Achieving Optimal Throughput and Near-Optimal Asymptotic Delay Performance in Multi-Channel Wireless Networks with Low Complexity: A Practical Greedy Scheduling Policy
Bo Ji, Gagan R. Gupta, Manu Sharma +2
In this paper, we focus on the scheduling problem in multi-channel wireless networks, e.g., the downlink of a single cell in fourth generation (4G) OFDM-based cellular networks. Ou…
Maximizing System Throughput Using Cooperative Sensing in Multi-Channel Cognitive Radio Networks
Shuang Li, Zizhan Zheng, Eylem Ekici +1
In Cognitive Radio Networks (CRNs), unlicensed users are allowed to access the licensed spectrum when it is not currently being used by primary users (PUs). In this paper, we study…
On the Efficiency-vs-Security Tradeoff in the Smart Grid
Yara Abdallah, Zizhan Zheng, Ness B. Shroff +1
The smart grid is envisioned to significantly enhance the efficiency of energy consumption, by utilizing two-way communication channels between consumers and operators. For example…
Distributed Cross-Layer Optimization in Wireless Networks: A Second-Order Approach
Jia Liu, Cathy H. Xia, Ness B. Shroff +1
Due to the rapidly growing scale and heterogeneity of wireless networks, the design of distributed cross-layer optimization algorithms have received significant interest from the n…
Throughput of Rateless Codes over Broadcast Erasure Channels
Yang Yang, Ness B. Shroff
In this paper, we characterize the throughput of a broadcast network with n receivers using rateless codes with block size K. We assume that the underlying channel is a Markov modu…
Maximizing Social Welfare in Operator-based Cognitive Radio Networks under Spectrum Uncertainty and Sensing Inaccuracy
Shuang Li, Zizhan Zheng, Eylem Ekici +1
In Cognitive Radio Networks (CRNs), secondary users (SUs) are allowed to opportunistically access the unused/under-utilized channels of primary users (PUs). To utilize spectrum res…
On the Generalized Delay-Capacity Tradeoff of Mobile Networks with Lévy Flight Mobility
Yoora Kim, Kyunghan Lee, Ness B. Shroff +2
In the literature, scaling laws for wireless mobile networks have been characterized under various models of node mobility and several assumptions on how communication occurs betwe…
Low-complexity Optimal Scheduling over Correlated Fading Channels with ARQ Feedback
Wenzhuo Ouyang, Atilla Eryilmaz, Ness B. Shroff
We investigate the downlink scheduling problem under Markovian ON/OFF fading channels, where the instantaneous channel state information is not directly accessible, but is revealed…
