Abstract: Systems (100) and methods (500) for searching electronic documents. The methods comprise: using first electronic documents to derive topics respectively defined by sets of words; using the topics to transform a format of known subject reviews and written pieces from a textual format to a numerical format in which each of the subject reviews and written pieces is expressed as a topic vector containing a plurality of first numbers respectively corresponding to the topics; generating concept vectors by transforming a domain of the topic vectors from a first numerical domain to a second different numerical domain; and determining similarities between the known subject reviews and the written pieces by comparing first concept vectors that are associated with the known subject reviews to second concept vectors concept vectors that are associated with the written pieces.

Abstract: A mobile ad hoc network includes a plurality of wireless mobile nodes and a plurality of wireless communication links connecting the plurality of nodes together. The method of tracking traffic includes each node monitoring traffic communicated between nodes in the network, each node generating traffic information based upon how much traffic is being communicated between various nodes in the network, and each node storing the traffic information in a traffic database. The traffic information may be based upon bandwidth and may include at least one of error rate, end-to-end delay, end-to-end delay variation, hop count, expected path durability, and priority. Each node may discover and select traffic routes based upon the stored traffic information.

Abstract: A mobile ad hoc network includes a plurality of wireless mobile nodes and a plurality of wireless communication links connecting the plurality of nodes together over a plurality of channels. The method includes each node monitoring link performance on a first channel, link performance being based upon at least one quality of service (QoS) threshold, and each node scouting one or more other available channels when the monitored link performance on the first channel falls below the QoS threshold. The QoS threshold is preferably based upon at least one of available bandwidth, error rate, end-to-end delay, end-to-end delay variation, hop count, expected path durability, and priority.

Abstract: The mobile ad hoc network includes a plurality of wireless mobile nodes and a plurality of wireless communication links connecting the plurality of nodes together. The method includes transmitting quality-of-service (QoS) route requests to discover traffic routing based upon a QoS parameter, each node calculating a node QoS tag value to make traffic admission control decisions, the node QoS tag value being a function of at least one node specific QoS metric, and each node determining whether to admit traffic in response to QoS route requests based upon the calculated QoS tag value and the QoS parameter of QoS route requests.

Abstract: The method includes transmitting a quality-of-service (QoS) route request to discover routing based upon a QoS parameter, and the route request including a flow identifier and a QoS link metric. Furthermore, the method includes each intermediate node determining whether the node can support the requested QoS parameter and, if so, updating the QoS link metric, forwarding the QoS route request, and temporarily reserving node resources. The destination node, upon receiving the QoS route request, generates a reply including the flow identifier and updated QoS link metric for each discovered route, and the source node generates QoS route metrics based upon updated QoS link metrics in the replies. Also, the source node selects a route to the destination node based upon the QoS route metrics, and transmits route confirmations to intermediate nodes on the selected route.
