Abstract: Described is a link-state routing protocol used in a mobile ad hoc network or in an Internet for disseminating topology and link-state information throughout the network. Reverse-path forwarding is used to broadcast each update along the minimum-hop-path tree rooted at the source of the update. Each path tree has the source node as a root node, a parent node, and zero or more children nodes. Updates are received from the parent node in the path tree for the source node that originates the update. Each update includes information related to a link in the network. A determination is made whether to forward the update message to children nodes, if any, in the path tree maintained for the source node originating the update in response to information in the received update. This information itself can indicate whether the update is to be forwarded to other nodes.

Abstract: Described is an internetworking system having various mobile ad hoc extensions to the Internet that are particularly suited to the dynamic environment of mobile ad hoc networks. The internetworking system includes any combination of a link-state routing protocol for disseminating topology and link-state information over a multi-hop network comprised of nodes, a neighbor discovery protocol that can detect the appearance and disappearance of new neighbor nodes, an address format that facilitates deployment of IPv6 nodes in a predominantly IPv4 network infrastructure, a queuing mechanism that can update information upon resuming interrupted communications between nodes, and dynamic network measurement techniques for adaptively using wireless bandwidth when establishing and maintaining connections between nodes and a server.

Abstract: Described is an IPv6-IPv4 compatibility global aggregatable unicast address format that enables incremental deployment of IPv6 hosts and routers within predominantly IPv4 based networks. A globally aggregatable IPv6 address prefix is associated with an IPv4 node having an IPv4 address and deployed in the network. The IPv4 node is configured with an IPv6-IPv4 compatibility address that includes a prefix portion and an interface identifier portion. The prefix portion contains the IPv6 address prefix associated with the IPv4 node and the interface identifier portion contains the IPv4 address. Packets addressed to the IPv6-IPv4 compatibility address of the IPv4 node are routed across IPv6 infrastructure using the IPv6 prefix portion or tunneled across IPv4 infrastructure using the IPv4 address embedded in the interface identifier portion.
