Abstract

With the rapid growth of wireless sensor network technologies and the availability of less expensive hardware such as complementary metal oxide semiconductor cameras and microphones has encourage the development of wireless multimedia sensor network. Some application areas for wireless multimedia sensor network are health care monitoring, traffic monitoring, environment monitoring and wildlife monitoring. The constraints of sensors are limited processing capability, limited storage and energy. Energy consumed by sensor during image transmission is very high due to large size of images. Hence, networks lifetime is decreased rapidly. A numbers of techniques have been proposed to enhance the network lifetime. Image compression techniques are one of them. This paper describes the various image compression techniques, which can be used to aid energy efficient wireless multimedia sensor network. Furthermore, we have compared various image compression techniques, so one can find out suitable compression technique for their application.
