Topology optimization of hierarchical sensor fusion network considering time delay

Abstract

Time delay in sensor fusion is one of the main obstacles to situational awareness and can be mitigated through sensor network planning. This paper deals with topology optimization problem considering time delay in hierarchical sensor fusion network. For this purpose, the network utility maximization (NUM) problem is formulated by quantifying the gain from the information fusion of the local sensor nodes considering the time delay by borrowing the mutual information form, and the centralized optimization is performed using the genetic algorithm.
