In this review article, we aim to describe recent advances in compressive sensing-based data aggregation techniques in wireless sensor networks, including current research efforts, challenges, and research trends. Sparse and compressible signals are present in many applications of sensor networks, such as environmental monitoring and vehicle surveillance. Compressive sensing has many properties such as simplicity of sensing and compression operations, universality, and an acceptable decrease in the quality of signal reconstruction, which makes it attractive for use in sensor networks. Packet drops do not damage the network as much as other protocols, and only for each measurement that does not reach the sink will cause a slight decrease in the quality of signal reconstruction. We begin the discussion with a brief introduction to compressive sensing theory and then describe the use of this technique in wireless sensor networks. Finally, the research issues and challenges ahead are discussed to provide a perspective for future research
