Sensor Network Management

• Real world deployments need administration tool
• Three key issues monitor must address
• Data overload Data received at server increases
  dramatically with high data rates and number of
  sensors
• Health monitoring Given harsh environmental
  conditions and constraints (i.e. power),
  accurately monitoring motes is difficult.
• Information visualization Many challenges in
  presentation are large amounts of data

Performance

• Efficient querying of large dataset
• What is last reading from a node?
• What are all the readings from a subset of nodes?
  
• What are the node readings in a given time range?

Health Monitoring

• Color scheme used to determine staleness of
  readings from particular nodes in the network
• Current Time Last Reading time staleness
• The larger the interval, the more stale the
  reading
• Success rate of packet delivered to base station
• Throughput of packets sent to base station
• Average link quality based on sensor
  readings/communication between neighbors
• Bandwidth of successful packets received over
  1 second interval

Future Work

• Battery life characterization
• Profile node in various states and length of time
  in each state. Correlate with actual
  measurements.
• Heterogeneous deployments
• Determine best way to monitor deployments with
  different sensor nodes running different
  applications
