摘要：

数据收集传感器网络的漏斗效应是制约网络性能的瓶颈。针对静态数据收集传感器网络，依据空间复用技术和减少跳步数原则，构建多模层次网络，实现不同层次数据包分流，解决sink及其邻近几跳节点的瓶颈问题，达到缓解拥塞、降低传输时延的目的。实验结果表明，该方法在降低节点间通信干扰的同时，能有效减轻传感器节点的数据转发负担，提升网络性能。

Abstract:

Network performance is restricted by funnel effect of the data collection sensor networks. With the static data collection sensor networks in mind, based on spatial multiplexing and reduceing the number of hop-step principle, this paper designs construction of multi-mode-level network to achieve different levels of data packets streaming, in order to solute the sink and its few neighboring nodes bottleneck problem effectively, reaches the purpose of easing congestion and reducing transmission delay. Experimental results show that the method can reduce the communication jamming between nodes, lighten data transmitting burden of the nodes effectively, and obtains the network performance.

Key words: data collection sensor network, funnel effect, multi-mode-level network, spatial reuse
