This algorithm firstly uses a heuristic dynamic clustering method to cluster D2D users and those in the same cluster can share the same channel. Then, D2D users in the same cluster are modeled as a non-cooperative game, the expressions of D2D users\u2019 transmission power and energy harvesting time are derived by using the Karush\u2013Kuhn\u2013Tucker (KKT) condition, and the optimal transmission power and energy harvesting time are allocated to D2D users by the joint iteration optimization method. Finally, we use the Kuhn\u2013Munkres (KM) algorithm to achieve the optimal matching between D2D clusters and cellular channel to maximize the total capacity of D2D users. Simulation results show that the proposed algorithm can effectively improve the system performance.<\/jats:p>","DOI":"10.3390\/a12050093","type":"journal-article","created":{"date-parts":[[2019,5,7]],"date-time":"2019-05-07T03:15:46Z","timestamp":1557198946000},"page":"93","update-policy":"https:\/\/doi.org\/10.3390\/mdpi_crossmark_policy","source":"Crossref","is-referenced-by-count":8,"title":["Power Control and Channel Allocation Algorithm for Energy Harvesting D2D Communications"],"prefix":"10.3390","volume":"12","author":[{"given":"Na","family":"Su","sequence":"first","affiliation":[{"name":"Jiangsu Key Laboratory of Wireless Communications, Nanjing University of Posts and Telecommunications, Nanjing 210003, China"},{"name":"Engineering Research Center of Health Service System Based on Ubiquitous Wireless Networks, Nanjing University of Posts and Telecommunications, Ministry of Education, Nanjing 210003, China"}]},{"given":"Qi","family":"Zhu","sequence":"additional","affiliation":[{"name":"Jiangsu Key Laboratory of Wireless Communications, Nanjing University of Posts and Telecommunications, Nanjing 210003, China"},{"name":"Engineering Research Center of Health Service System Based on Ubiquitous Wireless Networks, Nanjing University of Posts and Telecommunications, Ministry of Education, Nanjing 210003, China"}]}],"member":"1968","published-online":{"date-parts":[[2019,5,3]]},"reference":[{"key":"ref_1","doi-asserted-by":"crossref","first-page":"2169","DOI":"10.1109\/COMST.2018.2820069","article-title":"A survey on socially aware device-to-device communications","volume":"20","author":"Ahmed","year":"2018","journal-title":"IEEE Commun.
