Abstract
Common transport systems lack the appropriate mechanisms to deal with the problems of mobile computing systems (e.g. temporary inaccessibility, transient network addresses of mobile hosts, along with varying quality of service parameters of physical network connections). Therefore, a need for new adaptive data distribution mechanisms.This paper discusses specific features of GISMO’s (Generic Infrastructure Support for Mobile Objects) infrastructure; in particular, a mobile queuing service — which distributes data in an adaptive manner. In the remainder of this paper we introduce and motivate the need for adaptive data distribution mechanisms, describe our concept, as well as some implementation details and an overview of our first experiences with a prototype implementation.Keywordsadaptationdata distributiondisconnected operationmobile computingmobile transport systemqueuing systems
