Apart from static deployments, sensor nodes in Wireless Sensor Networks (WSNs) are unaware of their location information. In order to estimate their actual or relative positions with respect to other nodes, they are required to self-localize …
Time synchronization is one of the fundamental build- ing blocks for coordinated and power-efficient operation of the networked robots. Ironically, time synchroniza- tion itself is also an energy consuming process which de- mands communication and …
Synchronization of tiny sensor nodes forming Wireless Sensor Networks (WSNs) is a challenging problem due to frequent topological changes, node failures and power, memory and computation constraints. These difficulties promote a self-organizing …
