“…However, the literature [21] proposes an architecture that integrates satellites with terrestrial information center networks (ICNs). In [22], a network model for satelliteassisted emergency communication based on the ground information center network architecture is proposed which greatly reduces the end-to-end delay of emergency data.…”

The incorporation of the cognitive radio (CR) technology as a spectrum management tool in satellite communication has attracted considerable research attention because the CR allows the coexistence of the primary and secondary networks using the same resources. In this paper, satellites and their users are considered as a primary network, and the terrestrial base stations (BSs) and their users are considered as a secondary network. Besides, it is considered that terrestrial users cause interference to satellite users due to technical and environmental constraints. This interference reduces satellite users' satisfaction with downloads rate. In such a cognitive satellite network environment, content placement may also cause a decrease in user satisfaction. The successful download probability (SDP) is analyzed in this work based on different terrestrial user density. To utilize the satellite cache resources effectively, we propose two transmission strategies based on the terrestrial user density, namely, the multi-point cooperative transmission strategy (CT) and the parallel transmission strategy (PT). In addition, based on the cache service probability we determine the ratio of content distribution most popular content (MPC) and general popular content (GPC) and optimize the content placement process using the utility function in CT mode. Through computer simulation, we give numerical results of our method. The obtained numerical results show that the proposed strategies are effective in content placement.

“…Therefore, the introduction of ICN in satellite networks can not only make up for the shortcomings of existing satellite networks, but also combine with the current evolution trend of terrestrial networks to give full play to the performance of satellite networks. At present, based on the ICN idea, many scholars have carried out many researches and experiments on key technologies such as satellite network architecture, routing and forwarding, and buffering [6,7,8], demonstrating the feasibility of ICN in satellite network from many aspects. Below, we will introduce the ICN working mechanism and the technical advantages in satellite networks in the second section.…”

ICN was introduced into satellite networks to meet the growing demand for content acquisition. The caching mechanism is one of the most critical parts that profoundly affects the performance of the network. Based on the application background of satellite networks, the working mechanism of ICN and its technical advantages in introducing satellite networks are elaborated. The application status of ICN cache in satellite networks is analyzed to explore the applicability of existing caching mechanism in satellite networks, and the development and challenges of ICN caching mechanism in satellite network are analyzed.

“…Furthermore, numbers of solutions and strategies from other areas in communication networks can inspire the scholars to solve the caching difficulties [24][25][26][27][28][29][30]. In this paper, we focus on the IP-based caching architecture which is a research hot point in recent years [31][32][33][34][35]. In [31], the authors proposed an in-network caching solution in IP-based networks by inserting a content identifier into a new-coming IPv6 extension header, wherein the proposed architecture is called caching-based IP networks.…”

Content caching is a promising approach to enhancing bandwidth utilization and minimizing delivery delay for new-generation Internet applications. The design of content caching is based on the principles that popular contents are cached at appropriate network edges in order to reduce transmission delay and avoid backhaul bottleneck. In this paper, we propose a cooperative caching replacement and efficiency optimization scheme for IP-based wireless networks. Wireless edges are designed to establish a one-hop scope of caching information table for caching replacement in cases when there is not enough cache resource available within its own space. During the course, after receiving the caching request, every caching node should determine the weight of the required contents and provide a response according to the availability of its own caching space. Furthermore, to increase the caching efficiency from a practical perspective, we introduce the concept of quality of user experience (QoE) and try to properly allocate the cache resource of the whole networks to better satisfy user demands. Different caching allocation strategies are devised to be adopted to enhance user QoE in various circumstances. Numerical results are further provided to justify the performance improvement of our proposal from various aspects.
