摘要
物联网中节点能耗一直是限制物联网应用种类和规模的重要因素,数据汇聚是减少网络中数据传输主要节点能耗的一种重要方法。本文利用一定范围内的同类节点读数相近的特点,设计了一种基于Zig Bee节点类型的簇内数据汇聚方案。理论分析与模拟实验证明,该方案通过合理的参数设计可以有效减少簇内节点数据通信量。
The energy consumption of nodes is an important factor to restrict the type and size of the applications in WSN,Data aggregation is an important way to reduce the energy consumption for the main nodes transmission the data in the network. In this paper,using the feature of similar nodes with similar readings within a certain range,designed a data aggregation scheme based on the Zig Bee node type. It is proved by theoretic analysis and simulation experiment that this scheme can effectively reduce the cluster＇s nodes data communication through the reasonable parameters design.
