Abstract: Systems and methods are provided for assigning gateways for heterogeneous wireless mobile networks. A method includes exchanging routing and connectivity information between a plurality of nodes. Each node is respectively included in a corresponding one of a plurality of mobile ad hoc networks. The information excludes global positioning satellite information. The method further includes determining, for a given node, whether a particular set of gateway functionalities of the given node are redundant with respect to one or more other nodes, based on topology information derived from the information. The method also includes dynamically assigning the given node as a gateway or a non-gateway by respectively turning on or turning off the particular set of gateway functionalities of the given node when the particular set of gateway functionalities of the given node are respectively determined to be non-redundant or redundant with respect to the one or more other nodes.

Abstract: Techniques for content management in wireless mobile networks are provided. In one aspect, a method of managing content stored on a plurality of mobile nodes in a mobile ad hoc network (MANET) is provided. The method includes the following step. The content is bound to one or more geographical locations such that, at any given time, the content is stored on at least one of the nodes at the geographical location.

Abstract: Systems and methods for automating the process of recording, indexing, and searching computer activity are provided. Events resulting from computer activities trigger capturing of contents and association of operational contextual information to form a searchable record of activities. The searchable record can be stored in local computer for use by its user, or on server computer, such as can be used for a tutorial by multiple users. Storage management can be used to manage the storage requirements of the captured information forming the searchable record.

Abstract: A method of adapting wireless transmission rates that includes the steps of determining at least a short-term loss ratio for wireless communication during a window of time, and adapting a transmission rate responsive to at least the short-term loss ratio, a maximum tolerable loss threshold for the communication during the window, and an opportunistic rate increase threshold for the communication during the window. A size of the window, the maximum tolerable loss threshold, and the opportunistic rate increase threshold are responsive to the transmission rate used for the communication. Preferably, the window is re-started if the transmission rate changes. Also, systems, devices, and memories that embody the foregoing.
