摘要： A handoff method is provided in a communication network including a plurality of fixed nodes attached to a router connected to at least one external network, and at least one mobile node associated with a current fixed node. The method detects movement of a mobile node; prepares a handoff of the mobile node from a current fixed node to potential fixed nodes upon detecting movement of the mobile node; decides whether to handoff to one of the potential fixed nodes as a target fixed node; and performs the handoff from the current fixed node to the target fixed node. The handoff method enables the mobile station to quickly move its association from one access point to another by minimizing a probe delay which is a primary contributor to handoff delay.

摘要： An apparatus and method for detecting a motion vector by converting an input image into gradient pattern information and comparing gradient pattern information in a motion detection area of a current field with representative pattern information of a previous field. A gradient pattern converter converts a gray level of each pixel in a motion detection area in an input image into a gradient bit pattern by comparing differences between the gray level of the pixel and gray levels of its adjacent pixels with an arbitrary threshold value. A motion vector detector forms a search area sequentially in the motion detection area, compares a gradient bit pattern of the search area with a representative bit pattern of a previous image to calculate and accumulate correlation values, and determines a difference of coordinates of a search area which results in a maximum correlation value and coordinates of the representative bit pattern as a motion vector.
