# Power Control Techniques for Interference Management-
## 5 Discussion and Recommendations for Future Study  
This paper has devoted much attention to reviewing the power control literature with a bias on interference management for wireless networks. The authors established that power control in wireless networks is carried out mainly to maintain an acceptable QoS [152; 153], for example, in terms of the SINR or throughput for all devices by minimizing interferences among devices [154], and to optimize energy efficiency, particularly from the user's perspective [155]. Extensive research work related to power control has been carried out. This paper retrieved 770 articles published from 2018 until 2023 from Scopus, WoS, and IEEE Xplore

To address the research questions, we obtained the (1) main information, (2) annual scientific production, (3) most locally cited authors, (4) most globally cited documents, (5) keyword co-occurrence, and trending topic parameters retrieved from the R package software. Even though the authors retrieved many articles, we understand that this review does not exhaust all the work covered in this area but rather highlights some of the contributions made to address interference management through power control techniques. The number of publications published year-on-year provides a reasonable estimate of the current publication trend in a specific field of research. Analyzing the trend in the number of publications can provide information on the probable research trend in future. Table 5 shows, over the years, the number of publications and the distribution of the publications received on power control. The retrieved data show many articles from IEEE Xplore, followed by WoS. Scopus has the lowest record. This influenced the average co-authors' score per document (3.89, lower than those of WoS and IEEE Xplore). The journal with the most published papers was \"_IEEE access_\" in all databases. The highest records publications from Scopus, WoS, and IEEE Xplore were 33, 147, and 330, respectively. The second most popular sources were \"_IEEE transactions on communications_\", \"_IEEE transactions on wireless communications_\", and \"_IEEE open journal of the communications society_\" with records of 8, 44, and 17, respectively. The \"most locally cited authors\" refers to authors cited the most within a specific collection of documents. In the context of this review, we measured how frequently an author in power control techniques has been cited by other authors. Authors whose work has significantly impacted power control techniques are [PERSON] and [PERSON], [PERSON], and [PERSON], respectively, from the Scopus, WoS, and IEEE databases. The IEEE database has the highest record of most local citations per author. We observed that [PERSON] has the highest citation score. Concerning keyword co-occurrence analysis, the results show that there has been significant growth for the \"resource management,\" \"power control\", and \"optimization\" keywords after 2018, indicating their continued relevance in 5G mobile communication. Several factors and trends inform the continued relevance of these keywords in wireless technology. These include the power control and optimization techniques' role in reducing intra-cell and inter-cell interference and optimizing user equipment (UE) power consumption in mobile networks. The authors used the \"most globally cited documents\" from each database to obtain the occurrences of power control techniques. The results show that dynamic power control (DPC) has the highest count. In bibliometric analysis, the high occurrence of an element under study, such as the author's keywords and number of citations, is typically recognized as significant. Thus, this analysis concludes that the research hotspot is in dynamic power control. Likewise, we recommend further research in this area of study. Some recommended techniques for handling interference management and power control in wireless networks have been discussed.
