Reliability of data transmission across the visual sensor network is a major consent for image data captured by image sensor. The available error correction capabilities integrated in the wireless sensor network modules, it is not sufficient to protect a huge amount of transmitted data. With errors often occurred on the transmitted data, the base-station would not be able to receive the accurate information from the sensor nodes. Hence retransmission of data from the sensor nodes to the sink are required which increase power consumption and decrease the lifespan of the sensor nodes.
