LEO satellite communication networks—a routing approach [PDF]
Wireless Communications and Mobile Computing, 2003 AbstractIn the modern world of telecommunications, the concept of wireless global coverage is of the utmost importance. However, real global coverage can only be achieved by satellite systems. Until recently, the satellites were in geostationary orbit and their high altitude could not allow real‐time communication such as cellular networks.
