物联网搜索引擎是物联网的重要组成部分,有效实时的搜索引擎是物联网实现物与物相连的关键。本文从Dyser机制出发,对其中的3种预测模型——APM、SPPM、MPPM从通信开销上进行对比研究,得出了有益的结论,并在此基础上提出了一种基于MPPM的改进预测模型。经测试证明:改进算法在通信开销上得到了有效降低且一定程度上提高了准确性。
Internet of Things search engine is an important part of the Internet of Things, an effective real-time search engine is the Internet of Things to achieve the key to the connection. In this paper, starting from the Dyser mechanism, this paper makes a comparative study on the three kinds of prediction models - APM, SPPM and MPPM from the communication overhead, and draws useful conclusions. Based on this, an improved MPPM-based prediction model . The test proves that the improved algorithm has been effectively reduced in the communication overhead and to some extent improved the accuracy.
