To support hundreds of thousands of players in massively multiplayer online games, a distributed client-server architecture is widely used in which multiple servers are deployed and each server handles a partition of the virtual world. Because of the unpredictable movements and interactions of avatars, the concentration of avatars in some regions of the virtual world may cause some servers be o...

Cloud computing has become very popular in last few years. As a part of its services, it provides a flexible and easy way to keep and retrieve data and files. In cloud computing load balancing is a key issue. It would consume a lot of cost to maintain load information. Good load balancing makes cloud computing more efficient and improves user satisfaction. Many algorithms were suggested to prov...

hyosun kim’s report “trouble spots in online direct to consumer prescription drug promotion: a content analysis of fda warning letters”aims to teach marketers how to avoid breaching current food and drug administration (fda) guidelines in their online drug promotion. while kim hopes to minimise the potential for online promotion to misinform consumers and the study is carefully conducted, teach...

The world has become a global village. Today applications are developed which require sharing of resources dispersed geographically to fulfill the need of the users. In most cases applications turn out to be time bound thus leading to Real Time Distributed System (RTDS). Online Banking, Online Multimedia Applications, Real Time Databases, and Missile tracking systems are some examples of these ...

We study the online bicriteria load balancing problem in this paper. We choose a system of distributed homogeneous file servers located in a cluster as the scenario and propose two online approximate algorithms for balancing their loads and required storage spaces. We first revisit the best existing solution for document placement, and rewrite it in our first algorithm by imposing some flexibil...

On-line games are becoming more popular lately as the Internet becomes popular, game platforms become diverse and a ubiquitous game environment is supported. Therefore, distributed game server technology is required to support large numbers of concurrent game users simultaneously. Especially, while game users are playing games, many unpredictable problems can arise, such as a certain server han...

Network lifetime maximization is a critical problem for longterm data collection in wireless sensor networks. For large-scale networks, distributed and self-adaptive solutions are highly desired. In this paper, we investigate how to optimize the network lifetime by a localized method. Specifically, the network lifetime maximization problem is converted to a localized cost-balancing problem with...

Motivated by applications in energy-efficient scheduling in data centers, Khuller, Li, and Saha introduced the machine activation problem as a generalization of the classical optimization problems of minimum set cover and minimum makespan scheduling on parallel machines. In this problem, a set of n jobs have to be distributed among a set of m (unrelated) machines, given the processing time of e...
