一种移动汇聚节点和静态传感器的双层结构

A Two-layer Architecture of Mobile Sinks and Static Sensors

Natarajan Meghanathan, Gordon Skelton

摘要:

针对大规模无线传感器网络,提出了一种两层移动汇聚和静态传感器网络(MSSSN)结构。顶层是一个移动ad hoc网络的资源丰富的汇聚节点,而底层是一个网络的静态资源受限的传感器节点。MSSSN架构可以用仅使用单个半双工收发器的当前可用的IEEE 802.11设备以较低的成本实现。每个汇聚节点被分配一个特定的区域来监视和收集数据。汇聚节点移动到传感器节点附近(在几跳内)以收集数据。所收集的数据与对等移动接收器交换。因此,MSSSN架构提供了可扩展性,通过让它们在有限的传输范围内工作来延长传感器寿命,并提供传感器节点的隔离区域之间的连接。为了提供容错,多于一个的移动接收器可以从给定区域收集数据,或者移动接收器可以从多于一个的区域收集数据。在后半部分的文件中,我们讨论了几个开放的研究问题,需要解决,而实现MSSSN架构。

英文摘要:

We propose a two-layer mobile sink and static sensor network (MSSSN) architecture for large scale wireless sensor networks. The top layer is a mobile ad hoc network of resource-rich sink nodes while the bottom layer is a network of static resource-constrained sensor nodes. The MSSSN architecture can be implemented at a lower cost with the currently available IEEE 802.11 devices that only use a single halfduplex transceiver. Each sink node is assigned a particular region to monitor and collect data. A sink node moves to the vicinity of the sensor nodes (within a few hops) to collect data. The collected data is exchanged with peer mobile sinks. Thus, the MSSSN architecture provides scalability, extends sensor lifetime by letting them operate with limited transmission range and provides connectivity between isolated regions of sensor nodes. In order to provide fault tolerance, more than one mobile sink could be collecting data from a given region or a mobile sink could collect data from more than one region. In the later half of the paper, we discuss several open research issues that need to be addressed while implementing the MSSSN architecture.
