this paper deals with the problem of user-server assignment in online social network systems. online social network applications such as facebook, twitter, or instagram are built on an infrastructure of servers that enables them to communicate with each other. a key factor that determines the facility of communication between the users and the servers is the expected transmission time (ett). a ...

in this paper, we present a novel algorithm for vanet using cloud computing. we accomplish processing, routing and traffic control in a centralized and parallel way by adding one or more server to the network. each car or node is considered a client, in such a manner that routing, traffic control, getting information from client and data processing and storing are performed by one or more serve...

We accomplish processing, routing and traffic control in a centralized and parallel way by adding one or more server to the network.

This paper provides a way of HTTP authentication On Alcatel OmniSwitch 9700. Authenticated VLANs control user access to network resources based on VLAN assignment and user authentication. The user can be authenticated through the switch via any standard Web browser software. Web browser client displays the username and password prompts. Then a way for HTML forms can be given to pass HTTP authen...

Database outsourcing is an idea to eliminate the burden of database management from organizations. Since data is a critical asset of organizations, preserving its privacy from outside adversary and untrusted server should be warranted. In this paper, we present a distributed scheme based on storing shares of data on different servers and separating indexes from data on a distinct server. Shamir...

Assignment problem in content distribution networks (CDN) is unsplittable hard-capacitated facility location problem (UHCFLP) because of underlying anycast routing protocol. We extend assignment problem in CDN to multidimensional facility location problem (MFLP). With our devised algorithm, assignment cost considers CPU utilization parameter along with request size and distance between client a...

In Distributed Virtual Environments (DVEs), where many simultaneous human users interact with each other in a shared, 3D virtual world, enhancing interactivity is of crucial importance, since the success of a DVE greatly depends on users’ perceptions. In general, enhancing interactivity for large-scale DVEs with thousands of geographically distributed users faces various challenges such as larg...

We study a problem of scheduling client requests to servers. Each client has a particular latency requirement at each server and may choose either to be assigned to some server in order to get serviced provided that her latency requirement is met or not to participate in the assignment at all. From a global perspective, in order to optimize the performance of such a system, one would aim to max...

Problems dealing with assignment of clients to servers have been widely studied. However, they usually do not model the fact that the delay incurred by a client is a function of both the distance to the assigned server and the load on this server, under a given assignment. We study a problem referred to as the Load-Distance Balancing problem (or LDB), where the objective is assigning a set of c...
