Data Transmission via Wireless Channel to Store in a Remote Device Employing Error Detection and Correction Code

Data collection from wireless sensor array or sensor network is essential for diverse applications such as weather monitoring, agriculture data monitoring etc. During wireless data communication, the communication channel may be subjected to channel noise and thus introduce transmission error which occurs receiving of misinformation about the situation. The main objective of this research is to develop a wireless data acquisition system which can collect data from wireless sensor array employing error detection and correction code. The transmission end of the system collects data from various sensors and then transmit them employing linear block code. The receiving unit receives the code word transmitted by transmitter circuit, check error, correct the error bits if any error occurs and finally decode data. The data is then stored in an SD card for further analysis. The system is tested for collecting data from a sensor array consisting of three sensors. The result shows that the system is capable of detecting and correcting an error to ensure error-free communication through a noisy channel.
