摘要
随着学术界对无线传感器网络研究的不断深入,传感器网络节点的定位成为当前的热点。其中主要分为两种类型算法,分别为range-free和range-based。这两种类型的定位算法各有优势和不足之处。为了研究算法发展趋势,文中通过比较几种典型的定位算法,指出了各自的优缺点。最后指出了定位算法的发展趋势:range-based的定位算法比range-free的算法更适合传感器网络小型化、低成本化的需求,应该得到更大的发展。
Because of the development of research on Wireless Sensor Networks (WSNs), localization in WSNs has become a very important research direction. There are two kinds of algorithms, range-based and range-free,which have their own advantages and disadvantages. For the research on the trend of algorithms development ,this paper compares several localization algorithms in WSNs thoroughly and gives analysis .At last we give foretell on localization algorithms in WSNs that range-free is more suit for WSNs than range-based, because of the inevitable trend of minimization and low price of sensor nodes.
