In a sensor network, the nodes that have a packet
loss rate greater than a given threshold are called lossy
nodes. Lossy nodes adversely affect network
performance and collectively cause breakdown of
network service in many cases. In this paper, we propose
a new and simple approach to identify the lossy nodes
from passive end-to-end measurements. Specifically, we
consider the case of identifying lossy nodes during the
aggregation of data from a collection of the sensor
nodes to a sink node. The proposed method is based on
the hamming distance of sequences on receipt/loss of
aggregated data between each pair of parent-child node.
With prior knowledge of the reverse data aggregation
topology, our approach can identify all lossy nodes
effectively. Finally, we validate the proposed approach.
