In this paper, the authors have focused on the stochastic analysis of an internet data center (IDC), which consists of a database main server connected to a redundant server. Observing the different possibilities of functioning of the system, analysis has been done to evaluate the various reliability characteristics of the system. The system can completely fail due to failure of redundant serve...

intentional assignment of entitlements (as opposed to debts) is a legal institution which is based on the possibility of separation of entitlements from the personality of creditor and of its assignment to a third party. in the voluntary assignment of entitlements, the creditors may assign their rights to a third party. after long discussions, voluntary assignment of rights has been accepted in...

This paper surveys several applications of biased random-key genetic algorithms (BRKGA) in optimization problems that arise in telecommunications. We first review the basic concepts of BRKGA. This is followed by a description of BRKGA-based heuristics for routing in IP networks, design of survivable IP networks, redundant server location for content distribution, regenerator location in optical...

In this paper, physical layer security (PLS) in a non-orthogonal multiple access (NOMA)-based mobile edge computing (MEC) system is investigated, where hybrid successive interference cancellation (SIC) decoding considered. Specifically, users intend to complete confidential tasks with the help of MEC server, while an eavesdropper attempts intercept offloaded tasks. By jointly designing computat...

In smart cities, intelligent learning environment is an important application scenario, and class attendance checking measure to urge students attend on time ensure the quality of learning. Aiming at existing problems in checking, such as low efficiency easy cheat, this paper proposes a student management method named AMMoC (Attendance Management Method based Crowdsensing). includes two phases,...

Distributed virtual environments (DVEs) are distributed systems that allow multiple geographically distributed clients (users) to interact simultaneously in a computer-generated, shared virtual world. Applications of DVEs can be seen in many areas nowadays, such as online games, military simulations, collaborative designs, etc. To support large-scale DVEs with real-time interactions among thous...

This paper reports a study on a single server queue with bulk arrival and bulk service patterns wherein the incoming traffic depends on the state of the server which may be in operating or breakdown state. The repair of the breakdown server is performed in two phases. The operating duration of server, repair duration of both phases of repairing as well as job's inter-arrival times and service t...

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...

Abstract We consider the assignment of servers to two phases service in a two-stage tandem queueing system when customers can abandon from each stage service. New jobs arrive at both stations. Jobs arriving station 1 may go through and 2 only one phase Stage-dependent holding lump-sum abandonment costs are incurred. Continuous-time Markov decision process formulations developed that minimize di...

A high performance Layer-4 load balancer (LB) is one of the most important components a cloud service infrastructure. Such an LB uses network and transport layer information for deciding how to distribute client requests across group servers. crucial requirement stateful per connection consistency (PCC); namely, that all packets same will be forwarded server, as long server alive, even if pool ...
