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
1 Introduction
As the technology related to the wireless and mobile network environments is rapidly being developed, it increases the necessity for research about network mobility that could support the mobility of not only a single mobile node but also the movement of a mobile network which consists of several mobile nodes [1]. The most representative work is that of the IETF (Internet Engineering Task Force) NEMO (Network Mobility) working group. The IETF NEMO working group has proposed several Internet drafts [2], [3], [4].
The NEMO basic support protocol defines a methodology for supporting network mobility by using bi-directional tunneling between the home agent and the MR(Mobile Router). It extends binding messages of Mobile IPv6 and the data transmission of a mobile network can be achieved by using the MR...
