IMPROVED APIT Algorithm and Its Application in Core Poisoning Systems

摘要：

　　Wireless sensor network (WSN) is widely used in intelligent medical, coal monitoring and etc., and poisoning is one of the most important technologies of WSN.APIT (approximate point in time) is one of the efficient poisoning algorithm in WSN, the advantage of APIT is the localization error rate is lower than other distance-free algorithms, so, we select APIT as the poisoning algorithm in core poisoning system, but according to the special application, there are some disadvantage of APIT algorithm, firstly, the cover rate cant reach 100%; secondly, the core well is a C-shape like distribution instead of a regular rectangle distribution.According to the disadvantages of APIT in core poisoning systems, IMPROVED APIT is proposed in this paper, experimental research shows that IMPROVED APIT algorithm has a lower localization cover rate and a higher cover rate in C-shape distributions compared with APIT algorithm.
