Localization and coverage are two important and closely related problems in wireless ad hoc networks. Localization aims to determine the physical locations of devices in a network, while coverage determines if a region of interest is sufficiently monitored by devices. Localization systems require a high degree of coverage for correct functioning, while coverage schemes typically require accurat...

Location information of nodes in an ad hoc sensor network is essential to many tasks such as routing, cooperative sensing, and service delivery. Distributed node self-localization is lightweight and requires little communication overhead, but often suffers from the adverse effects of error propagation. Unlike other localization papers which focus on designing elaborate localization algorithms, ...

It is often the odometry accumulative error without bound after long-range movement that decreases the precision of global localization for wheeled mobile robots. Therefore, an efficient approach to odometry error modeling is proposed regarding gentle drive type mobile robots. The approximate functional expressions, between process input of odometry and non-systematic error as well as systemati...
