ONE UNEQUAL ERROR CONTROL METHOD FOR TELEMETRIC DATA TRANSMISSION

Tomáš Hirner – Peter Farkaš – Srečko Krile

   In wireless sensor networks (WSN) it is necessary to use very simple codes for transmission of information since the nodes in these networks have usually only limited energy available not only for transmission but also for processing. On the other hand, common codes do not usually take into account the fact that in case of telemetric information the weights of individual orders are not equal and errors in different orders cause different deviations from correct value. In this contribution, new very simple codes for transmission of telemetric information on WSN will be presented, which take into account the above- mentioned requirements. Resulting square deviation will be used as a quality evaluation criterion.

Keywords: telemetric information, resulting square deviation (RSD), low-density parity-check (LDPC) codes, unequal error control (UEC), wireless sensor networks (WSN)
