On of the main models used cloud computing is the ”pay as you go” model for the provided service. Workflow can be scheduled on virtual machines in data centers to use resources efficiently. Workflow scheduling known as one of the NP-complete problems, due to the dynamism and heterogeneity nature of cloud systems. In this paper, a Memetic Algorithm (MA) is proposed to solve the cloud workflow-scheduling problem considering cost and deadline as two objectives to optimize scheduling of scientific workflow in a cloud-computing environment. The proposed algorithm used hill climbing local search algorithm as an extra operator for Genetic Algorithm (GA) to improve individual solutions during global search. The experiment results show that the proposed MA decreases the makespan of the workflow and performs better compared to GA and Particle Swarm Optimization (PSO) algorithms.

We can improve wireless network performance and save bandwidth through the characteristic VLAN network. In addition, the implementation of VLAN greatly improves wireless network security by reducing the number of hosts receiving copies of frames broadcast by switches, thus keeping hosts holding critical data on a separate VLAN. In this paper we compare wireless network with VLAN via wireless network. The proposed network is evaluated within terms of delay and average throughput using web browsing applications and file transfer in heavy traffic. The simulation was carried out using OPNET 14.5 modeler and the results show that the use of VLAN via wireless network improved performance by reducing traffic resulting in a minimized delay time. Furthermore, VLAN implementation reduces network throughput because...

By characteristic VLAN network, we can improve efficiency of wireless network and save bandwidth. Furthermore, implementing VLAN greatly improves wireless network security by decreasing the number of hosts that receive copies of frames broadcasted by switches, so hosts holding critical data are kept on a separate VLAN. This paper compares wireless network with wireless network having VLAN deployment. The proposed Network is evaluated in terms of average throughput and delay using file transfer in heavy traffic and web browsing applications. The simulation was carried out by employing OPNET 14.5 modeler simulation and the results show that the use of VLAN via wireless network had improved the performance by decreasing the traffic resulting in minimizing delay time.

Furthermore, VLAN implementation reduces network throughput because the traffic received and transmitted has a positive relationship with throughput. Eventually, we investigated the use of adhoc routing protocols such as AODV, DSR, OLSR, TORA and GPR to improve the performance of wireless VLAN networks.
