Abstract:

A scheduling mechanism is presented based on energy-varying and detecting-probability in sensor networks. It ensures the relatively uniform energy consumption among nodes during the scheduling by adjusting the scheduling period according to the amount of the energy-varying in nodes, and simultaneously fulfils the uniform distribution of the scheduled nodes by adopting the distribution scheduling based on the local information of nodes in networks. Taking the distribution of the practical information in survey area into account, the mechanism enhances the accuracy of the collected information by introducing the detecting-probability model in networks nodes and guarantees the services degree for application. The superiority and reliability of the mechanism are testified in theoretic analysis and simulation experiment.
