Data integration and network optimization play an important role in wireless sensor network which is data-centric. Network coding has been used as an efficient method to improve network throughput over wireless environments. The problem of broadcasting K different contents to D destinations from N sources in wireless network was considered. A dynamic control scheme that allows sources split traffic was proposed. The scheme adjusts the traffic based on the utility function to increase the number of coding opportunities. The theoretical analysis and simulation results show that the proposed scheme is stable and effective.
