摘要： As multicast services become prevalent, it is important to find viable solutions for multicasting to mobile nodes. This problem is complicated by the necessity to support multicast services over existing backbone and access networks that may have varying network and/or link layer multicasting capabilities. While most work on supporting multicast services focuses on the IP layer solution, the present invention presents an application-layer approach for providing multicast services to mobile users traversing networks with diverse multicast capabilities. The present invention places multicast proxies in the backbone and access networks to support several multicast-related functions at the application layer including the creation of virtual networks for dynamically tunneling through non-multicast-capable networks.

摘要： A hybrid mobile ad-hoc network and a method of operating the same, including a mobile network node and a plurality of static network nodes randomly distributed over a coverage area with a predetermined density. The static network nodes form a static infrastructure backbone of the hybrid mobile ad-hoc network. Position information of the static network nodes, either through position awareness or triangulation with reference to other static nodes enhances the network function. The method tracks mobile node position with a minimum of overhead because of the fixed infrastructure of static nodes. The infrastructure can self-heal by placing excess static nodes in a hibernating state, and activating those in response to the failure of a nearby static node.

摘要： A method and system for providing location-aware and location-based content services. The system preferably comprises an overlay service network that includes a plurality of information gateway servers. A mobile client uses the servers in the overlay service network to request and receive information. The particular server used by the mobile client is selected based on the geo-location of the mobile client. The method comprises partitioning a geographic area into a plurality of sub-areas and associating resources to the sub-areas based on the location of mobile units within a sub-area.

摘要： Disclosed is an improved proactive location based routing protocol for ad-hoc wireless networks. When a source node has a data packet to send to a destination node, the source node calculates an estimated future location of the destination node prior to forwarding a data packet to the destination node. The estimated future location may be based on the last known location, velocity and bearing of the destination node, as well as upon the estimated propagation delay (i.e., the estimated time it will take the data packet to reach the destination node after being transmitted by the source node). The source node routes the data packet by identifying which one of a plurality of its neighbor nodes is closest to the estimated future location of the destination node, and routes the data packet the identified neighbor node as an intermediate node along the route from the source node to the destination node. Further, the frequency of flooding broadcasts is based on the velocity of the network nodes. As the velocity of a network node increases, the rate at which the node broadcasts its location and mobility data also increases. The broadcast frequency of a network node may be dynamically adjusted as its velocity changes.

摘要： A plurality of servers for processing client requests forward the requests among themselves to achieve a balanced load. When a server initially receives a client request, it randomly selects another of the plurality of servers, referred to as a first-chance server, and forwards the request to this server. Upon receiving the request, the first-chance server determines if it is overloaded and if not, processes the request. However, if overloaded, the first-chance server compares its load to the load of one or more predetermined next-neighbor servers. If the next-neighbor server(s) are more loaded than the first-chance server, the first-chance server processes the request. Otherwise, the first-chance server forwards the request to the least loaded next-neighbor server. The next-neighbor receiving the request either processes it directly, or alternatively, based on its current load and that of its next-neighbor server(s), forwards the request to another next-neighbor server for processing.
