MAC protocol for wsn.
Critical design.
Two schedules for energy conservation
Scheduled access and Unscheduled access.
LPL MAC with scheduled wake up after transmissions.
Retransmission procedure in unscheduled access.
Retransmission procedure in scheduled access.
Introduction to network simulators.
It should perform simulations of our algorithms.
It should have models for wireless transmissions and battery models.
It should be extremely scalable.
It should be efficient for large simulations.
There should be technical support.
Comparison of Network simulators.
Why are we using QualNet?
Rapid prototyping of protocols
It can do the comparative performance evaluation of alternative protocols at each layer
It has Built-in measurements on each layer
Got Modular, layered stack design
Has a Standard API for composition of protocols across different layers
It has Scalability through support for parallel execution
Got GUI Tools for system/protocol modeling
