Bootstrapping free-space optical networks [PDF]
IEEE Journal on Selected Areas in Communications, 2005 We introduce a challenging problem in establishing and initially configuring a free space optical (FSO) network. In such networks, it is assumed that each communication node is a base station, including a router and optical transceivers, and its number of transceivers is limited.
