Scheduling multimedia services in cloud computing environment

Currently, security is a critical factor for multimedia services running in the cloud computing environment. As an effective mechanism, trust can improve security level and mitigate attacks within cloud computing environments. Unfortunately, existing scheduling strategy for multimedia service in the cloud computing environment do not integrate trust mechanism when making scheduling decisions. In this paper, we propose a scheduling scheme for multimedia services in multi clouds. At first, a novel scheduling architecture is presented. Then, We build a trust model including both subjective trust and objective trust to evaluate the trust degree of multimedia service providers. By employing Bayesian theory, the subjective trust degree between multimedia service providers and users is obtained. According to the attributes of QoS, the objective trust degree of multimedia service providers is calculated. Finally, a scheduling algorithm integrating trust of entities is proposed by considering the deadline, cost and trust requirements of multimedia services. The scheduling algorithm heuristically hunts for reasonable resource allocations and satisfies the requirement of trust and meets deadlines for the multimedia services. Detailed simulated experiments demonstrate the effectiveness and feasibility of the proposed trust scheduling scheme.

An advanced multimedia infrastructure for WWW-based information systems

We present an advanced multimedia infrastructure that integrates continuous real-time media streams within the WWW. This new service architecture focuses on advanced facilities for dealing with multimedia contents. A mediation server is at the heart of the infrastructure. It organizes and structures the multimedia information space. In addition to simple services for accessing and delivering multimedia data, it provides new functionalities for filtering and querying multimedia content. Content servers and on-line sources deliver media streams integrated within synchronized multimedia presentations. We think that the infrastructure will offer new opportunities for WWW-based information systems and electronic commerce. This revised version was published online in June 2006 with corrections to the Cover Date.

Quality Issues in Hospitality Web Site Design and Operation

Abstract

In order to attract and retain online visitors, a hospitality enterprise needs to be mindful of and consider the quality of web site design and interactivity. The fact that the Internet development cycle has given rise to the concept of an “Internet Year” as a three-month period, illustrates the rapidity of technological advancement and underscores the need for benchmarks of quality. Although web sites debuted as a static display of text and images, advanced web authoring tools offer designers an array of dynamic, interactive, and multimedia techniques. The hospitality business web site, once developed as an electronic brochure, has likewise emerged into an interactive collection of important business productivity applications designed to complement the firm's strategic plan. A web site is deemed more effective if it: avoids clutter, restricts extraneous and irrelevant content, and minimizes download time. As the industry seeks to solidify one-to-one customer relationships, through invigorated brand loyalty, web sites are being expected to play a central role. It is for these reasons that quality benchmarks of web site design and operation assume an increasingly important role in corporate strategic planning.
