line-spacingparagraphsspacing

I am preparing my thesis with single line spaced, but it needs double line spacing between paragraphs. I am using \\ at the end of paragraph to achieve this. How to do this by using \parskip package for the whole document?

\begin{document}

\section{Introduction}
In a distributed database system, data is replicate of the most important advantages of replication is that it masks and tolerates failures in the network     gracefully and increases availability. \\

In case of multiple access a problem that must be solved while using replication is about maintaining the a generalization of the majority consensus method presented in\\

 This protocol can be viewed as specialized version of ring and tree    protocol.
 As compared to other protocols, wheel protocol can be used for arbitrary     number of nodes.
