Simulative evaluation of a decentralized packet synchronization algorithm for short range mobile radio networks
D. Hubner, Simon A. Hoff · 2003
Hoff et al. (Proc. IEEE Vehic. Techn. Conf., 1991) presented the transmit majority synchronization (TMS) algorithm for decentralized mobile radio networks. A first scenario was analyzed, and early simulation results were given. Detailed simulation results of TMS are presented with a comparison to a simple reference protocol called last received synchronization (LRS). A different performance measure, the synchronization time of two unsynchronized groups, is evaluated for different group sizes and vehicle speeds. TMS shows a good performance in any case. Looking at realistic group sizes and group ranges TMS needs fewer than three frames to synchronize the two groups completely. LRS is a trivial algorithm, which does not need any overhead. Nevertheless, the performance is worse than that of TMS. The synchronization time of LRS is 2 to 6 times larger than with TMS.>
