基于位置信息的路由协议被广泛认为是一种可扩展的移动自组网路由解决方案.大多数此类协议假定可通过位置服务协议获取结点的位置信息.研究人员现已提出多种位置服务协议.但是,它们在大规模网络环境中的可扩展性不好,或者在高动态网络环境中可靠性不高.本文提出了一种适用于大规模移动自组网的面向群组移动性的可扩展及可靠的位置服务协议.模拟结果表明此协议比SLURP协议更适合于具有群组移动性的大规模移动自组网. 

Location-based routing is w idely considered as a potentially scalable routing solution in mobile ad hoc netw orks． Location-based routing protocols assume that a location service is available to provide location information of each node in the netw ork．M any location service protocols have been proposed in the literature．How ever，either they do not scale w ell in largescale netw ork environment or they are not so reliable if the netw ork is highly dynamic．T his paper proposed a scalable and reliable location service protocol for group mobility in large-scale mobile ad hoc netw orks．Simulation results show that the proposed protocol outperforms the SLURP protocol in the case of group mobility in large-scale mobile ad hoc netw orks．
