Capacity and delay analysis for data gathering with compressive sensing in wireless sensor networks
Zheng, Haifeng; Xiao, Shilin; Wang, Xinbing; Tian, Xiaohua; Guizani, Mohsen (2013 , Article)Compressive sensing (CS) provides a new paradigm for efficient data gathering in wireless sensor networks (WSNs). In this paper, with the assumption that sensor data is sparse we apply the theory of CS to data gathering ... -
Coalitional double auction for spatial spectrum allocation in cognitive radio networks
Sun, Gaofei; Feng, Xinxin; Tian, Xiaohua; Gan, Xiaoying; Xu, Youyun; Wang, Xinbing; Guizani, Mohsen... more authors ... less authors ( IEEE , 2014 , Article)Recently, many dynamic spectrum allocation schemes based on economics are proposed to improve spectrum utilization in cognitive radio networks (CRNs). However, existing mechanisms do not take into account the economic ... -
Cooperative spectrum sharing in cognitive radio networks: A distributed matching approach
Feng, Xinxin; Sun, Gaofei; Gan, Xiaoying; Yang, Feng; Tian, Xiaohua; Wang, Xinbing; Guizani, Mohsen... more authors ... less authors ( Institute of Electrical and Electronics Engineers Inc. , 2014 , Article)We study the relay-based communication schemes for cooperative spectrum sharing among multiple primary users (PUs) and multiple secondary users (SUs) with incomplete information. Inspired by the matching theory, we model ...
