We describe a flexible web service selection model that will rate the web services based on Quality of Service (QoS) constraints. To maintain the QoS factors the non functional requirements (NFR) of a web service such as response time, throughput, reliability and security are crucial during web service selection. The performance depends not only on satisfying functional requirements, but also f...

This paper presents an active quality of service (QoS) aware service composition protocol for mobile ad hoc networks (MANETs), with the goal of conserving resources subject to QoS requirements. A problem of QoS based service composition in MANETs is transformed into a problem of the service path discovery. We extend Dynamic Source Routing protocol to discover and compose elementary services acr...

In current years, there has been an increasing attention in Underwater wireless sensor networks (UWSNs). (USNs) can be applied for many various purposes. To address the routing issue, Cuckoo Search Optimization Algorithm with Energy Efficient and QOS Aware (CSOA-EQ) based methods have proposed this chapter. Every application is important its own right, but some of them help improve sea investig...

At the present time, mobile technology is part of day to day life and activities and the mobile flora and fauna are rising, with smartphones and tablets being the principal growth drivers. The mobile phones are no longer just another device; we rely on their capabilities in work and in private. We look to our mobile phones for timely, updated and restructured information and we rely on this bei...

Research in the area of end-to-end Quality of Service (QoS) has produced important results over the last years. However, most solutions are tailored for specific environments, assume layered system architectures, or integrate QoS management within the respective service components, such that the QoS management functionality is not easily reusable. Furthermore, proprietary QoS solutions are not ...

Web services as independent software components are published on the Internet by service providers and services are then called by users’ request. However, in many cases, no service alone can be found in the service repository that could satisfy the applicant satisfaction. Service composition provides new components by using an interactive model to accelerate the programs. Prior to service comp...

This research sets out to help computational modellers to select the most cost effective Cloud service provider. This is when they opt to use cloud computing in preference to in-house HPC facilities. Cloud computing is a pay-per-use model for accessing computing resources from a variety of service providers such as Amazon EC2. Increasingly cloud providers are offering the high performance compu...
