Abstract

A hierarchical wireless sensor network is proposed which separates the sensing ability and routing ability at different layer respectively. It cannot only simplify the hardware design but also can reduce wireless node cost. Also, a mathematical model of data fusion based on hierarchical architecture and Voronoi diagram is given to make sure the connectivity of stochastic sensor nodes and can be more energy efficient. The simulation shows, network communication traffic are cut down sharply, which can reduce nodes energy cost and prolong the lifetime of the sensor network.
