Optical Wireless Mesh Network In the earlier sections, we discussed the attributes and
shortcomings of optical wireless as well as the attributes and shortcomings of wireless
mesh networks. When the attributes and shortcomings of the two technologies are put
together, they are ideally matched in that an attribute of one complements a shortcoming
of the other. We start by discussing the shortcomings of wireless mesh networks
and how FSO complements them.
?– Latency and jitter In a mesh network, data traffic has to hop through several
nodes as it is routed through the network. At each node, the traffic experiences
certain forwarding delays. Therefore, the total end-to-end delay experienced by the
traffic within the mesh network may add up to be significant and unacceptable for
certain applications. Additionally, if the forwarding delay is not constant at each
hop (as in the case of PtM mesh networks), the traffic may also experience significant
amounts of jitter. However, FSO links add virtually no delay, especially when
compared with most other wireless solutions.
