智能家居无线自组织网络冲突自适应协议设计
|
摘要
新型的智能家居中众多传感器之间都要将感知的数据传递到收集节点处,系统不但对无线自组织网络的冲突自适应能力提出了新的要求,而且对汇聚节点处的带宽也需要同样提高。本文在分析现有协议的基础上,提出了一种面向智能家居的无线自组织网络冲突自适应协议,并提出了网状网络和传感器网络组成的双汇聚节点的设计。该方案通过调节冲突节点个数和改进收集节点的调度方法,实现了感知数据的高效收集。经过大量实验,结果表明了本文提出的冲突自适应协议设计能够有效的提高智能家居中数据的收集效率,减少延迟。
In the new type of smart home,multiple sensors need to transmit data to the sink node. The data transmission not only puts forward new requirements for the self-organizing network's collision self-adapting capability in the smart home,but also the bandwidth at the sink node also needs to be improved.Based on the analysis of existing protocols,this paper proposes a collision-adaptive protocol for wireless self-organizing networks in smart home,and proposes the design of double convergent node composed of reticular networks and sensor networks. This method realizes efficient collection of sensing data by adjusting the number of collision nodes and improving the scheduling method of sink node. Many experimental results show that the collision adaptive protocol proposed in this paper can effectively improve the efficiency of data collection and reduce the delay in smart home.
