Wireless sensor networks, due to the characteristics of sensors such as wireless communication channels, the lack of infrastructure and targeted threats, are very vulnerable to the various attacks. Routing attacks on the networks, where a malicious node from sending data to the base station is perceived. In this article, a method that can be used to transfer the data securely to prevent attacks...

In a Grid environment, implementing a parallel algorithm for data transfer or multiple parallel jobs allocation doesn’t give reliable data transfer. There is a need to predict the data transfer performance before allocating the parallel processes on grid nodes. In this paper we propose a predictive framework for performing efficient data transfer. Our framework considers different phases for pr...

ACKNOWLEDGMENTS I would like to express my deepest gratitude to my adviser, Professor Mani Srivastava. Thank you for guiding me as I explored this problem space. I also would like to thank fellow NESL PhD student and mentor David Jea for his insightful input and feedback as I progressed through my research. The experiment for the thesis is a joint work with Dave. I also appreciate the earnest a...

Appearance of GridFTP in Grid won't substitute the old data transfer protocols, however, existing data servers confuse the users and applications. There is no unified data accessing approach. This paper proposes an implementation of web based adaptive Grid data transfer solution over multiple protocols. The system is made up of three tiers: a transfer core named PAFTP, transfer service based on...

Objectives: The aim of this study was to assess the reliability mock transfer during in vitro fertilization process Method: A case-control conducted on 134 patients included IVF/ICSI cycles. From hysterometry obtained transfer, ideal embryo replacement site, i.e. two cm from uterine fundus has been determined. Results: Significant differences were noted between area estimated and where deposite...
