> As we all know that loop is an open issue in RPL. Experiment shows that loop occurs quite often. We have proposed a loop free local DODAG repair solution. The proposed repair method does not increase rank, and therefore, it does not create any loop. Also, the proposed repair method does not require any modification to RPL and works for both storing mode and non-storing mode of RPL. It provides benefits to RPL.
