In this paper, we present a novel Cluster-based Separate Networking Coding (CSNC) scheme, as a solution to solve the problem of continuous data collection for WSNs with a mobile BS. By separately encoding a certain number of data segments in a combined data segment and doing decoding-free data replacement, CSNC not only provides efficient storage method for continuous data, but also maintains a high success ratio of data collection. The comprehensive performance evaluation has been conducted through computer simulation. It is shown that CSNC outperforms the existing PNC scheme significantly.
