Topology control is one of the main techniques that can be used to decrease energy expenditure and/or interference in wireless sensor networks. Less attention, however, has been devoted to algorithms that address energy and interference efficiency together. In this paper, we describe a localized topology control algorithm called TCO which is very efficient in terms of interference while minimiz...

The Wigner distribution (WD) possesses a number of desirable mathematical properties relevant to time—frequency analysis. However, the presence of interference terms renders the WD of multicomponent signals extremely difficult to interpret. In this work, we propose adaptive suppression of interference terms using the shift-invariant wavelet packet decomposition. A prescribed signal is expanded ...

in this paper, we investigated the corrected plasmon dispersion relation for graphene in presence of a constant magnetic field which it includes a quantum term arising from the collective electron density wave interference effects. by using quantum hydrodynamic plasma model which incorporates the important quantum statistical pressure and electron diffraction force, the longitudinal plasmons ar...

 In this paper, the coverage region of communication quality degradation would be indicated. The index of PER (UDP packet frame error rate) is employed to evaluate the communication quality and verify the prediction results. Moreover, by measuring the interference in terms of PER, the dependence of the microwave oven interference on the whole communication channels in the IEEE 802.11 DSSS wire...

Recent outer bounds on the capacity region of Gaussian interference channels are generalized to m-user channels with m > 2 and asymmetric powers and crosstalk coefficients. The bounds are again shown to give the sum-rate capacity for Gaussian interference channels with low powers and crosstalk coefficients. The capacity is achieved by using single-user detection at each receiver, i.e., treating...

We study the problem of controlling the interference created to an external observer by a communication processes. We model the interference in terms of its type (empirical distribution), and we analyze the consequences of placing constraints on the admissible type. Considering a single interfering link, we characterize the communication-interference capacity region. Then, we look at a scenario...

In this deliverable, smart antenna based interference mitigation methods for WINNER are presented. These methods include beamforming techniques, transmit diversity techniques, and receive diversity and spatial interference suppression techniques. The methods are investigated in terms of what requirements they put on the system, and the performance they can achieve are assessed by means of compu...

background a large amount of money is allocated to hypertension in terms of remedial and care costs, but fighting against this disease begins with education. objectives this study has been conducted with the aim of comparing the effect of two methods: face-to-face education and distance education (via short message service [sms]) on amount of following remedial diet in patients suffering from h...

We study the problem of secure information flow for Boxed Ambients in terms of non-interference. We develop a sound type system that provides static guarantees of absenceof unwanted flow of information for well typed processes. Non-interference is stated, andproved, in terms of a typed notion of contextual equivalence for Boxed Ambients akin tothe corresponding equivalence d...

Due to the share nature of wireless medium, interference is the critic factor for the performance improvement in wireless mesh networks. In this paper, we address topology and traffic has the impact on the interference, and even routing, and the interference consists of two parts. One is topology-related interference. Another is traffic-related interference. In IEEE 802.11 based wireless mesh n...
