Efficient Payload Compression in IP-based Wireless Sensor Network: Algorithmic Analysis and Implementation

Algorithm 4

Algorithm description of compression at sink node level.

Procedure CompressdataSink(compressedDataFromSensors)

   sinkWaitingTimeValue ← amount of time to wait before sending the compressed value to

   the terminal

   collectSensorsCompressedData ← compressedDataFromSensors collect the data

   compressed by sensors nodes

   If startCollectingTime is greater or equal to sinkWaitingTimeValue

      compressedSinkData ← ArithmeticEncoding(collectSensorsCompressedData)

      sendToTerminal(compressedSinkData)

   end If

end Procedure
