This paper reports on a study conducted to ascertain the requirement for developing Virtual Learning Environments (VLEs) and how these needs are met using fitness function for modelling the solution to meet the requirements and demands of such as system. The systems used for this study was University of East London blackboard Learning System called UEL Plus. We realized that UEL Plus has multiple features to support teaching and learning. UEL Plus provides an improved communication, access
to resources and advanced assessment capabilities. Our study focused fundamentally on the UEL Plus which part of VLE. The rest of the paper is organized as follows: Section 2 will describe end user
categories and section 3 will highlight the mobile agents as a solution. Section 4 will introduce mobile agent fitness function and Section 5 will discusses the mobility in VLE in section 6 draws conclusion
