摘要： The present invention relates to a distributed transmission and reception system, and an expanded wireless network. The distributed transmission and reception system according to one embodiment of the present invention comprises a distributed transmission system, a distributed reception system, and a distributed relay system. A source signal of a source radio is divided into a plurality of signals through the distributed transmission system, is relayed through an associate's radio, and can be distributed into and transmitted to other networks which are located out of a distance range. A destination radio positioned in another network can restore the original signal of the outgoing radio with the help of relay from the associate's radio via the distributed reception system. The associate's radio providing help in relay amplifies only a part of the source signal, and thus the intensity of the signal can be enhanced. Accordingly, when the outputs of associate's radio providing help in relay are combined, the combined associate's radio function as a high-power radio, and thereby having a greater capability than the original distance range capability. When a distributed transmission system and a distributed reception system operate within one network, a distributed relay system is constructed. The distributed relay system relays a signal arriving at another network to be transmitted to yet another network, thereby consequentially, expanding a wireless network area.

摘要： The present invention relates to a bio-inspired distributed wireless resource allocation, and a method of solving a conflict of a firing phase allocation in the bio-inspired distributed wireless resource allocation includes (a) selecting a reference firing phase having a preset degree of allocation-available space, on the basis of firing phase allocation information within a received firing message, when a newly-entered node attempts the firing phase allocation, (b) calculating changeable positions of the reference firing phase and a succeeding firing phase of the reference firing phase under assumption set based on the firing phase allocation information, and (c) setting a space between the changeable positions as an allocation-available range and allowing the newly-entered node to be allocated with an arbitrary firing phase within the allocation-available range.

摘要： A method and system are provided for tagging, indexing, searching, retrieving, manipulating, and editing video images on a wide area network such as the Internet. A first set of methods is provided for enabling users to add bookmarks to multimedia files, such as movies, and audio files, such as music. The multimedia bookmark facilitates the searching of portions or segments of multimedia files, particularly when used in conjunction with a search engine. Additional methods are provided that reformat a video image for use on a variety of devices that have a wide range of resolutions by selecting some material (in the case of smaller resolutions) or more material (in the case of larger resolutions) from the same multimedia file. Still more methods are provided for interrogating images that contain textual information (in graphical form) so that the text may be copied to a tag or bookmark that can itself be indexed and searched to facilitate later retrieval via a search engine.
