A Resource Scheduling Strategy for WSN with Communication Constrained
Due to the loss of wireless communication link,the remote estimator in the wireless sensor network can only receive part of the observation information or can not be completely received,which reduces the accuracy of the state estimation.Focusing on the above problems,a strategy based on network resource scheduling is proposed to improve the impact of link loss on state estimation.The strategy considers the quantization process of sensor observations and the limited transmission bandwidth.The objective of optimization is to minimize the estimated error covariance and the expected energy consumption of the data packet.The data rate and the time slot are allocated to each communication link.The simulation results show that the optimal state estimation of the physical process can be obtained under a small transmission bandwidth and simple BPSK modulation,and the energy consumption of the transmitted data packet can be effectively reduced.
