说明：  给出RS编码和译码的原理 以及解决方案，特别是硬件的一种解决方案，值得这一方面的人员研究。(RS gives the principle of encoding and decoding as well as solutions, in particular, a hardware solution, it is this aspect of research staff.)

说明：  Estimating the positions of sensor nodes is a fundamental and crucial problem in ad hoc wireless sensor networks (WSNs). In this paper, an accurate node localization method for WSNs is devised based on the weighted least squares technique with the use of time-of-arrival measurements. Computer simulations are included to evaluate the performance of the proposed approach by comparing with the classical multidimensional scaling method and Cram´ er-Rao lower bound.
