Since traditional wireless sensor networks (WSNs) cannot fully meet the requirements of comprehensive environment monitoring of underground coalmines, wireless multimedia sensor networks (WMSNs), enabling the retrieval of multimedia information, are introduced to realize fine-grained and precise environment surveillance. In this paper, a framework for designing underground coalmine WMSNs based on Multi-Band Orthogonal Frequency-Division Multiplexing Ultra-wide Band (MB-OFDM-UWB) is presented. The selection of MB-OFDM-UWB wireless transmission solution is based on the characteristics of underground coalmines. Network structure and design challenges are analyzed first, which is the foundation for further discussion. Then, key supporting technologies and open research areas in different layers are surveyed, and we provide a detailed literature review of the state of the art strategies, algorithms and general solutions in these issues. Finally, other research issues like localization, information processing, and network management are discussed.<\/jats:p>","DOI":"10.3390\/s16122158","type":"journal-article","created":{"date-parts":[[2016,12,16]],"date-time":"2016-12-16T10:55:28Z","timestamp":1481885728000},"page":"2158","update-policy":"https:\/\/doi.org\/10.3390\/mdpi_crossmark_policy","source":"Crossref","is-referenced-by-count":14,"title":["MB-OFDM-UWB Based Wireless Multimedia Sensor Networks for Underground Coalmine: A Survey"],"prefix":"10.3390","volume":"16","author":[{"ORCID":"https:\/\/orcid.org\/0000-0001-5440-4906","authenticated-orcid":false,"given":"Ruisong","family":"Han","sequence":"first","affiliation":[{"name":"School of Electronic and Information Engineering, Beijing Jiaotong University, Beijing 100044, China"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Wei","family":"Yang","sequence":"additional","affiliation":[{"name":"School of Electronic and Information Engineering, Beijing Jiaotong University, Beijing 100044, China"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Kaiming","family":"You","sequence":"additional","affiliation":[{"name":"School of Electronic and Information Engineering, Beijing Jiaotong University, Beijing 100044, China"}],"role":[{"role":"author","vocabulary":"crossref"}]}],"member":"1968","published-online":{"date-parts":[[2016,12,16]]},"reference":[{"key":"ref_1","unstructured":"State Administration of Work Safety, and State Administration of Coal Mine Safety State Technological Development Programming of Work Safety: Coal Mine Domain Research Bulletin (2004\u20132010), Available online: http:\/\/www.chinasafety.gov.cn\/file\/2004-01\/kjgh-3.doc."},{"key":"ref_2","first-page":"506","article-title":"The theories and key technologies for the new generation mine wireless information system","volume":"29","author":"Yang","year":"2004","journal-title":"J.
