| 中文摘要 | 无线传感器网络的随机部署、自组织、环境适应等特点使其在军事、环境、医疗、工业和其他领域有广阔的应用前景和很高的应用价值。工业无线传感器网络是无线传感器网络在工业中的具体应用，它在保留了无线传感器网络基本特性的同时，对其进行改良使之更适应复杂多变的工业现场环境，具有抗干扰能力强、能耗低、通信实时性好等技术特征。目前，在工业无线传感器网络中对于QoS 保障机制的需求越来越迫切，而其中，有关网络层的QoS保障研究（即QoS路由算法或协议研究）受到的关注最多，相关研究也最深入广泛。 目前，已经提出的基于QoS的路由协议在维护报文传输可靠性和网络能量消耗方面存在问题。针对工业无线传感器网络的特点，以及其对QoS最主要的两个要求—可靠性和节能性，提出了一种高可靠性低能耗的多路径路由协议(REMR），该协议以地址为中心，利用多路径路由方式、端到端可靠传输机制和负载均衡，实现数据的可靠传输以及能源的有效利用。 首先，对可靠性和节能性的QoS机制进行了分析，结合这两种机制提出了一种基于遗传算法的QoS路由算法，并进行了仿真实现。在可靠性方面，分析了端到端可靠性相对于点到点可靠性维护机制的优点，以及其对于工业无线传感器网络的适用性，实现了端到端可靠传输机制。在节能性方面，从负载均衡和路由信息捎带技术两方面进行了分析与实现。 REMR路由协议主要分为路由发现和路由维护两部分主要内容。在路由发现部分，提出了邻居质量估计算法，通过图路由与代理路由相结合的方式，进行邻居发现与路由建立，实验结果表明REMR路由协议能够在少量增加网络资源开销的前提下，有效地降低报文丢失率和网络能耗，延长网络生存时间。 在路由维护部分，提出了一种基于双向多路径的快速路由维护机制，通过网关和节点双向检测，主辅路径相互维护的方式，提升了路由维护速度，保证了路径检测的可靠性。实验结果表明双向多路径快速路由维护机制能够在少量增加网络能耗的前提下，有效地改善路由维护时间和路由维护准确率等网络性能。 |

| 英文摘要 | For wireless sensor networks has features of random deployment, self-organization, environmental adaptation, etc, it has potential value for applications in military, environmental, medical, industrial and other areas. Industrial wireless sensor networks is the specific application of wireless sensor networks in industry, and it maintains the basic features of wireless sensor networks, as well as improves it to adapt the industrial enviorment, it has its own features of anti-interference ability, low energy consumption, real-time communication, etc. Nowadays, there are increasing needs of QoS guarantee mechanism for industrial wireless sensor networks. Among these needs, QoS guarantee mechanism of the network layer (ie, QoS routing algorithm or protocol) is the most frequent, there are also many researches on it as well. At present, the already proposed QoS routing protocol has problems in the maintenance of the network reliability and energy consumption. According to the features of industrial wireless sensor networks, and its main requirements of QoS guarantee mechanism — reliability and energy efficiency, this paper proposes a high-Reliability low-Enenrgy-consumption Multipath Routing protocol(REMR). The Protocol bases on the address, and the packets are transmitted reliably with mutipath routing and end-to-end reliable transmition mechanism, the energy of the network can also be saved by load balancing. First, analysis the reliability and energy efficiency mechanism, and proposes a QoS routing algorithm based on genetic algorithm. In reliability, analysis the advantages and applicability to the industrial wireless sensor networks of end-to-end reliability mechanism relative to node-to-node reliability mechanism, accomplishes the end-to-end reliability mechanism as well. In energy efficiency, analysis and accomplishes it in load balancing and piggyback routing information technology. REMR routing protocol consists of two main elements, which are route discovery and routing maintenance. In route discovery, proposes the algorithm of neighborhood quality estimation, and combines the figure routing and proxy routing to accomplish the neighborhood discovery and route setup. Experiment results show that REMR routing protocol reduces the packets lost rate and the enenrgy consumption of the network, as well as extends the lifetime of the network, and only causes little resource overhead. In routing maintenance, a high-speed route maintenance mechanism based on two-way multi-path algorithm is presented. Through two-way detection, as well as reciprocal maintenance, the route maintenance mechanism increases the speed of route maintenance and assures the reliability of route detection. Experiment results show that high-speed route maintenance mechanism reduces the period, as well as increases the accuracy of route maintenance, and only causes little energy consumption. |
