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…
Capacity of Compound MIMO Gaussian Channels with Additive Uncertainty
Yin Sun, C. Emre Koksal, Ness B. Shroff
This paper considers reliable communications over a multiple-input multiple-output (MIMO) Gaussian channel, where the channel matrix is within a bounded channel uncertainty region…
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…
An Analytical Approach to the Adoption of Asymmetric Bidirectional Firewalls: Need for Regulation?
M. H. R. Khouzani, Soumya Sen, Ness B. Shroff
Recent incidents of cybersecurity violations have revealed the importance of having firewalls and other intrusion detection systems to monitor traffic entering and leaving access n…
Delay Asymptotics with Retransmissions and Incremental Redundancy Codes over Erasure Channels
Yang Yang, Jian Tan, Ness B. Shroff +1
Recent studies have shown that retransmissions can cause heavy-tailed transmission delays even when packet sizes are light-tailed. Moreover, the impact of heavy-tailed delays persi…
Optimal Distributed Resource Allocation for Decode-and-Forward Relay Networks
Yin Sun, Zhoujia Mao, Xiaofeng Zhong +3
This paper presents a distributed resource allocation algorithm to jointly optimize the power allocation, channel allocation and relay selection for decode-and-forward (DF) relay n…
