This volume includes the papers presented at the 20th International Conference on Advances in Mobile Computing & Multimedia Intelligence (MoMM2022), organized in conjunction with 24th International Conference on Information Integration and Web Intelligence. The dominant research focus of submitted papers was artificial intelligence and machine learning. The accepted papers presented advances and innovations in an array of areas such as online teaching, activity and movement detection, greenhouse gas emission, smart irrigation, network security, and video delivery. MoMM2022 attracted 34 papers, from which the Program Committee selected 8 regular papers and 8 short papers. Due to safety concerns as well as other restrictions preventing travel and gatherings, it was decided to organize MoMM2022 as a virtual conference.
