在无线传感器网络中，传感器节点传输的数据容易受到噪声信道等因素引起的误码破坏。因此，有必要提供适当的差错控制方案来降低误码率。由于传感器网络中严格的能量约束，使用能量高效的差错控制方案至关重要。本文重点研究了各种差错控制码在不同平台上的误码率性能和功耗性能。具体实现了不同约束条件下的差错控制码，并用VHDL语言进行了仿真。在FPGA和ASIC设计上进行了实现，并对功耗进行了测量。通过通过高斯信道传输随机生成的数据，根据误码率(BER)来评估这些码的差错控制性能。通过对三种不同的差错控制码的研究和比较，我们发现采用ASIC实现的二进制BCH码最适合于无线传感器网络
In wireless sensor networks, the data transmitted from the sensor nodes are vulnerable to corruption by errors induced by noisy channels and other factors. Hence it is necessary to provide a proper error control scheme to reduce the bit error rate (BER). Due to the stringent energy constraint in sensor networks, it is vital to use energy efficient error control scheme. In this paper, we focus our study on the performance analysis of various error control codes in terms of their BER performance and power consumption on different platforms. In detail, error control codes with different constraints are implemented and simulated using VHDL. Implementation on FPGA and ASIC design is carried out and the energy consumption is measured. The error control performance of these codes is evaluated in terms of bit error rate (BER) by transmitting randomly generated data through a Gaussian channel. Based on the study and comparison of the three different error control codes, we identify that binary-BCH codes with ASIC implementation are best suitable for wireless sensor networks
