【摘要】 微机电技术、计算技术、无线通信和网络等技术的快速发展孕育了无线传感器网络。无线传感器网络是由部署在监测区域内大量的廉价微型传感器节点组成，通过无线通信方式形成的一个多跳的自组织的网络系统。它能够协作地实时监测、感知和采集各种环境或监测对象的信息，并对其进行处理，传送给需要这些信息的用户。无线传感器网络是计算机科学技术的一个新的研究领域，具有十分广阔的应用前景，引起了学术界和工业界的高度重视。无线传感器网络中的节点一般采用电池供电，可以使用的电量非常有限，而且传感器节点的通信能力、计算能力和存储能力也非常有限，这对无线传感器网络的硬件和软件设计都提出了挑战性的问题。本文以此为研究背景，总结国内外关于无线传感器网络的研究，提出将Agent技术应用到无线传感器网络中。首先，本文介绍了无线传感器网络和Agent技术的背景、概念、结构和相关理论，作为后面章节的研究基础。其次，根据无线传感器网络的应用要求，对传统的客户机／服务器模式进行分析，它是把数据传回处理中心进行处理，这不适合无线传感器网络这样一个分布式环境。相反，基于移动Agent的分布式计算模式是把处理代码移动到本地节点去处理数据，其所具有的优势和特点非常适合用于无线传感器网络系统。因此提出在无线传感器网络中采用基于移动Agent的计算模式，并进行具体分析和设计。基于无线传感器网络与多Agent系统的相似性，综合考虑移动Agent和多Agent的优势，提出无线传感器网络的多Agent系统模型，并对模型各部分的功能进行描述，通过仿真实验验证所提出理论的可行性和有效性。更多还原

【Abstract】 Wireless Sensor network (WSN) is an emerging area of computer science, driven by advances in Micro Electro Mechanical System (MEMS), nested computation, networks and wireless communication technologies. WSN is constructed by small, low-cost and low-power sensor nodes deployed in large quantity, and it is self-organized network in wireless multi-hop mode. WSN can be used for sensing, collecting and processing information of monitored objects and send information to the user. WSN is a novel technology about acquiring and processing information, which has a wide application future. Both academia and industries are very interested in it.The node of the wireless sensor network often uses batteries to supply electricity, but the electricity energy in the batteries is limited, meanwhile the communication, calculation and storage abilities of the node are limited, which raise challenges to the hardware and software design of the wireless sensor network. This thesis, basing on this background, points out the use of agent technology in wireless sensor network.Firstly, the thesis introduces the background, definition, construct and correlative theories of wireless sensor network and agent technology. Secondly, the thesis analyses the traditional client sever mode according to the usage requirement of the wireless sensor network. The traditional client server mode transfers the data to the processor center to process, which is not suitable for the distribution environment of the wireless sensor. On the contrary., the mobile agent based calculation mode transfers the data to the local node. Its advantages and characteristics are in accord with the requirement of the wireless sensor net work. Therefore, we put forward the use of the mobile agent based calculation mode in the wireless sensor network, and carry out analysis and design accordingly.Finally, considering the similarities of the wireless sensor network and multi-agent system as well as the advantages of mobile agent and multi-agent, the author put forward the designs of the multi- agent system mode of the wireless sensor network, illustrates the function of the component in the mode, and verifies the feasibility and validity of the theory by simulated experiment.更多还原
