireless networks, in particular for wireless sensor networks. More precisely, this proposal describes the continuation of the existing NORDITE project ´Cross-Layer Optimization in Short-Range Wireless Sensor Networks (CROPS1).´ In the continuation project (CROPS2) we plan to continue in the direction set out by the existing project, however we now focus our efforts on a more specific target application, that of radio spectrum sensing. The target application is motivated by the facilitation of future spectrum sharing techniques based on cognitive radio technology.
Results and expected effects
CROPS1 was mainly concerned with generic technologies for sensor networks. In CROPS2 the target application of radio spectrum sensing has been chosen as a focal point. The new target application was chosen for three reasons: As a result of our work in CROPS1, we initiated an application to the EU ICT-Fp7 on using sensor networks for spectrum sensing to support cognitive radio. That project (SENDORA) has now been granted. CROPS2 is an excellent complement to the EU project, there are many synergies and both projects will leverage on the existence of the other; The CROPS1 steering committee supports it; There are many interesting open problems: we are among the first to suggest this application of wireless sensor networking. Our results will be dissiminated via scientific publication and via the steering committee. We expect that the project will contribute significantly to the fascilitation of future spectrum sharing technology.
Approach and implementation
The project is organized in the following work-packages: WP1 target application; WP2 sensor networking; WP3 sensor data processing; WP4 cooperative transmission; WP5 sensing and radio hardware. A steering committee is monitoring the progress of the work.
