#Toy Simulator 2014

Authors: Rodny Perez Emily Dolson Josh Nahum

This projects aims to develop a simulator for wireless sensors.

We will something else later

##Todo

• Implementing features:
  • Sensor dependancy (Done)
  • Time occilation (The mean changes over time) (Done)
  • Days or seasons (comming soon)
  • Sensors that varies in mean and standard deviation
  • Sensor pattern
  • Partition sensors by groups (Done)
  • Multiple sensor type (Done)
  • Temperature drifts globally
• Adding correlations
  • Change temperature over time (moran process)
  • Change station to correlated sensor group (Done)
  • Change mean in station to a periodically changin value such as sine wave.

##Errors and anomalies

• Abrupt changes (added)
• Large deviation (added)
• Unusually low variance (change in result from predicted value)
• Deviation from neighbors (variance in result from neigbors) (added)
• Drift towards a particular value (0 or something else) (change over time in unforeseen ways) (added)
• increasingly mean difference

##Ways of representing anomalies

• Change in mean value among multiple sensors. Either within a group or an entire field
• Adjusting the correlation between sensor modalities
