Data handling in Wireless Multimedia Sensor Networks(WMSN)

The wide increase of the sensor base and the miniaturization of electronic gadgets such as CMOS cameras have led to the wide utilization of wireless multimedia sensor networks in last few decades. The nature of multimedia data exhibits different properties in terms of data size, huge storage requirements, bandwidth utilization, computation and processing overhead, and quality of service issues such as latency, jitter in case of real time and interactive applications. These properties will make the data recording, transmission and storage process more complex under the purview of resource constrained nature of wireless multimedia sensor network. By considering these issues, this book discusses various novel approaches devised for optimizing the process of data collection, data transmission and storage, efficient utilization of energy in various chapters. Initially, the book gives an insight into the preliminaries of the wireless sensor network, its scope and design issues. The book mainly discusses about the application of data Deduplication technique in a clustered hierarchical wireless multimedia sensor network and evaluates various performance related issues thoroughly.
