Abstract

In this paper we propose a new routing paradigm, called pseudo-geometric routing. In pseudo-geometric routing, each node u of a network of computing elements is assigned a pseudo coordinate composed of the graph (hop) distances from u to a set of designated nodes (the anchors) in the network. On theses pseudo coordinates we employ greedy geometric routing. Almost as a side effect, pseudo-geometric routing is not restricted to planar unit disk graph networks anymore, but succeeds on general networks.
