Wireless sensor network plays a significant role in the design of future Smart
Grid, mainly for the purpose of environment monitoring, data acquisition and remote
control. Sensors deployed on the utility poles on the power transmission line are used
to collect environment information and send them to the substations for analysis and
management. However, the transmission is suffered from erasures and errors along
the transmission channels. In this thesis, we consider a line network model proposed
in [1] and [2]. We first analyze several different erasure codes in terms of overhead
and encoding/decoding costs, followed by proposing two different coding schemes for
our line network. To deal with both erasures and errors, we combine the erasure
codes and the traditional error control codes, where an RS code is used as an outer
codes in addition to the erasure codes. Furthermore, an adaptive RS coding scheme
is proposed to improve the overall coding efficiency over all SNR regions. In the end,
we apply network coding with error correction of network errors and erasures and
examine our model from the mathematical perspective. / Graduate
