【摘要】 自动配置的无线传感器网络(WSNs)作为21世纪最重要的技术之一,在民用和军用方面具有极高的价值,它的发展和广泛应用,将对人们的社会生活和产业变革带来极大的影响和产生巨大的推动。它相对于移动通信网、无线局域网、蓝牙网络、Ad hoc网络等常见的无线网络具有很多新的特点,有很多的研究热点。无线传感器网络由能量有限的节点组成。其应用无线通信的方式来从特定区域采集处理有用的数据,因此如何才能以能量有效的方式来采集、处理数据以保证网络的最大生存时间是WSNs的一个研究重点,即能量问题。同时,近年来,随着技术的发展,以及无线传感器网络自身特点的限制,分层协议设计方法在无线传感器网络中的应用越来越显出其局限性。因此,本文将能量问题与无线传感器网络的另一研究热点通信协议结合,研究能量有效的通信协议,利用跨层设计的思想,提出了一种融合MAC层和路由层的能量有效的通信协议。综合考虑了路由跳数、节点位置、节点能耗对通信协议的影响。仿真结果表明,本文所提出的算法能显著减少网络能耗,提高能源有效性。更多还原

【Abstract】 One of 21st century most important technologies-- the automatic disposition wireless sensor networks (WSNs), has the extremely high value in civil and the military aspect, its development and the widespread application, will bring the enormous impetus to people’s social life and the industrial transformation. It has great many new characteristics to mobile communication network, wireless local area network, Ad Hoc network and such common wireless network .There are many hot spot in the research of WSNs.The wireless sensor networks is composed by the energy limited node. It takes wireless corresponds matter to gather and process useful data from the specific region, therefore how to do gathering and processing by the energy effective way, and guarantee the biggest lifetime of the network is a research key of WSNs, namely energy question. Recently, with the technical development, as well as the wireless sensor network own characteristic limit, the layered protocol design method has the certain limitation in the wireless sensor network application. Thus, this article integrates energy question and communication protocol, mainly uses the crosslayer design to propose a new energy effective communication protocol fuses the MAC layer and the route layer. The proposed protocol considers the influence to route mechanism from the route hop number, node position, energy consumption of each node. The simulation result indicates that the proposed algorithm can remarkably reduce the network energy consumption, enhances the energy efficiency.更多还原
