... applicability of the ad hoc sensor network for local- ization assistance [13]. An example for the latter scenario is assistance for maintenance and deployment of sensor nodes as well as for task and ... sen- sor nodes. Additionally, we consider the use of mobile robots for reconfiguring single sensor nodes and, therefore, larger ad hoc sensor networks reasonable due to severa...
