近年来，随着微机电系统(Micro-Electro-Mechanism System，简称MEMS )、无线通
信、信息网络与数字集成电路等技术的迅速发展，低成本、低功耗以及多功能的传感器
得到广泛应用。这些微型的传感器节点集成了数据感知、处理与传输等功能，通过节点间的相互协作，以无线多跳方式组成一个自组织网络，即无线传感器网络(Wireless Sensor Networks，简称WSN ) 。WSN最主要的任务就是监测物理环境，并将节点感知的信息高效、准确地转发到基站(C Sink )。这种数据交互模式将真实的物理世界和逻辑的信息世界融合在一起，深刻地改变了人与自然的交互方式。无线传感器网络广泛地应用于以下领域。
Wireless sensor networks(WSN ) have exoteric environment, dynamic topology structure and limited resource node, which enables its security issue to be the research hotspot and difficulty point of this field. This thesis is focus on structure and reliable data transmit of WSN, and the framework is as following. (2017-07-10, C/C++, 27629KB, 下载13次)
