Retracted

This article has been retracted: please see Elsevier Policy on Article Withdrawal ( http://www.elsevier.com/locate/withdrawalpolicy ). This article has been retracted at the request of the Editor-in-Chief. Significant similarities were noticed post-publication between this special issue article and other published sources. There is an indication that attempts have been made to disguise the copying using automated paraphrasing. Subsequent to acceptance of these special issue papers by the responsible guest editor, Sadia Din, the integrity and rigor of the peer-review process of the Special Issue were investigated and confirmed to fall beneath the high standards expected by Microprocessors & Microsystems. Due to a configuration error in the editorial system, unfortunately neither the Editor in Chief nor the designated Handling Editors received these papers for approval as per the journal’s standard workflow.
