Abstract
A computer-implemented method includes arranging two or more sensor nodes into a ring monitor. Each sensor node of the ring monitor is coupled to a sensor and cross-monitors at least one other sensor node in the ring monitor. A request is received to add a new sensor node. A spatial partitioning of a plane is generated, by a computer processor, representing locations of the new sensor node and the two or more sensor nodes in the ring monitor. The spatial partitioning includes a plurality of regions, each region corresponding to a sensor node. Two or more adjacent sensor nodes are selected from the two or more sensor nodes in the ring monitor, based at least in part on the spatial partitioning. The two or more adjacent sensor nodes are instructed to monitor the new sensor node, which is instructed to monitor each of the two or more adjacent sensor nodes.
