A Novel Data Collection Scheme for WSNs

In this paper, we present a novel data collection scheme for wireless sensor networks by using separate network coding (SNC). By separately encoding a certain number of data segments in a combined data segment and doing decoding-free data replacement, SNC not only provides efficient storage method for continuous data, but also maintains a high success ratio of data collection. The performance evaluation has been conducted through comprehensive computer simulation. It is shown that SNC outperforms the exiting scheme significantly.
