Virtual learning system: A conceptual framework of network optimization

The demand for network communications is increasing every year, but the available resources are not increasing at the same rate. Bandwidth and network infrastructures are major issues in network related problems in remote areas for various applications. The current study uses Genetic Algorithm (GA) based optimization method to allocate the bandwidth related issues. In addition, it also considers the identification of optimal server location with minimal cost. In this regard, Geographical Information System (GIS) is used to identify the spatial location of network components (server setup) optimal location. The proposed methodology is demonstrated with a case study of National Programme on Technology Enhanced Learning (NPTEL) developed by Ministry of Human Resources Department (MHRD), Government of India, where the network optimization is of much importance. © 2012 Springer India Pvt.
