Scalable logical coordinates framework for routing in wireless sensor networks

In this article, we present logical coordinates based routing (LCR), a novel framework for scalable and location-independent routing in wireless sensor networks. LCR assigns each node a logical coordinate vector, and routes packets following these vectors. We demonstrate that LCR (i) guarantees packet delivery with a high probability, (ii) finds good paths, and (iii) exhibits robust performance in the presence of network voids and node failures....
