摘要
在位置相关持续查询的结果发布过程中,提出针对每个移动客户单独调整传送窗口大小的增强型自调整周期传送方法,并在此基础上,根据持续查询有效期内查询目标的状态采取更有针对性的动态分类传送方法,以达到在结果发布过程中降低控制消息开销,减少重新传送的可能性的目的。
In the result transmission of location-dependent continuous query,the Enhanced Adaptive Periodic Transmission Approach proposed in this paper can adjust the transmission window size for each mobile host individually.Further more,the objects would be partitioned into two disjoint sets in the query＇s validation period depending on their status：the changing and the none changing,can use specified approaches to transmit in order to decrease the control message overhead and the possibility of retransmission.
