Study and Implementation of Wireless Sensor Networks

为了实现高能量效率、低复杂度的无线传感器网络,设计了基于跳数的广播路由(HBBR)协议和随机-媒体接入控制(R-MAC)协议,研究了无线传感器网络节点的低功耗、低成本实现技术,并在此基础之上,研制了无线传感器网络硬件实验系统.计算机仿真和硬件实验表明,所设计的协议能够实现高效、稳定的网络功能;所实现的硬件实验系统,在硬件资源非常有限的条件下,能够实现对移动目标的实时跟踪.

To implement high energy efficiency.and low complexity Wireless Sensor Networks （WSN）, a Hop-Based Broadcast Routing （HBBR） protocol and a Random-Media Access Control （R-MAC） protocol for WSN were proposed. Low power and low cost implementation technologies of WSN nodes were also investigated. Based on these, a WSN testbed was realized. Simulation and hardware trials results show that the proposed protocols are efficient and stable, and with very limited hardware resources, the testbed is able to track moving object in real-time.
