The main advantage of a wireless network is user mobility, which calls for efficient routing support at the network layer. An architecture combines Hierarchical Mobile IPv6 and Network Mobility for a network mobile and mobile nodes move in tandem and make a hierarchy in the wireless network to management of micro-mobility and seamless handoff. But the capability of the architecture for intra domain route optimization is impaired. So we propose a functionality in domain nodes to enable intra domain path optimization for ubiquitous network. It is shown that intra domain cost effect is beneficial in every hierarchical domain that span mesh network topology. We address the key function for our proposed scheme and simulate the usefulness of our proposed method using mathematically analyze. We then testify that the proposal has best performance compared with Network Mobility protocol.
