“…University of Surrey and University of Delft proposed to use commercial application protocol directly on in satellite wireless communications [3][4][5]. And some proposed to realize wireless communication in satellite based on infrared communication [6].Although using the existing commercial protocols can meet the needs of wireless communication in satellite, the commercial protocols have the defects of complicated, large-power, low real-time. Using infrared communication don't have to avoid collision issues by protocol, nevertheless, it constrained the design of the star structure greatly [7].…”
