HMNR scheme based dynamic route optimization to support network mobility of mobile network

A lot of recent research has been focused on developing network mobility management to support the movement of a mobile network consisting of several mobile nodes. In the mobile ad-hoc network environment, network itself can be moved to another point. For the network mobility, 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 intradomain communication. Accordingly, this paper proposes a new route optimization methodology that uses unidirectional tunneling and a tree-based intradomain routing mechanisms which can significantly reduce delay in both signaling and data transmission.
