Comparison of throughput and robustness in the WPCN under Algorithm 1, improved -medoids algorithm, improved hierarchical algorithm, the energy threshold approach 1, the energy threshold approach 2, and the energy threshold approach 3. In the three energy threshold approaches, the number near the point represents the value of . In the other three clustering algorithms, the number near each point represents the value of .
