A DYNAMIC ROUTE OPTIMIZATION TO SUPPORT NETWORK MOBILITY BY USING HMNR SCHEME

The IETF NEMO working group proposed the basic support protocol for the network mobility to support the movement of a mobile network consisting of several mobile nodes. However, this protocol has been found to suffer from the so-called ‘dog-leg problem’, and despite alternative research efforts to solve this problem, there are still limitations in the efficiency for real time data transmission and intra-domain communication. Accordingly, this paper proposes a new route optimization methodology that uses unidirectional tunneling and a tree-based intra-domain routing mechanisms which can significantly reduce delay in both signaling and data transmission.
