Wireless sensor networks (WSN) are an increasingly attractive means to bridge the gap between the physical and virtual world. WSNs are envisioned to be used to fulfill complex monitoring tasks. Space and time play a crucial role in wireless sensor networks, since sensor nodes are used to collaboratively monitor physical phenomena and their space-time properties. A number of techniques and distributed algorithms for location estimation and time synchronization have been developed specifically for sensor networks. Time synchronization is a crucial component of WSNs. Time synchronization schemes developed for traditional networks are ill-suited for WSNs and more appropriate approaches should be suggested. There are many similarities in space and time domains. This affects the location estimation and time synchronization, ranging from applications and requirements to basic approaches and concrete algorithmic techniques. The purpose of this paper is to make this close affinity explicit in order to further a better understanding and improving both domains.
