Fusion center positioning algorithm for WSNs based on virtual scalar field
Da‐Ke Gu · Transducer and Microsystem Technologies · 2015
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.
