CONCLUSION
Mobile robots in continuous motion face significant wireless connectivity challenges. Current scan-based handoff algorithms are insufficient for meeting the strenuous connectivity demands for supporting features like telepresence for mobile robots. We have shown how wireless map-based AP handoffs can substantially improve the reliability of wireless connectivity for autonomous robots. In fact, these highly informed AP handoffs eliminate many of the interruptions in connectivity due to motion. While we did not observe significant changes in the wireless map across a few days,
future work is needed to investigate how one can maintain up-to-date wireless maps in dynamic environments. Future work is also needed to apply these same highly informed handoff algorithms to other mobile devices like cell phones that have much less accurate localization.
