    Safety, security, and rescue robotics is an important application field that can be viewed as a prototypical example of a domain where networked mobile robots are used for the exploration of unstructured environments that are inaccessible to or dangerous for humans. Teleoperation, based on wireless networks, is much more complex than what one might expect at first glance because it goes well beyon... View full abstract»

    Wireless controls offer attractive features including flexibility, self-organization, and dynamic networking, especially in mobile control scenarios. At the same time, wireless controls pose new design challenges because network and control performance affect each other. We focus our study on a wireless, mobile, multihop, robot-control scenario and compare the applicability of standard routing pro... View full abstract»

    We explore synergies among mobile robots and wireless sensor networks in environmental monitoring through a system in which robotic data mules collect measurements gathered by sensing nodes. A proof-of-concept implementation demonstrates that this approach significantly increases the lifetime of the system by conserving energy that the sensing nodes otherwise would use for communication.

    Communication-aware motion control allows mobile networked robots to increase the average communication throughput. We exploit that in a multipath fading channel, robots can measure the SNR and adapt their motion to spend slightly more time at positions where the channel is good. Two new such cross-layer strategies are analyzed and evaluated: periodic stopping, where the stop duration is a functio... View full abstract»

    Self-directed movement of radio devices can enable large amounts of power gain since the sources of fluctuations in received signal power due to multipath-induced small-scale fading have highly localized effects. We call the gain achieved by finding a better location the mobility gain. Experimental data for indoor as well as outdoor measurement studies are used to illustrate the potential of this ...

    'Cognitive radio' has emerged as a new design paradigm for next-generation wireless networks that aims to increase utilization of the scarce radio spectrum (both licensed and unlicensed). Learning and adaptation are two significant features of a cognitive radio transceiver. Intelligent algorithms are used to learn the surrounding environment, and the knowledge thus obtained is utilized by the tran... View full abstract»

    Certificate validation is much more complex in mobile ad hoc networks than in conventional networks because online access to trusted authorities is not always guaranteed. For this reason, we require new solutions to overcome both the lack of infrastructure and the limited capabilities of several user devices. In this article we study the application of different mechanisms for certificate validati... View full abstract»
