近年来，人们对无线传感器网络（WSN）的兴趣越来越大，已经产生了数千篇同行评议的出版物。大多数研究都关注标量传感器网络，测量物理现象，如温度，压力，湿度或位置的对象，可以通过低带宽和延迟容忍的数据流传送。最近，焦点正在转向旨在重新审视传感器网络范例的研究，以实现多媒体内容（如音频和视频流和静止图像）以及标量数据的传输。这一努力将导致分布式，网络化的系统，在本文中被称为无线多媒体传感器网络（WMSNs）。本文讨论了无线多媒体传感器网络在体系结构、算法和协议方面的最新发展和主要研究挑战。在通信协议栈的物理，链路，网络，传输和应用层的现有解决方案进行了研究。最后，基本的开放研究问题进行了讨论，并在这一领域的未来研究趋势进行了概述。
In recent years, the growing interest in the wireless sensor network (WSN) has resulted in thousands of peer-reviewed publications. Most of this research is concerned with scalar sensor networks that measure physical phenomena, such as temperature, pressure, humidity, or location of-objects that can be conveyed through low-bandwidth and delay-tolerant data streams. Recently, the focus is shifting toward research aimed at revisiting the sensor network paradigm to enable delivery of multimedia content, such as audio and video streams and still images, as well as scalar data. This effort will result in distributed, networked systems, referred to in this paper as wireless multimedia sensor networks (WMSNs). This article discusses the state of the art and the major research challenges in architectures, algorithms, and protocols for wireless multimedia sensor networks. Existing solutions at the physical, link, network, transport, and application layers of the communication protocol stack are investigated. Finally, fundamental open research issues are discussed, and future research trends in this area are outlined.
