Enhanced HIP-based micro-mobility and macro-mobility management by proactive signaling scheme

In current HIP (Host Identity Protocol) architecture, the mobility procedure consist of a three-way handshake between the mobile node (MN) and its peers. This procedure lead to a stopping communication between MN and its correspondent´s nodes (CN), which results in packets loss and delay if the procedure takes some time. HIP is not optimized for micro-mobility. In the literature, several solutions have been proposed, but each requires a signaling procedure during handover. In this paper, the proposed scheme does not require any signaling at the micro-mobility and reduces signaling overhead during macro-mobility. Indeed our mobility scheme is looked ahead-based, thus the mobile node is able to know his prospective network prefix before link on associated future point of attachment. Three signaling types have been introduced and mobility information exchange is before Handover. The performance evaluation is based on an analytical model and tests are in a real environment. OpenHIP is implemented for testing performance of the proposed mobility scheme, unlike other schemes are content to do their tests in a simulated environment.
