摘要：Localization is an essential issue in mobile networks because many applications require the mobile to know their locat ions with a high degree of precision. Various localizat ion met hods based on mobile anchor nodes have been proposed f or assisting the mobile nodes to determine t heir locations. However, none of these methods attempt to optimize the trajectory of the mobile anchor node. Different static path planning algorithms are SCAN, DOUBLE SCAN, HILBERT, CIRCUL, S-CURVE. In SCAN, the mobile anchor node travels along a single dimension while in DOUBLE SCAN, the collinearity problem is resolved by driving the anchor in both the x- and the y-directions. In HILBERT, the mobile anchor node is driven along a curved trajectory such that t he sensor nodes can construct non-collinear beacon points and the total path length is reduced, In CIRCLES, the mobile anchor follows a sequence of concentric circular trajectories centered at the center point of the deployment area, while in S-CURVES, the anchor follows an S-shaped curve rather than a simple straight line as in the SCAN met hod. Accordingly, discussed path planning scheme, ensures that the trajectory of t he mobile anchor node minimizes the localization error and guarantees that all of the mobile node can determine their locations
