Abstract

In nested mobile networks with NEMO basic support protocol [3], the pinball routing problem occurs because since it is based on bi-directional tunneling between the mobile router (MR) and its home agent (HA). In addition, the nodes in the same mobile networks cannot communicate with each other when the network is disconnected from the Internet. In this paper, we propose a route optimization with additional information to solve these problems. For this we employ a new IPv6 routing header, named the destination-information header instead of routing header type 2 to optimize the route in the nested mobile network. The proposed scheme shows at least 32% better performance than ROTIO [4] and similar performance to DBU [5] in inter-NEMO route optimization. With respect to intra-NEMO route optimization, the proposed scheme always has the optimal routing path.
