煤矿安全生产是一项重中之重的工作，对保障、支撑和促进煤炭工业可持续发展具有重要作用。传统的无线传感器网络不能完全满足煤矿井下环境综合监测的要求，引入无线多媒体传感器网络（WMSNs）实现对多媒体信息的检索，以实现对环境的细粒度、精确监测。提出了一种基于多带正交频分复用超宽带（MB-OFDM-UWB）的煤矿井下无线多媒体传感器网络的设计框架。根据煤矿井下的特点选择MB-OFDM-UWB无线传输方案。首先分析了网络结构和设计挑战，这是进一步讨论的基础。然后，关键的支撑技术和开放的研究领域在不同的层面进行了调查，我们提供了一个详细的文献综述的最先进的战略，算法和一般解决方案在这些问题。最后，其他研究问题，如本地化，信息处理和网络管理进行了讨论。
Safety production of coalmines is a task of top priority which plays an important role in guaranteeing, supporting and promoting the continuous development of the coal industry. 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.
