5. Target Tracking in WSN
Target Tracking is one of the most critical application of WSN in military surveillance operations. It mainly employs:
Detection of the intrusion
Tracking of target movement within the network

6. Challenges in Target Tracking
How could the sensor detection be modeled and how is the sensing coverage determined?
What are the effects of geographic properties of the field on target detection?
How should the sensors be deployed in the region?
The limitation of sensor nodes such as battery power, sensing radius, communication range, etc.
Tracking accuracy and speed.

7. OMNET++ Network Simulator
OMNeT++ is an object-oriented modular discrete event network simulator. It can be used for:
Traffic modeling protocol modeling.
Modeling queuing networks.
Modeling multiprocessors and other distributed hardware systems.
Validating hardware architectures.
Evaluating performance aspects of complex software systems.

8. Modeling and Simulation of OCO over OMNET++ for Target Tracking
The OCO algorithm is very efficient for Target Tracking in WSN. The three types of environments for OCO simulation are as follows:
Stand by (No intrusion).
Single intrusion.
Multiple intrusions.
