【摘要】 基于低能量自适应聚类层次(Low-Energy Adaptive Clustering Hierachy,LEACH)的通信协议,提出了适用于无线传感器网络的Multi-frame LEACH多帧通信机制。通过定量分析传感器节点的通信能量消耗,建立了聚类首领剩余能量与通信流量的关系模型。MF-LEACH通信机制加入了聚类状态检查阶段,阐述了可用的规则;在数据传输阶段,应用预测策略动态决定传输数据帧的数量。初步的研究表明:Multi-frame LEACH能更有效节省能量,提高通信效率。更多还原

【Abstract】 Multi-frame LEACH communication mechanism was proposed for wireless sensor networks, based on LEACH communication protocol. Through analyzing communication energy dissipation of wireless sensor nodes quantitatively, the relational model of cluster heads’ residual energy and communication traffic was established. Cluster state check-up phase(CSCP) was added into multi-frame LEACH, and practicable rules for CSCP were explained. In data transmission phase, prediction strategy dynamically determined the amount of frames to transimit. Preliminary research shows that multi-frame LEACH can save more energy and improve communication efficiency.更多还原
