To tackle asymmetric information, agent ineffectiveness existing in the service outsourcing industry, the paper takes secondary subcontracting services inside the clusters into consideration, which discusses the effectiveness of incentives in principal-agent model of outsourcing. The game models are put forward. According to the results,the constraints range of incentives that the outsourcing contract-issuing...
The fixed channelization structure used by IEEE 802.11-based WLANs constrains the total capacity and leads to unfairness. The concept of variable-width channels is recently proposed to overcome these drawbacks. To investigate the problem of the non-overlapping variable-width channel allocation for selfish access points (APs) in a WLAN, we model it as a non- cooperative game, we aim to investigate...
In this paper, we consider the channel allocation for selfish secondary user (SU) in cognitive radio networks. In general, there are two allocation approaches for our scenario. The user-centric allocation approach aims to maximize the revenues of individual SUs and the system-centric allocation approach attempts to maximize the system revenue. In this paper, we focus on the joint user-centric and...
In cognitive radio networks, secondary users (SUs) opportunistically exploit the spectrum unutilized by primary users (PUs). In this paper, we study the secondary communication where secondary transmitters and receivers have different available spectrum. Considering the spectrum diversity and the space distance between different PUs, we introduce cognitive relay node into the secondary communication...
Cognitive radio (CR) is a revolutionary technology of wireless mobile communication. Smart users can use the CR technology to sense the surrounding environment, search for available spectrum resources and access spectrum dynamically. Therefore, the efficiency of spectrum can be improved and the capacity of wireless communication system will be increased. The cognitive radio technology is introduced...
