摘要:

无线传感器网络中的能量瓶颈可以通过限制通信开销来降低。传感器网络的应用特定信源编码方案利用信源模型、网络体系结构和物理过程中存在的冗余,提供更少的比特来表示相同量的信息。本文报告了各种信源编码方案(无损、有损、恒定比特率、可变比特率、分布式和联合编/解码)的代表性代码在能量消耗、实现的比特率、量化错误/重建错误、编码器-解码器(编解码器)的延迟和复杂度方面的性能。提供了一个可重用的源代码测试框架。最后,我们提出了一组可能的应用程序和合适的源代码,在这些参数。

英文摘要:

The energy bottleneck in Wireless Sensor Network(WSN) can be reduced by limiting communication overhead. Application specific source coding schemes for the sensor networks provide fewer bits to represent the same amount of information exploiting the redundancy present in the source model, network architecture and the physical process. This paper reports the performance of representative codes from various families of source coding schemes (lossless, lossy, constant bit-rate, variable bit-rate, distributed and joint encoding/decoding) in terms of energy consumed, bit-rate achieved, quantization-error/reconstruction-error, latency and complexity of encoder-decoder(codec). A reusable frame work for testing source codes is provided. Finally we propose a set of possible applications and suitable source codes in terms of these parameters.
