ABSTRACT:
Wireless sensor platforms (10), when deployed, can ascertain whether they can meaningfully participate in communications with more than one cluster (22, 23) of such devices. When true, such multi-cluster platforms can serve as bridge nodes to facilitate the passing of data collected from one cluster to or through another cluster. In a preferred embodiment, the platforms serving as bridge modes (24and25) utilize a communication schedule that imposes no greater work load than the load the platform would otherwise have served as an ordinary node, and preferably the workload is considerably reduced. This aids in ensuring that the portable power reserves of the bridge nodes will support bridge operations for at least as long as the clusters are otherwise functioning.
