摘要

在无线传感器网络(WSN)中,许多传感器应用(如监控和监视)可能需要图像传感器阵列进行协同图像传输。由于有限的能量和网络容量,大尺寸图像传输成为无线传感器网络的瓶颈。在本文中,我们提出了一种基于传输路径分集的图像传感器协同传输方案,利用传感器间的相关性来决定传输模式,以达到最小的能量消耗,平衡传感器寿命和所需的图像质量。该优化方案不仅可以使每个图像传感器通过合适的传输路径以节能的方式传输重叠图像的最优部分,还可以通过路径选择和资源分配对重叠图像区域提供不等保护,以获得良好的传输图像质量。仿真结果表明,所提出的图像传输方案在延长网络寿命、减少图像失真和提高能源效率方面取得了显著的效果。

Collaborative Image Transmissions Based on Region and Path Diversity in Wireless Sensor Network
Many sensor applications such as monitoring and surveillance may require image sensor array to conduct collaborative image transmissions in wireless sensor networks (WSN). The large size image transmissions cause bottlenecks in WSN due to the limited energy resources and network capacity. In this paper, we propose a collaborative transmission scheme for image sensors to utilize inter-sensor correlations to decide transmission patterns based on transmission path diversities, which achieves minimal energy consumption, balanced sensor lifetime and required image quality. This optimization scheme not only allows each image sensor to transmit optimal fractions of the overlapped images through appropriate transmission paths in energy-efficient way, but also provides unequal protection on the overlap image regions through path selections and resource allocations to achieve good transmission image quality. The simulation results show that the proposed image transmission scheme can achieve considerable gains in terms of the network lifetime extension, image distortion reduction, and energy efficiency.
