Redundant, non-overlapping paths or routes for a sensor signal in a mesh network are selected based on predetermined metrics. In one embodiment, a wireless sensor transmits a signal that is received by two separate infrastructure nodes. The signal is retransmitted by the two intermediate nodes via the selected non-overlapping routes to a controller node. Routes are identified for at least two infrastructure nodes that receive signals from an added sensor. Performance metrics are calculated for each route. The two routes with the best performance metrics are selected in one embodiment.
