A Residual Error Control Scheme in Single-Hop Wireless Sensor Networks
MetadataShow full item record
In this paper a new energy-efficient error control mechanism based on Redundant Residue Number System (RRNS) is proposed for Wireless Sensor Networks (WSNs). In general, WSNs suffer from burst errors due to their inherent nature. An error detection and correction approach has been developed to handle burst errors more efficiently. Residue encoders transform the sensed data to small-sized and independent code-words with redundant information. When an error is detected at the base station, a new module of remainder code-words will be requested from the encoder nodes. This approach creates spatial diversity against fading in a wireless channel. Overall, the proposed scheme results in saving transmission energy, adding negligible encoder energy consumption.
