In this paper, we discuss using a game-theoretic approach for Network Slicing (in particular RAN Slicing) that enables fully dynamic allocation of spectrum. The algorithm allows radio resources from across the whole spectrum to be allocated to users from different slices, so avoiding the inefficiencies of fixed slices. By using game theory, we can apply constraints on the resources allocated to individual...
In this paper, we use a Spectrum Sharing/allocation algorithm to implement a Cognitive Radio network without spectral awareness. This allows radio resources to be allocated to primary users and to secondary users in such a way that primary system and secondary system are aware of each other. By doing this, sensing of spectrum holes is avoided but the primary users will be protected and will always...
To provide better usage of spectrum, regulators, such as the FCC and Ofcom, have been considering how to share spectrum between operators and also between different types of network. Two important aspects of any mobile service that need to be considered are how to ensure the appropriate level of service to individual users and how to minimize power consumption. This paper addresses the issue by applying...
We propose a spectrum-sharing mechanism for LTE networks taking into account the needs of different network operators and individual QoS requirements. It increases the utilization of spectrum by regarding operators' allocations of spectrum as a shared resource and sets user priorities for accessing this spectrum. In this paper, the example scenario given explains our approach in depth: it has better...
The need to consider the Quality of Service (QoS) requirements of individual users and the business strategies of different operators is gaining widespread acceptance in resource allocation. OFDMA is a suitable technology for delivering very high data rate services because of its inherent ability to remove intra-cell interference. However, cell-edge users will experience high interference from neighboring...
This paper provides a new approach allocating resources between multimedia users in a multi-cell OFDMA system in order to maximize the number of users that can achieve their QoS requirements. It does this by formulating the problem as a non-cooperative game. We propose a distributed algorithm to get the Nash equilibrium (NE) as well as introducing a new performance indicator (the qualified throughput)...
