A wireless sensor network (WSN) includes a sensor node cluster having a plurality of sensor nodes positioned along a section of a pipeline; a base station; a designated cluster head for the sensor node cluster, the designated cluster head configured to forward sensor data packets towards the base station; and a server having circuitry. The circuitry is configured to determine when the designated cluster head has a battery energy level below a predetermined level, elect a replacement cluster head for the designated cluster head when the battery energy level is below the predetermined level, and forward an energy status of the designated cluster head to the replacement cluster head.

A room temperature nitrogen dioxide gas sensor comprising tin(IV) oxide decorated with gold nanoparticles is described. The tin(IV) oxide may have an average layer thickness of 10-1,000 nm, and is topped with dispersed gold nanoparticles having an average longest dimension of 200-650 nm. The room temperature nitrogen dioxide gas sensor may be used to detect and measure levels of nitrogen dioxide gas at room temperature and at concentrations of 100 ppb-1800 ppm, with a high stability. A method of making the room temperature nitrogen dioxide sensor is also described, and involves sputtering to deposit a tin(IV) oxide layer and a gold layer on a substrate, followed by annealing.

Node placement for pipeline monitoring

The present disclosure relates to a clustering approach for sensor nodes of a wireless sensor network. This clustering approach, equal distance different members, balances the power burden amongst sensor nodes by deriving an optimal number of sensor nodes at each segment of a length. To this end, the present disclosure describes a linear wireless sensor network wherein the distance between adjacent cluster heads is equal while the number of and distance between sensor nodes in each cluster is different. A power consumption model is derived to aid in the determination of the optimal number of sensor nodes within each cluster. Following evaluation of the cluster approach in comparison with previously described approaches, the present disclosure is observed to improve network longevity and reduce power consumption by deliberately increasing the density of sensor nodes nearest a base station.
