Due to the fragility of small sensors, their finite energy supply and the loss of packets in the wireless channel, reports from sensors may not reach the sink node. In this paper we consider the problem of sensor data collection in the presence of faults in sensor networks. We develop a data collection protocol, which provides expected reliability guarantees while minimizing resource consumption by adaptively adjusting the number of retransmissions based on current network fault conditions.
