Coupling cyber and physical systems gives rise to numerous engineering challenges and opportunities. An important challenge is the contagion of failure from one system to another, which can lead to large-scale cascading failures. However, the self-healing ability emerges as a valuable opportunity where the overlaying cyber network can cure failures in the underlying physical network. To capture bo... View full abstract»

• ### Sequential Detection for Cognitive Radio With Multiple Primary Transmit Power Levels

Publication Year: 2017, Page(s):2769 - 2780
| | PDF (1077 KB) | HTML

In this paper, we consider the sequential detection problem in a new cognitive radio scenario when the primary user (PU) works with more than one transmit power level. Different from most existing literature where PU is assumed to operate with a constant transmit power only, this new consideration well matches the practical standards, e.g., IEEE 802.11 Series, LTE, LTE-A, and so on, as well as the...

We propose a novel random access (RA) scheme with the quality of service (QoS) guarantees for machine-to-machine (M2M) communications. We consider a slotted uncoordinated data transmission period during which machine type communication (MTC) devices transmit over the same radio channel. Based on the latency requirements, MTC devices are divided into groups of different sizes, and the transmission ... View full abstract»

Publication Year: 2017, Page(s):2931 - 2942
| | PDF (2399 KB) | HTML

A scalable framework is developed to allocate radio resources across a large number of densely deployed small cells with given traffic statistics on a slow timescale. Joint user association and spectrum allocation is first formulated as a convex optimization problem by dividing the spectrum among all possible transmission patterns of active access points (APs). To improve scalability with the numb... View full abstract»

• ### Resolution-Based Content Discovery in Network of Caches: Is the Control Traffic an Issue?

Publication Year: 2017, Page(s):2943 - 2955
| | PDF (1747 KB) | HTML

As networking attempts to cleanly separate the control plane and forwarding plane abstractions, it also defines a clear interface between these two layers. An underlying network state is represented as a view to act upon in the control plane. We are interested in studying some fundamental properties of this interface, both in a general framework, and in the specific case of content routing. We try... View full abstract»

| | PDF (1727 KB) | HTML

Caching and multicasting at base stations are two promising approaches to support massive content delivery over wireless networks. However, existing scheduling designs do not fully exploit the advantages of the two approaches. In this paper, we consider the optimal dynamic multicast scheduling to jointly minimize the average delay, power, and fetching costs for cache-enabled content-centric wirele... View full abstract»

• ### Interference Resilient Duty Cycling for Sensor Networks Under Co-Existing Environments

Publication Year: 2017, Page(s):2971 - 2984
| | PDF (3171 KB) | HTML

To save energy, wireless sensor networks often run in a low-duty-cycle mode, where the radios of sensor nodes are scheduled between ON and OFF states. For nodes to communicate with each other, low power listening (LPL) and low power probing (LPP) are two types of rendezvous mechanisms. Nodes with LPL or LPP rely on signal strength or probe packets to detect potential transmissions, and then keep t... View full abstract»

• ### Multiple Target Counting and Localization Using Variational Bayesian EM Algorithm in Wireless Sensor Networks

Publication Year: 2017, Page(s):2985 - 2998
| | PDF (1460 KB) | HTML

Localization technologies play an increasingly important role in pervasive applications of wireless sensor networks. Since the number of targets is usually limited, localization benefits from compressed sensing (CS): measurements number can be greatly reduced. Despite many CS-based localization schemes, existing solutions implicitly assume that all targets fall on a fixed grid exactly. When the as... View full abstract»

• ### Analog Transmission of Correlated Sources Over Fading SIMO Multiple Access Channels

Publication Year: 2017, Page(s):2999 - 3011
| | PDF (1298 KB) | HTML

Joint source-channel coding for discrete-time analog sources is an appealing transmission approach because of its extremely low delay and complexity. When the users access the channel orthogonally, analog transmission of correlated information over fading multiple access channels (MACs) using modulo-like mappings provides better performance than uncoded transmission. In this paper, we propose a si... View full abstract»

Publication Year: 2017, Page(s):3037 - 3052
| | PDF (2725 KB) | HTML

Radio frequency interference (RFI) is causing performance loss in microwave radiometry, radio astronomy, and satellite communications. As the number of interferers increases, the performance loss gets more severe and RFI excision becomes more difficult. In this regard, this paper introduces the multilinear algebra framework to the multi-interferer RFI (MI-RFI) excision research by proposing a mult... View full abstract»
