In wireless sensor networks, secure routing and trusted transmission of data through the nodes is one of the most challenging applications. In this paper, we are implementing the concept of trust management by using QOS metric estimation and the concept of Light weight trust management protocol is also introduced. The trust degree is calculated among the nodes by the method of direct and indire...

The rapid advancement in wireless over wired has augmented the need for improving theQuality of Service (QoS) over such wireless links. However, the wireless ad hoc networkshave too low bandwidth, and establishing a QoS in these networks is a difficult issue. So,support of quality of service in ad hoc networks is the topical issue among the networkscience researchers. In this research we are go...

The proliferation of telecommunication services and the need to manage quality of service on an end to end basis require an approach for automatically selecting services that provide su cient quality of service at minimal cost An agent based approach is appropriate for such a purpose For this reason this paper presents a social carrier recommendation method which is an essential component of ap...

Nowadays, the great benefits of cloud computing have dramatically increased the number of e-banking users. Hence, the competition in the banking industry has boosted and managers need to evaluate their branches on a regular basis. To this end, this study aims to evaluate cloud-based banking systems based on the Quality of Service (QoS) attributes using the Dynamic Network Data Envelopment Analy...

recommender systems (rs) provide personalized recommendation according to user need by analyzing behavior of users and gathering their information. one of the algorithms used in recommender systems is user-based collaborative filtering (cf) method. the idea is that if users have similar preferences in the past, they will probably have similar preferences in the future. the important part of col...

User-generated reviews are a plentiful source of user opinions and interests and can play an important role in a range of artificial intelligence contexts, particularly when it comes to recommender systems. In this paper, we describe how natural language processing and opinion mining techniques can be used to automatically mine useful recommendation knowledge from user generated reviews and how...

quality of service (qos) refers to a set of rules or techniques that help the network administrators use the available network resources optimally to manage the effects of congestion and to treat the applications according to their needs. the differentiated services architecture (diffserv) allows providing quality of service to users. the major diffserv premise is that individual flows with sim...

This paper discusses how to make a distributed object system flexible so as to satisfy the application’s requirement in the change of the system environment. Each object supports other objects with quality of service (QoS). The change of the system is modeled to be the change of QoS supported by the objects. We discuss relations among the operations with respect to QoS, i.e. QoS-based equivalen...
