In this paper we look at the problem of multi-sensor data fusion when
data is being communicated over channels that drop packets randomly. We
are motivated by the use of wireless links for communication among
nodes in upcoming sensor networks. We wish to identify the information
that should be communicated by each node to others given that some of
the information it had transmitted earlier might have been lost. We
solve the problem exactly for the case of two sensors and study the
performance of the algorithm when more sensors are present. For the
two-sensor case, the performance of our algorithm is optimal in the
sense that if a packet is received from the other sensor, it is
equivalent to receiving all previous measurements, irrespective of the
packet drop pattern.
