Abstract

En 中文
This article examines when a mobile system should view a resource as portable (and hence carried by its user), and when it can be viewed as pervasive (and hence easily found whenever and wherever needed). It shows that the anticipated worst case scenario while mobile is the critical determinant. If the resource is easily and reliably available at all visited locations, then it can be treated as a pervasive resource. If there is reasonable doubt about its availability or attributes at even one visited location, then it has to be treated as portable. Using this resource-centric viewpoint, this article highlights the unique role of the cloud in mobile computing, as well as its limitations. It discusses how some legacy systems can be rearchitected using modern technology, and how emerging real-time mobile AI systems will have to straddle the carry versusfind divide.
