Channel-Aware Tracking in Multi-Hop Wireless Sensor Networks with Quantized Measurements

摘要

A channel-aware target tracking approach is proposed for multi-hop sensor networks based on $M$-bit quantized measurements. For two cases where the fusion center has the knowledge of the instantaneous fading channel gains and where only the knowledge of fading channel statistics is available, particle filtering (PF)-based channel-aware tracking algorithms are developed. Furthermore, the posterior Cramer-Rao lower bounds (PCRLBs) for the tracking filters are derived. The improved tracking accuracy and robustness of the proposed approach are demonstrated through simulations.
