In this paper, we study joint source and relay precoding strategy selection for multiple-input multiple-output (MIMO) relay networks from a game theoretic approach. We appropriately formulate it as a potential game in which the rate is the common utility and also the potential function. This game is shown to possess at least one pure strategy Nash equilibrium (NE) and the optimal strategy profile...
A main target of the next generation wireless networks is to integrate multiple wireless access technologies to provide seamless mobility to mobile users with high-speed wireless connectivity. Network selection is one of the most significant challenges for load balancing to avoid network congestion and performance degradation because of the heterogeneous wireless access environment in next-generation...
In cognitive radio networks, cooperation between users can improve each network's performance. In this paper, a cognitive relay network is considered where the secondary users (users in Ad-Hoc network) are involved as cooperative relays in primary users' communication. The primary user owns a given bandwidth and can decide to lease it for a fraction of time to secondary users in exchange for appropriate...
