Effect of Narrowband Channels on the Control |
Abstract |
In mobile sensor networks, sensor measurem … In mobile sensor networks, sensor measurements
as well as control commands are transmitted over
wireless time-varying links. It then becomes considerably
important to address the impact of imperfect communication
on the overall performance. In this paper, we
study the effect of time-varying communication links on
the control performance of a mobile sensor node. In
particular, we investigate the impact of fading. We derive
key performance measure parameters to evaluate the
overall feedback control performance over narrowband
channels. We show that fading can result in considerable
delay and/or poor performance of the mobile sensor
depending on the system requirements. To improve the
performance, we then show how the application layer can
use the channel status information of the physical layer
to adapt control commands accordingly. We show that
sharing information across layers can improve the overall
performance considerably. We verify our analytical
results by simulating a wireless speed control problem. mulating a wireless speed control problem. +
