The proposed system is used for providing a collaborative learning among local schools of rural area in Nepal. The stable operation of the system is realized by the redundant robustness in three different levels: network arrangement, energy management, and replicative database. In this paper, we present an overall design of the system and its use case. Then, methods adopted for achieving the redundancy in each level are described.}, pages = {496--501}, publisher = {IEEE}, title = {Implementation of Collaborative E-learning System for Unstable Environment}, year = {2017}, yomi = {サトウ, カズヒコ} }
