矿井下无线多媒体传感网络图像的簇间多跳传输

With the complexity and change of the environment monitoring increasing, the simple data obtained from the traditional sensor network have been unable to satisfy the full requirements of environmental monitoring of people. It is an inevitability that the rich information such as images, audio, video and other media will be needed urgently in environmental monitoring activities based on sensor network. The study of how to enhance the efficiency of transmitting the multimedia data by wireless multi-hop and to extend the life cycle of network has become a hot spot. This paper, starting from the power consumption, combining with the characteristic of underground roadway;To improve the sub-cluster-style chain cluster multi-hop transmission proposed by others has come up with a new inter-cluster multi-hop transmission scheme, which idea is to divide the area of cluster, as well as the number of nodes distributed in each area that can not equal to be used and the DCHS is used in choosing the cluster head; The results indicate that this image transmission can extend the life cycle of network and reduce the power consumption by the MATLAB simulator.
