Creating a more accurate Sensor Network Model
[attachment=23978]
The Battery Model
Sensors nodes have limited resources and cannot operate for an infinite amount of time. Predicting sensor node failures is important in creating a network model. Some factors that can cause a network failure are battery power, geographical changes that can cause sensor nodes to go out of range, signal strength, and processing problems. The first feature added to predict sensor network failure was a battery model.
Tracking a Sound
One of the features of this model is the ability to track a sound source based on wireless transmissions from sensor nodes hearing the sound. The Wireless Sound Tracker is primarily responsible determining the position of the sound source.
Conclusion and Future Work
Since the model was created to be expandable, addition sensing capabilities can be added by simply creating a new wireless channel for a particular detection task just as a sound channel was created for the sound sensing capability. Although this is just a starting point to a complete sensor network model, this simple sensor network model acts as a stepping stone for more complex models. Future models could include but not limited to the following.
