Resource allocation mechanisms in computational grid: a survey

Nowadays, the electronic resources are available almost in every institution or facility.These electronic resources could be CPU, memory, electrical devices and so on.Most of these resources are wasted or not completely utilized. Hence, the role of Computational Grid comes.Grid Computing focuses on computing resources (such as CPU), in order to achieve a huge task in a short time.Due to the high heterogeneity in Grid environment, proposing an optimal resource allocation mechanism that can work in all scenarios is a dilemma.This paper presents a critical review about some of the most widely known and recently proposed mechanisms in Grid Computing.Thus, it will give the researchers an idea about the features of the most recent and used resource allocation mechanisms in Grid
