A managed wireless mesh for infrastructure-level, stable regional mesh network has been studied. NerveNet, which we have been proposing, is a concept of future regional platform network that covers local regions and provides various context-aware services with the shared use of sensors and actuators. The managed wireless mesh developed for materializing NerveNet features auto-configuration of multiple, different routes between any two base stations for high capacity and reliability. The managed wireless mesh of ten base stations was implemented on PCs with commercial L2 switches. Performance evaluation showed that route switching after a link failure had been detected was completed in no later than 70 milliseconds while it takes a few to tens of seconds with existing ad hoc routing-based mesh networks.
