Supporting address autoconfiguration for IPv6 in IEEE 802.16e based network

초록

Introduction of IPv6 protocol in IEEE 802.16e based network without any modification could occur many problems due to IEEE 802.16 standard's point-to-multipoint and connection oriented features and absent of the native multicast support. In this paper, we propose a method for supporting address autoconfiguration and DAD mechanism to the IPv6 nodes in IEEE 802.16e based network. The proposed scheme uses multicast and broadcast service (MBS) and the service's transport connection identifiers (MCIDs) and assigns them to the IPv6 node as soon as the nodes complete the layer 2 handover. Using the proposed scheme, IPv6 nodes in IEEE 802.16e network can exchange the ND messages sent to the multicast address. We analyze the network resource usages for the existing method and the proposed scheme. Through the performance evaluation, we see that the proposed scheme can reduce the whole network resource usage up to maximum 32 percent. © 2008 Springer-Verlag Berlin Heidelberg.
