A Survey of Cross-Layer Design for Wireless Visual Sensor Networks

摘要

Wireless Visual Sensor Network is a collective network of nodes capable of collecting, processing, and transmitting a huge amount of image/video data from a region of interest to the base station. These nodes are equipped by cameras and are characterized by their limited resources in terms of computational capability, bandwidth and battery power. This type of Networks are more complicated and challenging compared to traditional wireless sensor networks. Therefore, a number of solutions have been recently proposed such as the cross- layer designs, which is an interesting research topic. It allows sharing information across all network layers even the nonadjacent ones, in order to improve the wireless network functionality and to obtain performance gains. In this article, we will present a survey of cross-layer design in Wireless Visual Sensor Networks where we will classify the recent proposals in this area in term of their architecture, interaction categories and theirs outcomes.
