Task delegation model assigned to mobile computing

Abstract

One of the main reasons for using scripts in mobile computing is to be able to delegate tasks from a portable terminal to a workstation with more resources. Initially, it has been considered to associate each user with a unique dedicated representation agent on the wired network. Tasks designed as a script are sent to this agent to take advantage of network opportunities. This paper describes the task role and delegation even if the task is not completely and precisely defined before the sending phase. In this latter case, missing information on the workstation, are imported from distant server(s) through remote script import protocols. A cache architecture is presented to make this operation as efficient as possible. In addition, security features are also discussed according to the main characteristics of the different kinds of scripts, namely personalized, certified, protected, etc., which are envisaged.
