Architecture of Hybrid Mobile Social Networks for Efficient Content Delivery

Content delivery is one of the most important technologies used in Mobile Social Networks (MSNs). Smart devices could enable mobile users to create and use a rich set of services through available resources in the surrounding environment opportunistically. This paper presents the framework of distributed buffer storage aided hybrid Mobile Social Networks (MSN). Based on this, we propose a new scheme with distributed storage for efficient end-to-end content delivery in intermittently connected MSNs. Our proposed hybrid architecture is able to offer fast and reliable delivery services by distributing buffer storage located close to mobile users of the opportunistic MSN. Simulation experiments are conducted to evaluate the performance of the proposed method, which indicate that it is helpful to improve network performance in terms of content delivery ratio, throughput and end-to-end delays.
