“…A large body of works on RA in satellite systems exists in the literature. Brückner et al propose a dependency-aware reservation approach for mobile satellite communications in [27]. This reservation mechanism utilizes power to signal path dependencies at the resource management phase of the satellite network.…”

“…This reservation mechanism utilizes power to signal path dependencies at the resource management phase of the satellite network. In our work, we mainly focus on distinct mode management and cognitive operation management in our complex satellite integrated D2D architecture rather than link formation as in [27]. Besides, we perform a more rigorous EE analysis for the network.…”

Next-generation wireless systems are expected to provide bandwidth-hungry services in a cost-efficient and ubiquitous manner. D2D communications, spectrum sharing and heterogeneous network architectures (HetNets) are touted as crucial enablers to attain these goals. Moreover, the shifting characteristics of network traffic towards content consumption necessitate content-centric architectures and protocols. In this work, we propose a comprehensive analytical model for a content-oriented heterogeneous wireless network with cognitive capability. We model our HetNet architecture with a Continuous Time Markov Chain (CTMC) and characterize the trade-off between energy efficiency and system goodput. We elaborate on novel elements in our model, namely the integration of universal source concept (modeling the content retrieval operation from external networks), caching and overlaying in D2D mode. Besides, our investigation on network mode selection provides further insight on how resource allocation and performance are intertwined.

“…Apart from the power saving, it also increases network user rates. Brückner et al propose a dependency aware reservation approach for mobile satellite communications in [13]. In [14], they propose medium access control (MAC) over cognitive radio networks with two sensing algorithms where one senses randomly while the other is negotiation-based.…”

Content-oriented operation with D2D communications and spectrum sharing in the form of cognitive communications are expected to be enablers for cost-efficient nextgeneration wireless systems with bandwidth-hungry services. To this end, caching is an important building block of these systems. In this work, we model such a heterogeneous network and model a popularity-aware caching algorithm where we try to keep more popular contents in caches of system units with a higher probability compared to less popular contents. Moreover, for improving the usage of the channel capacity, overlaying for device-to-device (D2D) transmissions (unless these transmission interfere with each other) is enabled. We model our system with an analytical continuous time Markov chain (CTMC). We have a heterogeneous network architecture consisting of a LEO satellite, base station (BS) and a set of devices within the boundary of BS coverage that can get service from the satellite, from the BS or in D2D mode. Our devices operate in primary mode when they get service from the satellite but in secondary mode when they get service from the BS or some device in D2D mode over the terrestrial link. We evaluate our system for energy efficiency (EE) and goodput metrics. We looked how popularity-aware caching, integration of universal source concept and overlaying in D2D mode affect the network performance. Besides, we investigate how resource allocation (RA) and performance metrics are tangled.
