Advances in healthcare have led to longer life expectancy and an aging population. The cost of caring for the elderly is rising progressively and threatens the economic well-being of many nations around the world. Instead of professional nursing facilities, many elderly people prefer living independently in their own homes. To enable the aging to remain active, this research explores the roles ...

For many years, electricity distribution companies have used sustained interruption indices as indicators of the reliability of service provided on their systems. Today, however, many electricity consumers are adversely affected by more subtle voltage disturbances such as sags and swells. Many utilities are well aware of such service quality concerns and are implementing extensive monitoring sy...

A composition arranges available services resulting in a defined flow of executions. Before the composition is carried out, a discovery service identifies candidate services. Then, a selection process chooses the optimal candidates. This paper discusses how the selection can consider different Quality-of-Service (QoS) categories as selection criteria to select the most suitable candidates for t...

Geographic information (GI) services are increasingly the state of the art in geoprocessing, promising novel geospatial solutions, products and services. Dynamic chaining of GI services however, presents exciting quality of service (QoS) challenges. Consequently, sustainable use of GI services demands careful consideration of the diverse user requirements and the complexities of dynamic service...

In a Quality of Service (QoS) aware communication system, a user is able to choose between various service classes, each with different reliability, predictability, and efficiency degrees. However, until now security has not been recognized as a parameter in QoS architectures and no security-related service classes have been defined. This implies that end-users have no chance of configuring the...

Many complex distributed real-time applications, monitoring and controlling the external environment, require sophisticated processing and sharing of an extensive amount of data under critical timing constraints. In this paper, we present a comprehensive overview of the Data Distribution Service standard (DDS) and describe its QoS features for developing real-time applications. An overview abou...

The number of web services with similar functionality increases which makes the service users depend on web service recommendation systems. During these days it was found that the service users pay more attention on the non-functional properties which are also known as Quality Of Service (QoS) in selecting a best Web Service. Collaborative filtering methods are used in predicting the QoS values...

Advances in the areas of QoS and IP multicasting have necessitated the need of integration of these two important features of Internet. Differentiated services (DiffServ) has been proposed as a scalable Solution for supporting QoS in the Internet. Coexistence of multicasting and DiffServ is promising since the DiffServ model can provide a scalable framework and may reduce the computational comp...

We investigate new connection-provisioning algorithms to efficiently provide signal-quality-guaranteed connections in an all-optical WDM mesh network. In the all-optical network, signal degradations incurred by nonideal transmission medium accumulate along a lightpath. When the signal degradation reaches a certain level, the connection is not usable and is blocked due to transmission impairment...

Underwater Wireless Sensor Networks (UWSNs) handle many underwater applications such as environment monitoring, surveillance and navigation. These generate varied types of traffic continuous bit rate, sporadic different packet sizes, leading to additional QoS requirements that are application dependent. This paper presents the development a Quality Service Aware Source Routing (QASR) protocol. ...
