Wireless sensor networks are recently proposed to provide the interface to embed the physical world into the computer systems. Their unique design requirements and constraints ask for new network protocols to support applications different from current distributed systems. In this talk, we will present our work-in-progress on the design of a landmark routing protocol for sensor networks. Based on landmark election, our proposed approach constructs a hierarchical coordinate structure, which is scalable to network size and robust to topology change. It enables better support of both point-2-point routing and distributed hash tables in sensor networks.
