摘    要:由于手机中GPS系统定位精度低和室内环境中卫星信号弱,造成移动SNS在室内和近距离环境中社交网络扩展性能差。针对这种情况,提出了基于蓝牙技术的近距离社交网络扩展算法。算法首先在服务器端保存SNS用户手机蓝牙地址与用户的对应信息,然后按照同一区域内"一台蓝牙手机搜索到另一台蓝牙手机"的蔓延模式找到直接相邻的周边用户列表,再在服务器端对周边用户列表按照深度优先算法进行社交网络的深度搜索,找到尽可能多的周边用户并建立社交网络。实验结果表明,移动SNS系统采用该算法比采用现有技术能更加有效、快速地扩展近距离范围内的社交网络。

关 键 词:蓝牙  移动社会化网络服务  近距离

Abstract:Due to the low precision of GPS and weak signal of the indoor environment,the mobile SNS's expansibility indoors and in close distance in social networks is poor.In order to solve this problem,a close-distance extension arithmetic in social networks,which is based on Bluetooth,is put forward.First,this arithmetic stores SNS users' Bluetooth addresses and users' responding information at server end.Then,find adjacent and surrounding users' list according to the extended method--a bluetooth mobile phone to search another Bluetooth mobile phone in the same region.After that, carry out a depth- first search towards the surrounding users' list by means of the depth first arithmetic at server end to search for as many surrounding users as possible and set up social networks.The research result shows that the arithmetic which mobile SNS system adopts turns out more effective than modern technology.What's more,it can expand the close-distance social networks in a more prompt way.
Keywords:bluetooth  mobile social networking services  short-range
