TANDEM

TANDEM - Ein extrem verbrauchsarmes, skalierbares, tandemprozessorbasiertes Funksystem für sensorische, aktuatorische und kennzeichnende Anwendungen

An extremly power-efficient, scalable, Tandem-processor-based radio system for sensing and actuation application

As part of the BMBF-funded TANDEM project, our research group is looking at integrating so-called diversity techniques into wireless sensor networks. Specifically, we are interested in:

  • Network coding in wireless sensor networks
  • Partial forwarding of only correctly received parts of a packet in order to prevent error propagation
  • Integration of diversity techniques with energy-efficient MAC protocols and investigating its effect on energy consumption. This is desirable because the current MAC protocols for WSN's try to minimize the energy utilization by addressing issues such as efficient scheduling, idle listening and Overhearing. However these protocols do not take advantage of additional collaboration from distant nodes with relatively low SNR values but which can possibly participate in cooperative communication.
