Images compression techniques for wireless sensor network applications

Adaptive compression for images transmission in resource-constrained multi-hop wireless network applications is considered. In this strategy, development of an energy efficient image compression scheme is proposed as a means to overcome the computation and/or energy limitation of individual nodes. It has the additional benefit of extending the "life" of individual node by saving its energy power. Two methods for energy efficient image compression are proposed and investigated with respect to energy consumption and image quality. Simulation results show that the proposed scheme prolongs the system lifetime and minimizes the computation energy by reducing the number of arithmetic operations and memory accesses.
