홈페이지논문 초록 (Abstract)
Recent years have seen a significant increase in demand for multimedia data over wireless sensor networks for monitoring applications that utilize sensor nodes to collect multimedia data, including sound an d video. However, the multimedia streams generate a very large amount of data. When data transmission schemes for traditional wireless senso r networks are applied in wireless multimedia sensor networks, the network lifetime significantly decreases due to the excessive en ergy consumption of specific nodes. In this paper, we propose a data compression scheme that implements the Chinese remainder theore m to a wireless multimedia sensor network. The proposed scheme uses th e Chinese Remainder Theorem (CRT) to compress and split multimedi a data, and it then transmits the bit-pattern packets of the remainder to the base station. As a result, the amount of multimedia data that is transmitted is reduced. The superiority of our proposed schem e is demonstrated by comparing its performance to that of an exist ing scheme. The results of our experiment indicate that our propo sed scheme significantly increased the compression ratio and reduced the compression operation in comparison to those of existing comp ression schemes.
