Abstract
A comparison between global and local time synchronization when applying beacon mechanism of IEEE 802.11 Time Synchronization Function (TSF) to MANETs (Multi-hop ad hoc network) is presented. The evaluation has been carried out with reference to convergence of time while providing robustness towards mobility and stochastic time-delay. The focus is to demonstrate that in most MANET implementations, global time synchronization strategies are physically more pertinent and attain faster convergence than local time synchronization strategies - the more traditional time synchronization strategies for MANETs.
