Abstract

In the last years many mobile solutions have been proposed for traditional wireless networks, such as cellular and IEEE 802.11 networks. Multihop networks are another kind of wireless network which have received much attention recently. However, mobility in these networks is not a simple extension of traditional wireless networks. Thus, new mobile solutions are required for wireless multihop networks. Aiming at this goal, this paper proposes a DHCP adaptation intended for wireless multihop networks. The proposal adds intelligence to the DHCP relay agent in order to speed IP address configuration process to mobile clients during handoff.
