Wireless sensor networks prototype system for PHM
Jie Zhang, Bo Jing, Liming He · 2010
A prototype system for wireless sensor networks is brought forward to provide a dependable test-bed which has enable continuous advancements in the practice of prognostics and health management (PHM). The connection and overlay model of network nodes is advanced to realize the minimal cost in the scale-free network topology. According to the energy usefulness, the dynamic non-average-slot MAC protocol and scale-free single-multi hop routing protocol are designed to availably organize the network. In order to achieve the monitor information, management and decision-making on resource shareing, sink node is regarded as web server which connects Ethernet. Finally, the rationality and credibility of the prototype system are validated through functional experiment.
