A method of distributed control of a wireless mesh network without knowledge of global topology. The method includes: a station joining the network with any current member by propagating the join-request, or two meshes merging using the steps of: one mesh joining the other as a whole and then re-synchronizing its timing. The method further includes: first, each station periodically transmits a beacon; second, in response to a beacon being no longer detected, a station transmitting a bitmap of stations that it can still receive; third, each station responds by adding stations that it can receive with all of the bitmaps received from other members, and retransmitting the updated bitmap; fourth, after time for all stations to respond, all stations base current membership on the bitmap. The method further includes: determining sharable time slots that will not interfere with neighbors or other slot sharers, using and then releasing those slots.

To identify a fault location easily if there is any fault detected in a network. If an optical path is switched from a working system to an auxiliary system due to a fault, an optical test signal originated from a network node apparatus located at an end point of the optical path is looped back by another network node apparatus on the optical path for the working system. This looped back optical signal is received by the network node apparatus of an originator, in which the signal quality of the optical test signal is measured by a determination device, thereby detecting the presence or absence of the fault on the path through which the optical test signal has been passed. A test receiver within the determination device measures a BER, an S / N ratio, an optical power, or an optical wavelength, whereby it is possible to detect not only the fault location due to disconnection of a link but also degradation in the signal quality.
