Abstract:
In order to increase the communication efficiency in distributed data association,this paper proposes an improved algorithm on its information propagation method.Based on the distributed calculation,this paper replaces transforming messages to every neighbour node by broadcasting a shared belief,and modifies the means of information expression and propagation,reducing communication volume greatly.The logarithmic operation is introduced during realization and the stability of numerical computing is solved.The simulation results indicate that this algorithm saves energy resources,increases the network’s using life and implements network size’s scaling easily.The simulation results are consistent with the theoretical analysis.
