Prospects and Challenges of Context Aware Multimedia Content Delivery in Cooperative Satellite and Terrestrial Networks

Our article focuses on context-aware content delivery through cooperative satellite networks and terrestrial wireless communication networks because of their potential to deliver multimedia content and services to users anywhere on the planet. However, due to the inherently different technologies used by satellite networks and terrestrial mobile networks, there may be a significant impact on users’ perceived service quality and resource utilization. For example, in order to deliver context-aware TV programs to a user through a satellite, the delivery method is typically unicast, which is obviously an expensive operation because satellites are intrinsically useful for broadcasting or multicasting services to many users. On the other hand, usually terrestrial mobile networks are better capable of delivering unicast-based context-aware content delivery. Furthermore, traditional cooperativesatellite and terrestrial networks share a fixed bandwidth allocation method. However, due to non-uniform geographical distribution of users, dissimilarity of required contents depending on specific regions and or users, and so forth, the fixed bandwidth allocation and the conventional way of utilizing these networks satellite networks are used during post-disaster recovery operations, while terrestrial networks are used in normal times are inefficient. In order to address these challenges, in this article, we propose a novel method to dynamically assign bandwidth in the satellite terrestrial frequency sharing system to deliver context-aware contents to many users. The remainder of the article is organized asfollows. First, we survey some relevant research works. Key challenges pertaining to contextaware information delivery are then elucidated. Next, we describe our considered network model of satellite and terrestrial frequency sharing system, and also illustrate the problem of traditional fixed bandwidth allocation in cooperative satellite and terrestrial networks. Then our proposal is presented, followed by its performance evaluation. Finally, the article is concluded. content delivery to users. Since our work aims to address the challenges pertaining to context- aware content delivery across such networks, and envisions an adequate proposal todeal with the challenges, it is also important to have a brief.
