To address this, a scalable DRL framework using A2C, PPO, and DQN is proposed for traffic-aware RMSA and proactive defragmentation.<\/span><\/p>\n<p style=\"text-align: justify;\"><span style=\"font-size: 18px; font-family: 'Times New Roman';\">Results showed up to 61.63% SBR improvement over SP-FF, with 95% confidence intervals confirming improved scalability, spectral efficiency, and overall performance compared with conventional methods.<\/span><\/p>\n<p>[\/vc_column_text][\/vc_column][\/vc_row][vc_row][vc_column width=&#8221;1\/2&#8243;][vc_single_image image=&#8221;6703&#8243; img_size=&#8221;full&#8221; css=&#8221;&#8221;][\/vc_column][vc_column width=&#8221;1\/2&#8243;][vc_single_image image=&#8221;6704&#8243; img_size=&#8221;full&#8221; css=&#8221;&#8221;][\/vc_column][\/vc_row][vc_row][vc_column width=&#8221;1\/2&#8243;][vc_single_image image=&#8221;6705&#8243; img_size=&#8221;full&#8221; css=&#8221;&#8221;][\/vc_column][vc_column width=&#8221;1\/2&#8243;][vc_single_image image=&#8221;6706&#8243; img_size=&#8221;full&#8221; css=&#8221;&#8221;][\/vc_column][\/vc_row]<\/p>\n<\/div>","protected":false},"excerpt":{"rendered":"<p>[vc_row][vc_column][vc_column_text css=&#8221;&#8221;] On Tuesday, March, 3rd ,2026 the department of Communication and Information engineering at Al-Khwarizmi &#8230; <a class=\"cz_readmore\" href=\"https:\/\/en.kecbu.uobaghdad.edu.iq\/?p=6701\"><i class=\"fa czico-132-arrows-8\" aria-hidden=\"true\"><\/i><span>more<\/span><\/a><\/p>\n","protected":false},"author":27,"featured_media":6703,"comment_status":"closed","ping_status":"closed","sticky":false,"template":"","format":"standard","meta":{"_lmt_disableupdate":"","_lmt_disable":"","footnotes":""},"categories":[3,8,1],"tags":[],"class_list":["post-6701","post","type-post","status-publish","format-standard","has-post-thumbnail","hentry","category-latest-news","category-masters-discussions","category-uncategorized"],"yoast_head":"<!-- This site is optimized with the Yoast SEO plugin v25.8 -
