1. Introduction
Wireless Sensor Network (WSN) is a salient technique for information gathering with a wide range of applications including habitat monitoring, battlefield surveillance, intelligent building, etc [1]. In general, the small-sized and battery-powered sensors are deployed and intended to operate unattended for a long operation time. Due to the limitation of battery capacity, the depletion of sensors’ energy may lead to coverage hole and network partition [2]. Recently, the energy harvesting (EH) technology proposes a promising solution to prolong sensors’ lifetime by enabling the sensors to harvest energy from the ambient energy sources, such as thermal, wind and Radio Frequency (RF) [3,4]. The typical application of the Energy Harvesting Wireless Sensor Network (EHWSN) is reported in [5], where Dutta et al. deploy a solar-powered sensor network to monitor the outdoor environment for more than four months. Although, the ambient energy can be harvested and stored for later use, the availability of ambient energy sources is temporally and spatially changing [6,7]. Therefore, the energy harvested and consumed by sensors should be well balanced to promise the sensors’ sustainability and functioning [8].With the emerging of virtual Multiple-Input-Multiple-Output (MIMO), i.e., the cooperative transmission technique, the small wireless devices can distributively coordinate their antennas to emulate the functionality of multi-antenna systems for data transmission [9]. The signals from the small wireless devices are constructively combined at the destination [10]. By exploiting the cooperative transmission in EHWSN, the sensors with low EH capability are able to leverage the energy of other sensors to transmit data, such that sensors’ energy consumption and harvesting can be balanced according to their EH capabilities. Utilizing cooperative transmission in EHWSN, sensors play two energy consuming roles, where one role is to serve as the source with a data packet destined to the sink, and the other role is to serve as the relay to cooperate with the source. Since the energy consumption of cooperative transmission may impact the relay’s operation, the relay selection, i.e., which relay is selected to cooperate with the source, and the power control, i.e., how do the relay and source adjust their transmission power, are both the key issues to make a balanced use of sensors’ energy. Furthermore, due to the decentralized nature of EHWSN, the relay selection and power control should be realized in a distributed manner.
