普适环境中,定位计算是上下文察觉计算的重要内容。本文提出分布式定位计算的思想,该思想摆脱了以往传统定位中先确定用户坐标再判断其所处区域的繁琐模式,将对用户所处区域的计算分散至底层的感知设备中,减轻了计算设备的计算负担,提高了上下文感知系统的效率,并通过实现该定位设计验证了分布式定位设计的可行性。
In the pervasive computing environment, location-aware computing is a very important part of context-aware computing. This paper provides an design of the distributed location-aware computing which breaks away from the traditional and fussy location-aware mode that getting the coordinate of the user before estimating which area the located target stays in , disperses the location - aware computing to the bottom aware equipments, so that the computing burden of computing equipments can be reduced. Realization of this design shows the feasibility.
