Show moreA peer-to-peer (P2P) file sharing system is provided with an enhanced search method for a client node therein. A search from the client contains a primary search of metadata words and a secondary search of content file keys taken from the primary search results. The results of the secondary search are then used to rerank the results of the primary search before the client displays the results of the search to the user. Metadata distribution schemes can also be used to further enhance the utility of the system. Enhanced P2P file searching accuracy is thus provided. Applications for selective peer-to-peer communication may further be employed.

Show moreAn intranet mediator for obtaining direct answers to natural language questions allowing users to search both a data warehouse of integrated/structured data sources and unstructured data sources. The intranet mediator allows the user to obtain an answer to a natural language question without having to surf the data sources in which the answer might be contained, or without being limited to one specific factual item return. The intranet mediator operates on the supposition that most answers to business queries are contained within structured data sources which have been integrated into the data warehouse thereby having common schema and known contents. Preselection of the most relevant data source(s) is thus possible before query output. Search of unstructured data is also performed for additional context surrounding either the question or the answer. A direct answer is given in response to the question. If desired, the intranet mediator may also display a list of data sources where additional relevant information may be found.

Show moreThe invention disclosed is a process to allocate channels in a sectorized cellular network. A system of allocating cellular frequencies (channels) to the sectors among the cells within a tile is disclosed which maximizes channel set usage within the tile while avoiding co-channel interference between cells. According to the present system, no infrastructure rebuild is required. The disclosed approach further supports all currently used cellular technology. By alternating and rotating the channel assignments across sectors, what is a seemingly locally poor algorithm utilizing additional local channels is actually a globally good algorithm which is efficient in terms of the total number of channels used owing to short reuse distance and low number of cell types.

Show moreThe invention disclosed is a process to allocate channels in a sectorized and tiered cellular network. A system of allocating cellular frequencies (channels) to the sectors among the outer tier of cells within a tile is disclosed which maximizes channel set usage within the tile while minimizing co-channel interference between cells. Any unused, or remaining, frequencies for the outer tier of that cell may then be allocated to an inner tier of the cell that has not had a channel allocated thereto. No additional infrastructure or maintenance set-up is required under this technique for allocating the channel to the additional transceiver and a very high degree of channel utilization is achieved.

Show moreAn algorithm on a computer readable medium for efficiently creating a message efficient virtual backbone in a wireless ad hoc network utilizes three phases to establish an efficient network among the independent transceivers of a wireless ad hoc network. Independent transceivers within the transmission range of each other are neighbors. A leader election and tree construction phase constructs a tree of neighboring transceivers with one transceiver being designated the root and with each transceiver establishing and recording its location in the tree structure and the identifiers of its neighbors; and reporting when the tree is established. A level calculation phase determines the level of each transceiver away from the root transceiver, with each transceiver recording the level of its neighbors. Precedence for each transceiver is established with consideration of each transceiver's tree level and identifier, with tree level being paramount in deciding precedence; and reporting when the levels of the tree are established. A backbone construction phase establishes all transceivers as a dominator or a dominatee, with the dominators forming the network backbone and the dominatees all being neighbors to a dominator. Within the network each transceiver only needs to know the information of its neighboring transceivers.
