Abstract: An overlay network, node and application for load balanced service discovery. The application includes the steps of implementing the service discovery mechanism in the DHT P2P overlay network for finding a peer (1100) that provides a desired service; a step of adding to a record structure (50) of the service discovery mechanism a maximum capacity parameter Cmax (54) and a currently used capacity parameter Ccurrent (56); and a step of removing from the tree (10) a record of the peer (1110) that provides the desired service when the currently used capacity reaches a predetermined capacity so that the peer is not contacted by other service clients.

Abstract: A system and method for detecting and locating a radio frequency emitter. A number, N, of receiving units using the same bandwidth, center frequency, and measurement time duration receive signals from the emitter. Higher Order Statistics (HOS) are used to calculate a correlation function between the received signals using one of the received signals as a reference. Results of the correlation function are used to form volumes of probabilities in a subset of an N?1 dimensional space of information regarding the location of the emitter. Each correlation function result in the subset corresponds to a single point in physical space.
