Design and Performance Analysis of DSS (Dual Sink Based Scheme) Protocol for WBASNs

引用

Advances in Remote Sensing 2017年第4期6卷 245-259页

作者： Abdul Ahad saud Al faisal Farzand Ali Bahlool Jan Niamat Ullah Department of Computer Science Virtual University of Lahore Lahore Pakistan Department of Electronics Engineering Comsats University Islamabad Pakistan Department of Computer Science Preston University Islamabad Pakistan Department of Computer Science University of Swat Swat Pakistan Department of Computer Science Abdul Wali Khan University Mardan Pakistan

After a large improvement in health care services, Wireless Body Area Sensor Network (WBASN) is used in different fields where health care monitoring can be done continuously and from a distance. Many selected protocols are given in literature work which can improve the performance of WBASN by focusing on delay, routing and energy efficiency. In our research, we will focus on improving throughput, network life time, and decrease end-to-delay. In given research, the two sink nodes utilized and AnyCasting concept will be used. Dual Sinks based Scheme (DSS) for WBASN will be compared with existing darE, SIMPLE, LAEEBA and M-ATTEMPT protocols. DSS performance found more efficient than darE, SIMPLE, LAEEBA and M-ATTEMPT respectively in throughput. From results, DSS network life time is greater than darE, SIMPLE, LAEEBA and M-ATTEMPT with minimum delay. In DSS, energy parameter is in tradeoff with the improved parameters, because of a computation of RSSI which do more process and utilize more energy.

AIM:To assess sustained virological response(SVR) rates in a predominantly hepatitis C virus(HCV) genotype 4 infected population. METHODS:Between 2003-2007,240 patients who were treated for chronic hepatitis C infection at our center were *** data,viral genotypes,and treatment outcomes were evaluated in all treated *** with chronic renal failure, previous non-responders,and those who relapsed after previous treatment were excluded from the *** all patients,57%were treated with PEG-interferon(IFN)α-2a and 43%patients were treated with PEG-IFNα-2b;both groups received a standard dose of ribavirin. RESULTS:89.6%of patients completed the treatment with an overall SVR rate of 58%.The SVR rate was 54%in genotype 1,44%in genotype 2,73%in genotype 3,and 59%in genotype 4 *** was no statistical difference in the SVR rate between patients treated with PEG-IFNα-2a and PEG-IFNα-2b (61.5%vs 53%).Patients younger than 40 years had higher SVR rates than older patients(75%vs 51%,P =0.001).SVR was also statistically significantly higher when the HCV RNA load(pretreatment)was below 800.000(64%vs 50%,P=0.023),in patients with a body mass index(BMI)less than 28(65%vs 49%,P =0.01),and in patients who completed the treatment duration(64%vs 8%,P≤0.00001).CONCLUSION:The SVR rate in our study is higher than in previous *** with the standard duration of treatment,higher ribavirin dose,younger age,lower BMI,and low pretreatment RNA levels were associated with a higher virological response.
