An Efficient Content Dissemination Approach for Mobile E-Learning

Abstract

Abstract. With the rapid development of Device-to-Device (D2D) wireless communication technologies and the wide applications of human-carried smart mobile devices such as smart phones and tablets, content sharing attracts numerous attentions in mobile E-learning environments. Due to the high mobility of humans and the resource-limited smart mobile devices, the design of efficient content sharing schemes faces great challenges. This paper presents a novel data dissemination approach for efficient content sharing in mobile e-learning environments. In the proposed approach, a policy of random splitting and broadcasting of contents is applied to decrease the number of re-transmissions. The simulation results prove its efficiency and higher delivery ratio compared with traditional approaches.
