Open issues in Wireless Visual Sensor Networking

The wireless visual sensor networks (WVSN) target a large variety of distributed, wireless, streaming multimedia networking applications´ areas, ranging from home surveillance to military and deep space applications. However, there are a number of open issues that have to be carefully realized before visual sensor webs become widely available. In this paper, we highlight some of the main open issues and challenges, focusing on the networking characteristics. Moreover, we propose a wireless sensor node protocol stack that takes into account the foreseen networking and A/V requirements of the WVSN applications.
