摘要
具备一种底层基础设施来指示网络运行时的失效节点、资源消耗以及系统综合性能,对于传感器网络这样的分布式系统相当重要.研究了用于系统状态监测的数据分发与收集网络协议,提出了基于最大连通度的分簇模型,并通过仿真对其有效性进行了验证,在该模型基础上设计与实现了用于系统状态监测的层次型数据分发与收集网络协议,仿真证明该协议与现有数据分发与收集协议相比具有更好的可扩展性与能量有效性.
Health monitoring is an essential part of wireless sensor networks.Being focus on studying data collection and dissemination protocols,a clustering model based on maximum connectivity is proposed and validated effectively by simulation,on the basis of which hierarchical data collection and dissemination network protocols are implemented.Moreover,the simulation results show that the new protocols are better than existing ones on the energy-efficiency and scalability.
