This work investigates the robust beamforming for a multi-antenna internet of things (IoT) system using wireless information and power transmission (WIPT), given that imperfect channel state information (CSI) assumption is accounted. In particular, we investigate the problem of maximizing the worst-case energy harvested, taking into account the quality of service (QoS) constraint of user rate.

This paper presents a solution to the power balance control strategy for WSN with collaborating heuristic. A distance between the weight factors and obtained nodes interference value is used to establish a useful interference model for enhancing the signal-to-interference-noise ratio (SINR). The utility function of the nodes residual energy and transmission rate is modeled by apply heuristic strategy. The optimal transmission power is obtained after several iterations of the heuristic algorithm.
