【摘要】 无线传感器网络是一种新兴的技术,与传统的网络相比最突出的特点就是超大规模,无人值守,应用环境变化频繁。解决能量受限问题,适应变化频繁的拓扑结构是目前无线传感器网络面临的最大挑战。针对这一特点,本文以优化网络资源和延长网络寿命为目标,归纳了无线传感器网络部署、任务分配、信息处理和中间件定位中的优化问题,并分别对这些具体问题进行了探讨,对一些可能的研究方向进行了简要的阐述,为以后的研究奠定了基础。更多还原

【Abstract】 As a new domain of networks, wireless sensor networks (WSN) differ from traditional networks in that the networks have a large number of unattended sensor nodes working in dynamic circumstance. The prominent challenges in WSN are energy constraint and dynamic circumstance. According to this, resource optimization for longer lifetime is the object in WSN design. The optimization issue in WSN deployment, task allocation, information processing, and localization is summarized in the paper. Some details are discussed respectively. Furthermore, the future work is presented.更多还原
