Abstract

In recent years, the demand of multimedia data in wireless sensor networks has been significantly increased for the environment monitoring applications that utilize sensor nodes to collect multimedia data such as sound and video. However, the amount of multimedia data is very large. Therefore, if the data transmission schemes in traditional wireless sensor networks are applied in wireless multimedia sensor networks, the network lifetime is significantly reduced due to excessive energy consumption on particular nodes. In this paper, we propose a novel energy-efficient data compression scheme for multimedia data transmission in wireless sensor networks. The proposed scheme compresses and splits the multimedia data using the Chinese Remainder Theorem (CRT) and transmits the bit-pattern packets of the remainder to the base station. As a result, it can reduce the amount of the transmitted multimedia data. To show the superiority of our proposed scheme, we compare it with the existing scheme. Our experimental results show that our proposed scheme reduces about 71 % in the amount of transmitted data and increases about 188 % in the ratio of surviving nodes over the existing scheme on average.KeywordsWireless multimedia sensor networksChinese remainder theoremEnergy efficiency
