Show moreA method in a data processing system and apparatus for organizing files, web pages, or web site members organized in a traditional first hierarchical file structure that is on a recordable medium of a data processing system. A user-defined metalabel is assigned to each of the electronic files, web pages, or web site members. The electronic files, web pages, or web site members are organized as a function of the metalabels into a second hierarchical file structure existing simultaneously with the first hierarchical file structure on the recordable medium of the data processing system. The files, web pages, or web site members can be organized or grouped by the metalabels for efficient searching or following conversations of group members on social networking sites.

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 moreAn optimized document-indexing device is based on a pruned inverted index structure mapped to hardware. The device can be accommodated on a single chip and can be reprogrammed to accommodate index structures of different lengths and support varied posting-list sizes and varied term list sizes, thus sustaining high reusability and efficiency for a single device. The device can be used either as an internal slave component or as an external co-processor. The device controllers are efficient in resource demands and take only a minimal percentage of the logic and memory space of the hardware device.

Show moreA peer-to-peer (P2P) file sharing system is provided with an enhanced search method for a client computer therein. The method includes masking at least one term in a multi-term query entered into a client computer of the P2P system to obtain a masked query and routing the masked query to a plurality of server computers. The masked query is compared to a file descriptor of server files in each of the plurality of server computers to identify a plurality of matching server files. The server computers return to the client computer as search results the file descriptor and a mathematical identifier for each of the plurality of matching server files. The server computer may return to the client computer only a subset of the plurality of the matching server files. Enhanced P2P file searching accuracy is provided.

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.
