A system for video streaming in wireless sensor networks

This dissertation describes the design and the implementation phases which brought to the realization of a Video Streaming System on a Wireless Sensor Network. In the first part, the Wireless Sensor Networks are analyzed to understand the general constraints and limitations that underneath the development environment. Subsequently this anal- ysis is extended to the Multimedia Wireless Sensor Networks. The document reports also a survey on the current data compression techniques. Such methods were studied to find the best data compression algorithm usable in the Video Streaming System. In the implementation section the requirements and the constraints that characterized the work development are presented, together with the design issues encountered and the solutions adopted. Moreover it is reported the simulation aimed to compare the used network protocol with one of the most common alternatives. Finally the performances of the Video Streaming System are tested and analyzed. The presented system allows to send a video through the diverse nodes of a wireless sensor network till reaching the gateway, where the images flow is displayed.
