| Abstract(in English) | This paper considers timing synchronization issues in multi-hop sensor networks with two adjacent cells. Coalescence time in such two cells has been considered recently in [1], where linear estimate of coalescence time is obtained for the IEEE 802.11 ad hoc LAN protocol. Here we introduce probabilistic distribution of coalescence time and rigorous estimate of coalescence time is obtained theoretically under the same condition in [1]. The obtained estimate shows that the linear estimate is valid for moderate number of stations and coalescence time increases nonlinearly beyond a certain station number. From these results, maximum number of station is estimated for which two-cell coalescence time is guaranteed in a practical time limit with certain high probability. |
