Contextual - knowledge management in peer to peer computing

Abstract

In the pervasive computing environment consisting of peers (clients/servers or agents) contextual knowledge is an important feature to be embedded. Here, the traditional transaction model needs to be replaced by a model called a "Workflow model" between several peers that interact, compete and cooperate. Eiffel, iContract tool of Java and UML are powerful languages to implement the Peer-Peer-Pervasive-Program. They provide for program constructs essential to deal with the uncertain nature of connectivity of pervasive devices and networks, and the trial-error (subjunctive) nature of the processes and the programs used in E-commerce and robotics.
