1) Architecture of a global mesage network employing low earth-orbiting satellites :We have presented a concept of a global message network, catering to low density traffic from user terminals, using a constellation of low-altitude astellites. Under low traffic, performance measures are estimated.2) Communication structure of group works through global communication networks :2.1) We have proposed a new architecture of a copy network which employs the principle of recursive generation of copy cells.2.2) We have proposed a new algorithm, called PCRA, which can be implemented in a Q-channel connection request environment, where Q>3.3) Modeling and analysis of group works through a global message network :We have presented a global message network employing low earth-orbiting satellites to collect information from finite users in a restricted area. We have shown useful transmission rate to get maximum successful transmissions within a period.
