    Abstract

    The Nuchal Translucency thickness measurement is made to identify the Down
    Syndrome in screening first trimester fetus and presented in this paper. The
    mean shift analysis and canny operators are utilized for segmenting the nuchal
    translucency region and the exact thickness has been estimated using Blob
    analysis. It is observed from the results that the fetus in the 14th week of
    Gestation is expected to have a nuchal translucency thickness of 1.87 plus or
    minus 0.25mm.

    Abstract

    A mobile ad hoc network (MANETs) is a self-organizing system of mobile nodes
    that communicate with each other via wireless links with no fixed
    infrastructure or centralized administration such as base station or access
    points. Nodes in a MANETs operate both as host as well as routers to forward
    packets for each other in a multihop fashion. For many applications in wireless
    networks, multicasting is an important and frequent communication service. By
    multicasting, since a single message can be delivered to multiple receivers
    simultaneously.
