This paper presents Griffin, a scheme of geometric routing on flat names to conduct massive content distribution and retrieval. A tree-based metric space T is proposed according to the concept of hierarchical division of symbol space. In Griffin, the network topology is embedded into the T-space, and content names are mapped to the T-space. Content publication and retrieval are supported by geometric...
Anonymous communication is a challenging task in resource constrained wireless sensor networks (WSN). However, anonymity is important for many sensor networks, in which we want to conceal the location and identify of important nodes (such as source nodes and base stations) from attackers. Existing WSN anonymous protocols either cannot achieve complete anonymity, or have large computation and/or storage...
