在無線隨意網路(Ad Hoc Networks)中，所有工作站(Stations)間的同步是重要的，如電源管理的機制必需達到時脈同步才能有效率的執行。在標準802.11中，其維持同步的機制為同步時間控制函數(Timing Synchronization Function)，但在多重(multiple-hops)跳躍隨意網路中，有擴張性的問題。所以我們針對多重跳躍隨意網路，提出不同的演算法，並比較其時脈同步之系統性能。

In ad hoc networks, it is important that all stations are synchronized, for example, clock synchronization is necessary for power management. In IEEE 802.11 standard, a Timing Synchronization Function (TSF) is specified for the clock synchronization mechanism. But the TSF faces the convergence problem when it is extensively applied on the multiple-hop ad hoc networks. This thesis proposes different clock synchronization algorithms for this issue and compares the system performance by NS2 simulations on multiple-hops ad hoc networks.
