Abstract
In application of wireless sensor networks( WSNs)
number of data fusion centers and their location have great impacts on performance and lifetime of the network. Propose a distributed algorithm only depends on local connection information
virtual scalar field is constructed by simulating heat conduction process in specific circumstances; by observing gradient lines and extrema
determine the number and positions of data fusion centers.Simulation results show that the suggested positions of fusion centers are near the optimal
and can meet application requirement.
