摘要
在海洋环境监控系统中,针对传感器网络节点能量有限的问题,提出一种二叉树压缩编码算法对原始数据进行压缩,达到节省能耗效果,并引入差分编码来降低传输数据误码率。该算法编程简单,计算量小,易于硬件实现,最后在数学计算和Matlab仿真中验证了其良好的节能效果。
To resolve the limited energy problem of the sensor network nodes in the marine environment monitoring system,the differential encoding is introduced to reduce the bit error rate in the data transmission.A binary tree compressed encoding algorithm is presented.This algorithm which compresses the original data to save energy has some evident advantages,such as easy programming,less computation and convenient realization on hardware.And it achieves a satisfactory result in the mathematical calculations and Matlab simulation.
