In this thesis, a set of three media access control (MAC) schemes for an indirect diffused light free-space optical communications (ID-FSOCs) are proposed. ID-FSOC has been recently proposed to establish wireless high-speed (i.e., greater or equal to 1 Gbps) network access using FSO from stations that have no line-of-sight (LOS) with the access point. ID-FSOC employs a diffuse reflector (DR) to uniformly reflect diffused light from an incident laser to all directions, except towards the DR. To establish a link, ID-FSOC requires LOS between the transmitter and the DR and between DR and the receiver. In this way, ID-FSOC relaxes the location of stations as long as they keep LOS to the DR.
