2005 International Conference on Information Processing in Sensor Networks (IPSN)
In this paper we characterize the impact of imperfect communication
on the performance of a decentralized mobile sensor network.
We first examine and demonstrate the trade-offs between communication
and sensing objectives, by determining the optimal sensor configurations
when introducing imperfect communication. We further illustrate the
performance degradation caused by non-ideal communication links in
a decentralized mobile sensor network. To address this, we propose a
decentralized motion-planning algorithm that considers communication
effects. The algorithm is a cross-layer design based on the proper interface
of physical and application layers. Simulation results will show the
performance improvement attained by utilizing this algorithm.
