General Research Objectives
The objectives of our overall research are:
1)To design a S-WAHN Network Time-Synchronization Algorithm
      with the following characteristics:
•Accurate enough to allow for a time-slotted MAC
protocol (i.e., msec accuracy)
•Scalable
•Non-hierarchical and autonomous
•Convergent
•Distributed (Fault tolerant)
2) To design a S-WAHN MAC strategy that can guarantee a
    minimum performance (delay and throughput)
•Resilient to topology changes
•Guarantee performance
•Fair
