Abstract
Content adaptation is a potential solution for tailoring multimedia web content according to the users’ preferences and heterogeneous devices’ constraints. Content adaptation can be done as third party service over the Internet. Users may pay for the service thus demand quality. The quality should include the human psychological factors. One of these factors is the maximum time a user can wait for the output to be displayed. Thus, response time is one of the qualities of service (QoS) to be considered in assessing the deliverability of content adaptation services. However, the advertised response time may not be deliverable accordingly during the actual service execution due to heavy load. Practically, the service provider should able to determine a current deliverable response time before the service level agreement (SLA) is settled with the users. In this paper, we propose a strategy for service providers to evaluate incoming requests and capable of offering the new response time. The proposed strategy takes into account the current server load and enables a mechanism for the user to evaluate whether the new response time can be accepted or not. We analyzed the performance of the proposed strategy in terms of SLA settlement under various conditions. The results indicate that the proposed strategy performs well.
Highlights
Content adaptation has already gained considerable importance in today’s multimedia communications and will certainly become an essential functionality of any service, application or system in the near future (Anna Carreras et al, 2009)

General MCDM Design Model and Methodology for Teaching Performance Evaluation This section, we will describe about the proposed of One-to-Multiple Negotiation strategy that has capability to determine that SLA can be settled with overall waiting time for all task rather than a single task. General MCDM Design Model and Methodology for Teaching Performance Evaluation This section, we will describe about the proposed of One-to-Multiple Negotiation strategy that has capability to determine that SLA can be settled with overall waiting time for all task rather than a single task This improvement strategy based from (Al-Jaljouli & Abawajy, 2012) will consider less of response time by applying overall task to a certain request. We can conclude that the overall task can be agreed by both of the broker and service provider referring to the service level agreement
