- Abstract
In this paper, we propose an energy-efficient compression scheme for wireless multimedia sensor networks. To do this, we analyze the characteristics of multimedia data under the environment of wireless multimedia sensor networks. First, this paper proposes a multimedia sensor data compression scheme based on the Chinese Remainder Theorem by considering the limited resources and restriction of the sensor networks. The proposed scheme utilizes the Chinese Remainder Theorem that is performed based on the modular operation in a category of basic arithmetic operations for data compression. Moreover, for the maximization of compression efficiency, it uses a pre-processing algorithm that consists of dynamic area extraction and bit-plane deletion before conducting the compression scheme. To show the superiority of our scheme, we compare the existing multimedia data compression scheme with our compression scheme. Our experimental results show that our proposed scheme increases compression ratio while reducing the number of compression operations compared to the existing compression scheme.
