Image compression techniques in Wireless Multimedia Sensor Networks

Abstract

Wireless Multimedia Sensor Networks (WMSNs) provide realization of applications which is usable everywhere and address to many fields like mobile health care, environmental surveillance and traffic monitoring. Amount of data causes to traffic in memory resources, difficulties in operation, and excessive power consumption - which is the most important one- for every node while WMSNs transfer multimedia data during those applications. That kind of problems is vital for WMSNs which already have limited resources. Image compression can be one of the effective solutions to overcome those problems. Thus, network lifetime of WMSNs can be increased significantly and the bandwidth can be used in a more effective manner. The main purpose of this study is to investigate image compression algorithms used for WMSNs in the literature in terms of their advantages and disadvantages after giving brief information about WMSNs.
