Method for coordinating access points of an optical wireless network using a selected heuristic, and associated coordination device

A coordination device for coordinating at least two access points having respective coverage areas each subdivided into an exclusive sub-area supplemented by at least one interference sub-area where they overlap and forming part of an optical wireless network, said device comprising at least one processing unit and at least one memory adapted to allocate to said access points time slots of a time channel during which they are adapted to transmit at least to interface devices each located in at least one of their coverage areas and respectively coupled to communication devices,

• wherein for each time channel created, said processing unit and said memory are dedicated to:
• a) allocating to each interface device located in an exclusive sub-area of an access point a free time slot of the latter in said time channel, and then
• b) as long as there remains at least one interface device located in an interference sub-area and without an allocated time slot, for each free time slot of said time channel,
• determining a first set of interface devices compatible with the considered free time slot, then
• if said first set is non-empty, allocating to an interface device that it comprises the considered free time slot which is compatible with an available access point according to a chosen heuristic, or if said first set is empty, considering the considered free time slot as not free, then
• performing again said b) if there is still a free time slot of said time channel.
