This paper is a research of cross-layer handoff scheme based on IEEE 802.16e. By combining the handoff message of 802.16e and Fast Mobile IPv6, this scheme can shorten the handoff delay time.
In the following part of this paper, we simply describe how 802.16e works, and we explain the procedure of Mobile IPv6 and Fast Mobile IPv6. Furthermore, by analyzing the packets that 802.16e and Fast Mobile IPv6 brings out while handoff is processing, we explain how to use the cross-layer architecture to combine those messages from two different layers.
In the final software simulation, the proposed cross-layer handoff scheme is compared with “Mobile IPv6 Fast Handoffs over IEEE 802.16e Networks” which is a draft on IETF. The results of the simulation show that this cross-layer handoff scheme is better than the draft on IETF in handoff delay time. |
