TY - JOUR T1 - A Dynamic Resource Allocation Method for Virtual Datacenter Resources Using CoCo-VM Approach TT - JF - ITRC JO - ITRC VL - 5 IS - 3 UR - http://ijict.itrc.ac.ir/article-1-147-en.html Y1 - 2013 SP - 1 EP - 10 KW - Virtual resource allocation KW - cooperative co-evolutionary algorithm KW - immune system KW - agent-based greedy algorithm N2 - A dynamic resource allocation method for virtual resources in virtualized data centers has been proposed in this paper. Since resource allocation with constraint in virtual environment is NP-hard, the solution has been focused on approximate methods based on immune system mechanism using agent based model and Cooperative Coevolutionary Algorithm (CoCo-VM) that appears to perform well in finding a plausible answer [1]. The novelty of our approach lies in integrating an agent based greedy algorithm based on immune system functionality together with the cooperative co-evolutionary concept as an intelligent solution for virtual resource allocation in a large scale and distributed virtualized datacenters. Here, some mathematical analyses have been done to identify the parameters essential to assign a suggested allocation approach. Results of different evaluations in pure immune system (PIS)0F 1 and CoCo-VM methods demonstrate that, for the scenarios under consideration, the proposed resource allocation approach can significantly reduce resource consumption, increase number of successful services, and achieve higher performance.
