现有无线定位研究大多侧重固定的网络结构，使用GPS、WiFi等单一的定位技术，缺乏灵活性。GPS定位技术容易受到建筑物遮挡造成信号严重衰减，导致移动设备无法通过G PS卫星直接获取当前的实际地理位置信息。而移动自组织网络具有拓扑结构动态性、良好的灵活性和扩展性等特点，支持数据共享应用，受到学术界和工业界的广泛关注。论文结合移动自组织网络和蓝牙技术，设计和开发了基于移动设备G PS信息共享的定位系统。测试表明，该系统可以利用手机设备组建移动自组织网络，实现移动设备的灵活定位需求，具有较好的应用前景。

Most of the existing research on the wireless location focuses on fixed network structure ,using GPS ,WiFi and other single positioning technology ,and lacks of flexibility .GPS positioning technology is vulnerable to buildings bloc‐king ,resulting in the signal attenuation severely ,and making a mobile device impossible to directly get the current actual lo‐cation information via GPS satellites .The mobile ad‐hoc network has the characteristics of dynamic topology ,good flexibility and scalability features to support data sharing applications ,and has been attracted widespread attention in academia and in‐dustry .In this paper ,a GPS positioning information sharing system based on a combination of mobile ad hoc network and blue‐tooth technology is designed and developed .The experiment shows that the system can use mobile devices to form a mo‐bile ad‐hoc network ,and achieves a flexible positioning capability with good prospects .
