Monitoring the health of a sensor network is important for maintaining the health and normal operation of the network. For large-scale cost-effective monitoring, using inexpensive motes as sniffers is an attractive choice. In this paper, the authors quantify the capability and fidelity of mote-class sniffers for sensor network monitoring. In particular, the authors experimentally quantify the sustainable workload and the accuracy of delay and loss measurements by these types of sniffers.
