  abstract	= {To identify the best suitable resource for a given task in
		  a grid system, under constraints of limited available
		  information, requires an elaborate strategy. The task gets
		  even more complicated if the environment is heterogeneous
		  and the availability of the resources or its information is
		  not guaranteed for all the time. Efficient and reliable
		  brokering in grid systems has been discussed extensively,
		  and different strategies and models have been presented.
		  However, this issue still needs more attention. In this
		  paper we first review different brokering models, compare
		  them and discuss the issues related to them. We have
		  identify two key areas for improving the resource
		  allocation: The \textbf{Information Flow} in the system and
		  the \textbf{Data Awareness} of the resource selection. Our
		  results show that the better management information flow
		  between different components in the grid system
		  significantly improves the efficiency of the resource
		  allocation process.}
