In conventional wireless systems, unless a contiguous frequency band with width at least equal to the required bandwidth is obtained, multimedia communication cannot be effected with the desired quality of service. We propose here a novel channel allocation technique to overcome this limitation in a cognitive radio network, which is based on utilizing several noncontiguous channels, each of width smaller than the required bandwidth, but whose sum equals at least the required bandwidth. We present algorithms for channel sensing, channel reservation, and channel deallocation along with transmission and reception protocols with two different implementations based on FDM-FDMA and OFDM-FDMA techniques. Simulation results for both these implementations show that the proposed technique outperforms the existing first-fit and best-fit allocation techniques in terms of the average number of attempts needed for acquiring the necessary number of channels for all traffic situations ranging from light to extremely heavy traffic. Furthermore, the proposed technique can allocate the required numbers of channels in less than 1 s with FDM-FDMA even (4.5 s with OFDM-FDMA) for 96% traffic load, while the first-fit and best-fit techniques fail to allocate any channel in such situations. © 2015 IEEE.

Variability-aware parametric yield enhancement via post-silicon tuning of hybrid redundant MAC units

International Symposium on VLSI Design, Automation and Test

Variations in process parameter jeopardize the parametric yield which imposes severe cost implication on the semiconductor industry. Post-silicon tunning, such as Adaptive Body Bias (ABB) and Dynamic Voltage Scaling (DVS) is a powerful technique that mitigates the impacts of process parameter variations. However, since process parameter variations are getting aggravated with continued CMOS technology scaling, the achievable performance by ABB or DVS alone is becoming limited. In this paper, to enhance the parametric yield, we integrate ABB and DVS for the Hybrid Redundant Multiply-and-Accumulate (HR-MAC) units. Simulation results based on the PTM 32nm CMOS technology show that the proposed approach enhances the parametric yield at Fast-Fast (FF), Fast-Slow (FS), Slow-Fast (SF) and Slow-Slow (SS) process corners by 81.5%, 45.3%, 59.92% and 89.08%, respectively.

Models of quantum systems on curved space-times lack sufficient experimental verification. Some speculative theories suggest that quantum properties, such as entanglement, may exhibit entirely different behavior to purely classical systems. By measuring this effect or lack thereof, we can test the hypotheses behind several such models. For instance, as predicted by Ralph and coworkers [T C Ralph, G J Milburn, and T Downes, Phys. Rev. A, 79(2):22121, 2009;T C Ralph and J Pienaar, New Journal of Physics, 16(8):85008, 2014], a bipartite entangled system could decohere if each particle traversed through a different gravitational field gradient. We propose to study this effect in a ground to space uplink scenario. We extend the above theoretical predictions of Ralph and coworkers and discuss the scientific consequences of detecting/failing to detect the predicted gravitational decoherence. We present a detailed mission design of the European Space Agency's (ESA) Space QUEST (Space - Quantum Entanglement Space Test) mission, and study the feasibility of the mission scheme.

Entanglement, one of the central mysteries of quantum mechanics, plays an essential role in numerous tasks of quantum information science. A natural question of both theoretical and experimental importance is whether universal entanglement detection can be accomplished without full state tomography. In this Letter, we prove a no-go theorem that rules out this possibility for nonadaptive schemes that employ single-copy measurements only. We also examine a previously implemented experiment [H. Park et al., Phys. Rev. Lett. 105, 230404 (2010)], which claimed to detect entanglement of two-qubit states via adaptive single-copy measurements without full state tomography. In contrast, our simulation and experiment both support the opposite conclusion that the protocol, indeed, leads to full state tomography, which supplements our no-go theorem. These results reveal a fundamental limit of single-copy measurements in entanglement detection and provide a general framework of the detection of other interesting properties of quantum states, such as the positivity of partial transpose and the k-symmetric extendibility.

Given a large number of sensor nodes distributed randomly over a 2D region, we address the problem of estimating the boundary of an area affected by an event. The boundaries are often irregular shaped and accurate estimation of such boundaries requires complex computation and data structures which the tiny inexpensive sensor nodes, in general, can not support. In this paper, given a random distribution of homogeneous sensor nodes, in case of an event, the affected nodes execute a simple O(d) distributed algorithm based on local information only, that can identify a small set of boundary nodes, where d is the maximum node degree in the network. Next, a nearly load balanced shortest path routing algorithm based on farthest-first technique is proposed for gathering the information of the boundary nodes to the sink node with low latency. Simulation results show that compared to the earlier algorithms, the proposed algorithm with less neighborhood information and simpler computing results better estimation of the covered area and gather the information at the sink node with nearly minimum latency.

Creation of backdoors in quantum communications via laser damage

Practical quantum communication (QC) protocols are assumed to be secure provided implemented devices are properly characterized and all known side channels are closed. We show that this is not always true. We demonstrate a laser-damage attack capable of modifying device behavior on demand. We test it on two practical QC systems for key distribution and coin tossing, and show that newly created deviations lead to side channels. This reveals that laser damage is a potential security risk to existing QC systems, and necessitates their testing to guarantee security.

Channel bonding allows IEEE 802.11n clients to operate at a maximum rate of 300 Mbps which can significantly improve the network throughput. But at the same time it increases the co-channel interference to the nearby APs leading to a degradation of network throughput. The issue becomes more serious when the network consists of heterogeneous clients. An inappropriate assignment of bonded channels to the APs may penalize the legacy clients served by other APs. Furthermore, activating the APs with non-bonded channels only may also penalize the n clients. In both cases the network throughput may be compromised. In this paper we propose an efficient bonded channel assignment algorithm addressing how efficiently a bonded channel can be used together with non-bonded channels to maximize the network throughput. Through extensive simulation we have shown that the proposed approach is efficient enough in terms of both network throughput and client fairness. © 2015 ACM.
