Abstract:

Combined timing synchronization function (TSF) and token polling model, a new Ad hoc networks timing synchronization algorithm was proposed. The proposed algorithm can be switched smoothly between TSF and token polling model according to the number of nodes in Ad hoc networks. The problem of scalability in IEEE 802.11 TSF can be effectively resolved by this algorithm. Simulation results show that the proposed algorithm can achieve the predominant performance of timing synchronization in variable scale Ad hoc networks when the threshold is set appropriately.
