Abstract:
A method for transmitting information in a wireless modem network, said wireless modem network having a plurality of wireless modems, comprising:classifying said plurality of wireless modems into a plurality of groups; selecting a plurality of group masters by choosing said plurality of wireless modems that are respectively associated with said plurality of groups, said group masters being chosen by selecting said wireless modems having a maximum average signal intensity to said plurality of wireless modems within said group enclosing said group master; transmitting information and then writing said information to an interior header of a plurality of interior headers by a first wireless modem of said plurality of wireless modems, said plurality of interior headers recording whether said plurality of wireless modems within a first group receive said information from said plurality of wireless modems within said first group; transmitting said information to a first group master of the first group of said first wireless modems and then writing said information to said interior header when said first wireless modem is not one of said plurality of group masters; transmitting said information to a second group master when one of said plurality of group masters has not received said information, said second group master being farthest from said first group master; writing said information to a first exterior header of said first group master and a second exterior header of said second group master, said exterior headers being used to record whether said plurality of group masters receive said information; transmitting said information to a group master among said plurality of group masters that is farthest from a source transmitting said information and then writing said information to said exterior header of said group master that is farthest from a source transmitting said information when one of said plurality of group masters has not received said information; building a plurality of communication chains between a first portion of said plurality of wireless modems and a second portion of said plurality of wireless modems according to a rule until said plurality of wireless modems have said plurality of communication chains, wherein said first portion constitutes said plurality of wireless modems that have not received said information and, said second portion constitutes said plurality of wireless modems that have received said information, and said rule stops building a communication chain, if said communication chain interferes with any of said plurality of communication chains; and transmitting said information from said second portion of said plurality of wireless modems to said first portion of said plurality of wireless modems.
