节能有效的无线传感器网络状态信息收集算法

网络状态信息收集协议既要保证信息收集的准确性、实时性,又要保证协议算法的轻量级特性。为解决上述矛盾问题,提出了一种轻量级的、能量有效的、基于无损聚合的层次分簇数据收集机制(QTBDC)。QTBDC首先对网络节点编码并在节点间建立起一个逻辑层次簇结构,然后利用各个子簇状态数据的相似性和编码的连续性,实现了网内无损聚合。该监测机制使得网络状态信息的收集在不丢失数据细节信息的情况下,数据通信量大大减少。经过仿真分析表明,该方法与现有经典数据收集方法相比,实现了节能,延长了网络的生命期。

The protocol of network status information collection guaranteed not only authenticity of the collected infor-mation but also lightweight of the collection algorithm.To solve the contradiction problem,a lightweight,energy efficient,in-network lossless aggregation and hierarchical cluster was proposed based on data collecting mechanism(QTBDC).In QTBDC,all the nodes in WSN were encoded and a logical multi-level cluster was constructed among the nodes.Making use of the similarity of network status data and con...
