Hierarchy-aware skip graph for sensing resource discoveries onn large-scale sensor overlay networks

摘要

The rapid development of sensor networks has made it possible to build a large-scale sensor overlay network by integrating separated sensor networks all over the world. In our previous research, we proposed to realize sensor overlay networks by connecting their gateways with skip graph (SG) overlay, which is distributed and self-organized, and supports retrieving sensing resources using their properties. Although this method has proven to be effective in some scenarios, the lack of proximity awa
