Mobile cloud computing (MCC) is a new technology that has been developed to overcome the restrictions of smart mobile devices (e.g. battery, processing power, storage capacity, etc.) to send a part of the program (with complex computing) to the cloud server (CS). In this paper, we study a multi-cell with multi-input and multi-output (MIMO) system in which the cell-interior users request service...

-The performance in terms of reliability of multi-server computer networks motivates this paper. The probability limit theorem is derived on the virtual waiting time of job in nodes in a multi-server open queueing network and applied to a reliability model for multi-server computer networks where we relate the time of failure of a multi-server computer network to the system parameters. Key-Word...

This paper represents linkage network of queues consisting of biserial and parallel servers linked to a common server in series with a flowshop scheduling system consisting of two machines. The significant transportation time of the jobs from one machine to another is also considered. Further, the completion time of jobs/customers (waiting time + service time) in the queue network is the set...

this paper analyzes an m/m/2 queueing system with two heterogeneous servers. both servers goes on vacation when there is no customers waiting for service after this server 1 is always available but the other goes on vacation whenever server 2 is idle. the vacationing server however, returns to serve at a low rate as an arrival finds the other server busy. the system is analyzed in the steady st...

With the ever-increasing demands on server applications, many new server services are distributed in nature. We evaluated one hundred deployed systems and found that over a one-year period, thirteen percent of the hardware failures were network related. To provide end-user services, the server clusters must guarantee server-to-server communication in the presence of network failures. In prior w...

Server Load Balancing (SLB) technology as described by [1] has provided a fundamental cornerstone necessary to the success of the Internet. Global Server Load Balancing (GSLB) as described in [2, 3] enhances application performance by allowing the client’s server selection to be based upon server performance, network performance and the approximate network location of the client and the server....
