To what extent could ILNP optimize handover efficiency

In this paper, we focus on handover efficiency of Identifier-Locator Network Protocol (ILNP), which is a lightweight mobility solution. Our goal is to improve the handover performance of ILNP without introducing large changes and additional costs to the protocol. We first give a general algorithm for handover optimization of such host-based mobility protocols. Then we analyze the algorithm to find out to what extent we could optimize ILNP. Evaluation results show that the algorithm is efficient in reducing signaling overhead and handover latency in some cases while infeasible in other cases. Be guided by the evaluation results, we propose design of an ILNP extension called ILNP+. We also make simulations based on real user mobility models to demonstrate the feasibility of our proposal.
