【摘要】 近十年来,国内外学者掀起了一股针对无线传感器网络的研究热潮。研究指出无线传感网具有广阔的应用前景,但这些应用都需要建立在数据可靠传输的基础之上,因此,基于具体应用的传感网路由协议设计是重点研究方向之一。本文首先概述了静态传感网、移动传感网以及车载移动传感网三个领域的典型路由协议算法,指出车载移动传感网是目前一个新的研究热点;然后提出了一种基于分组转发状况的车载自组织网络路由协议算法,旨在根据分组在网络中的实际转发状况来选择最优路径,该算法直接以分组的转发延迟及转发成功率为表征因素来选择最优转发路径,NS2仿真结果显示,此协议可实现充分利用当前路况信息转发分组,在平均延迟时间、分组丢失率、转发成功率等方面优于GPSR、GPSR-L协议算法;最后在对上述理论研究的基础上,分析了ZigBee协议栈采用的路由协议,并对其进行了修改,然后设计了一个基于ZigBee传感网的智能照明控制系统,测试结果表明该系统可以稳定工作于全自动状态,根据室内场景变化自动调整照明模式。更多还原

【Abstract】 In recent years, Wireless Sensor Network (WSN) has emerged as a promising field of research, leading to a great application potential. But all of these applications have to rely on reliable data transmission, so the routing protocol for WSN based on specific applications has been a hot research field. In this thesis, an overview of the routing algorithm for static sensor networks, mobile sensor networks, and vehicular mobile sensor network is given first, and the author proposes a packet-delivery condition aware routing (PCAR) algorithm for vehicular mobile sensor network with the purpose to use direct metrics to build a high quality route. It uses packet delivery ratio and average packet delay time as the metrics for calculating optimal route. Simulations based on NS2 platform are also conducted, and the results demonstrate that PCAR scheme outperforms GPSR and GPSR-L, in terms of average packet delay time, packet loss ratio, and packet delivery ratio. Finally, based on the previous theoretical research, the author analyzes and modifies the routing protocol in ZigBee protocol stack, and then presents an intelligent indoor light control system based on ZigBee sensor network, the experiment shows that the system can work automatically, adjusting lighting mode according to indoor scene changes.更多还原
