Abstract: In one embodiment, a mobile router receives a multicast-supported router advertisement message from an attachment mobile router in a mobile ad hoc network, the multicast-supported router advertisement message specifying an attachment prefix and a multicast-capable identifier. The mobile router attaches to the attachment mobile router in response to the multicast-supported router advertisement message and according to a protocol requiring establishment in the mobile ad hoc network of a tree topology having a single multicast clusterhead, and selects a default attachment address within an address space of the attachment prefix. The mobile router receives a multicast request, from an attached node, for receiving a multicast stream, and the mobile router outputs a neighbor advertisement message with multicast extension, to the attachment router, that specifies that access to the multicast stream is requested via the default attachment address.

Abstract: Each mobile router in a mobile ad hoc network is configured for identifying routes to nearby nodes that are within a prescribed distance, based on storage of explicit paths specified within routing headers of packets transmitted from a host node to a destination node. Each mobile router also can selectively compress the routing header, based on the storage of the explicit path, resulting in a loose source route type routing header in the packet output from the mobile router. In addition, a routing header of a received packet can be expanded based on the mobile router inserting the explicit path, enabling mobile hosts in the explicit path to forward the packet according to strict source routing. The storage and compression of explicit paths also can be applied to packets specifying reverse routing headers, minimizing the size of the reverse routing headers.

Abstract: An autonomous wireless mobile network is established between mobile nodes configured as wireless autonomous robotic mobile access points. Each mobile node includes a mobility platform, an executable routing resource, and a standardized interface. The mobility platform is configured for supplying sensor data from attached physical sensors, and responding to motor commands from the standardized interface. The standardized interface is configured for converting each sensor datum into a corresponding sensor object, and converting received movement directives into the respective motor commands. The executable routing resource is configured for maintaining a database of world objects representing attributes within an infosphere established by the wireless mobile network based on the sensor objects and received network objects. The executable routing resource also is configured for generating the received movement directives and executing network decisions based on periodic evaluation of the world database, and exchanging the world objects with other mobile nodes.

Abstract: Methods and apparatus for processing registration requests by a Home Agent supporting Mobile IP are disclosed. A registration request is received from each of a plurality of Mobile Nodes, the registration request specifying a care-of address, which may be allocated by the Foreign Agent. A binding is established between each of the plurality of Mobile Nodes and the associated care-of address, each of the plurality of Mobile Nodes being associated with one another. For instance, the plurality of Mobile Nodes may be statically or dynamically assigned the same Home Address. A tunnel is then created between the Home Agent and the care-of address for each of the plurality of Mobile Nodes, thereby enabling a server request to be distributed by the Home Agent to one of the plurality of Mobile Nodes or to a cluster of Mobile Nodes (e.g., associated with the care-of address) via the associated tunnel. For instance, a server request addressed to the Home Address may be forwarded directly to one of the Mobile Nodes assigned that Home Address. Alternatively, when an address such as the care-of address is associated with multiple Mobile Nodes, the Foreign Agent may perform a second level of dispatching such that the server request is dispatched to one of the Mobile Nodes in the cluster.

Abstract: In one embodiment, a more capable device (MCD) in a computer network may determine one or more a critical destinations (CDs), and may transmit an unsolicited reactive routing route request (RREQ) message to each CD. The MCD may then receive a route reply (RREP) message from the CDs having a route from the MCD to the CD, and may store the route at the MCD. Subsequently, the MCD may transmit a RREP message of its own to one or more less capable devices (LCDs) to provide the route from each respective LCD to the CD via the MCD.

Abstract: A network includes network nodes (12a and 12b) and a gateway (20). Each network node (12a) has a corresponding unique in-site Ipv6 address (16a) for communication with the site (14), each in-site address having a first Ipv6 address prefix that is not advertised outside the site. Network nodes can obtain from within the site a unique extra-site Ipv6 address for mobile or extra-site communications (26a). The extra-site Ipv6 address has a second Ipv6 address prefix, distinct from the first Ipv6 address prefix, advertised by the gateway (20) to the prescribed site (14) and the wide area network (22). The gateway establishes a tunnel (24) to each in-site node (12a) using extra-site and in-site Ipv6 addresses a binding cache entry specifying the addresses.

Abstract: Mobile routers establish a tree-based network topology in an ad hoc mobile network, the tree-based network topology having a single clusterhead and attached mobile routers. Each attached mobile router has a default egress interface configured for sending messages toward the clusterhead, and ingress interfaces configured for receiving messages from attached network nodes that are away from the clusterhead. A neighbor advertisement message received from an ingress interface away from a clusterhead is used by the attached mobile router to identify specified network prefixes that are reachable via the source of the neighbor advertisement message. The attached mobile router outputs on its default upstream interface a second neighbor advertisement message that specifies the network prefix used by the attached mobile router, and the specified network prefixes from the neighbor advertisement message received on the ingress interface. Hence, connectivity is established with minimal routing overhead.

Abstract: A source IPv6 mobile node is configured for forwarding an IPv6 packet via an IPv4 connection with a destination IPv6 router. The IPv4 packet includes IPv4 source and destination addresses, a UDP source port and UDP destination port, and a synthetic tag address in the IPv6 destination address field. The synthetic tag address, a valid (routable) IPv6 care of address, has an address prefix routed to the IPv6 router. The address prefix specifies a forwarding protocol, the IPv4 destination address for the IPv6 router, and a site-level aggregation identifier. An address suffix for the synthetic tag address specifies the IPv4 source address, the UDP source port and UDP destination port. Hence, the synthetic tag address enables the destination IPv6 router to send an IPv6 reply packet back to the source IPv6 mobile node via the IPv4 network.

Abstract translation: 源IPv6移动节点被配置为经由与目的地IPv6路由器的IPv4连接来转发IPv6分组。 IPv4分组包括IPv4源地址和目的地址，UDP源端口和UDP目的端口，以及IPv6目的地址字段中的合成标签地址。 合成标签地址（一个有效的（可路由的）IPv6地址保护）具有路由到IPv6路由器的地址前缀。 地址前缀指定转发协议，IPv6路由器的IPv4目的地址和站点级聚合标识符。 合成标签地址的地址后缀指定IPv4源地址，UDP源端口和UDP目的端口。 因此，合成标签地址使目的IPv6路由器能够通过IPv4网络将IPv6应答分组发送回源IPv6移动节点。
