(English Abstract)
This paper analyzes problems of existing Mobile IP and redesigns component functions, and proposes handover method using LRS and BCS for handover performance improvement. When mobile node moves another domain, the proposed BCS recognizes its mobility. So, BCS manages mobile node's binding information and serves micro mobility. When handover occurs among domains, micro mobility enables using LRS, As BCS and LRS have buffering function, they can reduce packet loss by forwarding the buffered datagram. It's designed component is implemented in LINUX environment. And then, handover performance was evaluated by simulation. The results of proposed handover method are better than existing method in both transmission delay time and packet loss.
