A sensor network operates on an infrastructure of sensing, computation, and communication through which it perceives the evolution of events it observes. We propose a fusion-driven distributed dynamic network controller, called MDSTC for a multi-modal sensor network that incorporates distributed computation for in situ assessment, prognosis, and optimal reorganization of constrained resources to achieve high quality multi-modal data fusion. For arbitrarily deployed sensors certain level of data quality cannot be guaranteed in sparse regions. MDSTC reallocates resources to sparse regions reallocation of network resources in this manner is motivated by the fact that an increased density of sensor nodes in a region of interest leads to better quality data and enriches the network resilience. Simulation results in NS-2 show the effectiveness of the proposed MDSTC.
