“…The negotiation‐based approach has been promoted to address user constraints by designing a negotiation framework. This is achieved by making user QoS requirements flexible and negotiable between the user and the service provider via a contract in order to reach an agreement . This contract is called SLA ( Service Level Agreement ), which contains the terms of the negotiation, such as QoS attributes, rewards, penalties, etc …”

Summary The aim of the current research is to develop a more accurate Web service selection approach that can deal with value constraints on QoS criteria in the user request. The purpose is to be able to promote services even when all the value constraints are not satisfied and hence rank them according to their closeness to meet the latter. For this effect, we use MCDM (Multi Criteria Decision making) methods together with suitable normalization techniques at different stages of the process. First of all, we consider an extension of the AHP method to compute and normalize the weights associated with the QoS criteria considered in the Web service selection. Second, we introduce a more consistent normalization technique, called OMRI, to normalize data according to value constraints. Third, we propose to extend different ranking MCDM methods to the OMRI normalization so that it becomes possible for them to cope with value constraints. The considered methods are SAW, TOPSIS, VIKOR, and WPM. To compare the accuracy of the extended ranking methods, we use the Borda compromise solution together with different similarity ratios. To validate the solution, several experiments have been conducted on a real dataset as well as on an artificial one.

“…Genetic-based negotiation method used by researchers to describe the problem as a space of solutions for solving negotiation problem (Abdelatey et al, 2016b). Hashmi et al (2014) used the genetic algorithm as a mathematical model for QoS negotiation problem of a web service model. The genetic approach used in multilateral negotiation for finding an acceptable solution.…”

Web services is an important in the future internet especially in the field of business. The secure interaction between requester and the provider of the service is one of the main problems. This secure interaction requires negotiation and an agreement about their security requirements. In this study, a genetic-based approach is proposed for SOAP message security negotiation. The proposed approach covers the negotiation problem as a search space of solutions for different participants. Various security levels are proposed. These levels include three key security objects identity, integrity and confidentiality of SOAP messages. The proposed Genetic-based security negotiation approach is compared with traditional time-based negotiation and the adapted traditional time-based negotiation approaches. A telemarketing case study is addressed through experimental results. Besides, the execution time and message complexity of the three approaches are provided. Experimental results show the efficiency and effectiveness of the proposed approach compared to other two approaches.

Abstract-Nowadays web service privacy gets high attention especially in the fields of finance and medical. Privacy preserves access rights to personally identifiable information. Different models have been proposed for enforcing privacy in web service environment. Getting a privacy level for protecting data transferred between consumer and provider in a web service environment is still a problem. Negotiation helps participants to get a privacy level. This paper extends web service security negotiation framework in a multilateral web service environment for negotiating privacy. A repaired genetic negotiation framework used to conduct the privacy negotiation. In privacy negotiation, the negotiation communication structure uses a broker for negotiation; where each participant sends its attributes to the broker. Negotiation using this communication structure decreases the number of messages transferred so less execution time. The genetic-based Negotiation is compared to traditional time-based negotiation. Through experimental results, genetic based negotiation outperforms traditional time-based negotiation.
