A new handoff scheme for macro-mobility scenario

With the increase in need for wireless appliances to support mobility, many schemes have been proposed to improve the quality of service (QoS) levels during handoffs. Although these schemes have been proven to be very effective in improving the latency and packet loss during handoffs to a significant level, they are mainly limited to micro-mobility scenario. In the context of macro-mobility, mobile IP (MIP) still continues to be the major protocol, which is not efficient due to high latency and packet loss. In this paper, we propose a new scheme to handle horizontal handoff in the cases of macro-mobility scenarios. We compare the performance of the proposed scheme with the MIPv6 via simulation in network simulator 2 (ns2) and the results show that the proposed scheme provides significant improvement over MIPv6
