A new micro-mobility protocol for large mobile and wireless networks

When a mobile node becomes highly mobile, the signalling overhead due to the registration becomes excessive in Mobile IP. To reduce this signalling overhead and provide smooth handoffs, many micromobility protocols have been proposed. But they still stiffer from problems such as scalability and inefficiency in packet exchanges. To solve these problems we introduce a new micro-mobility protocol. In the proposed micro-mobility protocol, a domain is structured into two levels and both network- specific routing and host-specific routing are used to improve scalability. It also offers efficient mechanism for packet exchanges within a domain and clearly states the cooperation with Mobile IP during inter-domain packet handoffs.
