In this paper, we investigate the resource allocation for the video streaming service in the cognitive radio network (CRN) based on orthogonal frequency division multiple access (OFDMA). Considering the channel estimation error between secondary transmitters (STx) and primary receivers (PRx), we address the probabilistic interference constraint model. With imperfect CSI between STx and secondary receivers...
Spectrum sensing and spectrum sharing are two fundamental issues in a cognitive radio network (CRN). The spectrum sensing data falsification (SSDF) attack imposes bad effects on both spectrum sensing and spectrum sharing. To deal with SSDF attacks and to incentivize secondary users (SUs) to behave well, a joint spectrum sensing and resource allocation (JSSRA) scheme in a CRN is proposed in this paper...
This paper investigates the allocation of anchorage resource in upstream harbour district of Yangtze River from the perspective of price leverage. Anchorage is often referred to the area for the vessel to anchor before loading/unloading operation at the dock. As a public resource, anchorage has a properties of "non-exclusive" and "non-compete". Traditional management methods of...
In this paper, we investigate the video stream distributed transmission problem for the emergency communication over heterogeneous wireless networks. The key issue of the transmission problem is how to guarantee the quality of service, when the video stream is transmitted by multiple wireless access networks. According to observed available bit rate (ABR) and round trip time (RTT) over each access...
How to allocate rate to users with multiple services efficiently and fairly is an important issue in the wireless network. To ensure the quality of service required by multiple services of a user, efficient resource management becomes paramount. On the other hand, the fairness between users is also necessary. In this paper, we propose a bandwidth allocation scheme named as Efficiency and Inter-user...
Bandwidth allocation for multi-user sharing heterogeneous wireless access networks is one of the most important problems in the next generation wireless networks. In this paper, we propose a bandwidth allocation scheme named as Efficient and Fair Rate Allocation (EFRA), which is formulated as a convex optimization problem maximizing the user's utility as well as determining to split the total rate...
Allocating bandwidth to multiple users sharing multiple heterogeneous access networks is an important issue in the next generation wireless networks. In this paper, we propose a bandwidth allocation scheme named as Efficient and Fair Allocation in Rate (EFAR), which is formulated as a convex optimization problem that maximizes the utility of each user and determines how to split the total rate among...
