This paper proposes a dynamic resource allocation scheme based on Nash Bargaining Game (NBG) for the uplink of single-cell multiuser OFDM cellular networks. Although Nash Bargaining Solution (NBS) provides a fair and optimum approach in order to maximize the total rate of the network, there is no simple solution for the case of #36;K#36; users. NBS relates to maximizing the user utilities multiplication...
We present an efficient and fair scheme for allocating resources in the downlink of multiuser OFDMA cellular networks based on Nash Bargaining Solution (NBS). Although NBS provides a fair and optimum approach in order to maximize the total rate of the network, there is no simple solution for the case of K users. The proposed algorithm satisfies the minimum rate requirement of each user first and allocates...
This paper proposes a dynamic subchannel and power allocation scheme based on Nash Bargaining Game for an ad hoc network of Secondary Users (SU) coexisting opportunistically with a Primary base station. Each SU is equipped with an energy detector to sense the Primary User (PU) activity over N OFDM sub-channels. We deploy Nash Bargaining Solution to model the power and subchannel allocation of the...
This paper explores the effect of compressive sensing on channel rate in a massive-MIMO environment. We are interested to know to what extend a channel state information could be compressed and what factors are needed to be considered. For this purpose we assume a base-station with N antennas operating in downlink with K single-antenna users. The sum of rate is calculated and simulated with both original...
In this paper, we propose a collaborative spectrum sensing method based on Stackelberg game in order to improve the sensing performance of cognitive radio users, especially when they are operating under severe channel fading. In this scheme the users with acceptable received SNR are allowed to lead the network sensing process and share their observations with the ones experiencing weak channel conditions...
